Preface:​
The Galaxy Nexus (GT-I9250) is a touchscreen Android smartphone developed by a partnership between Google and Samsung. The phone and operating system were developed collaboratively by engineers from both companies. It is the third generation successor to Google's previous flagship phones: the Nexus One and Nexus S. The Galaxy Nexus has a high-definition (1280 × 720) Super AMOLED display with curved glass, an improved camera and has an unlockable bootloader to allow further development and end-user modification. Nexus devices are the first Android devices to receive updates to the operating system. The name of this smartphone is the result of co-branding between the Samsung Galaxy and Google Nexus brands of Android smartphones. The device is known as the Galaxy X in Brazil, however, due to a trademark on the "Nexus" brand.
The Galaxy Nexus was unveiled jointly by Google and Samsung on October 19, 2011 in Hong Kong. It was released in Europe on November 17, 2011.
It is one of the few phones recommended by the Android Open Source Project for building Android from source.
The Galaxy Nexus is no longer available for sale on the Google Play Store as of October 29, 2012 with the announcement of its successor, the LG Nexus 4.

OTA 4.3 (JWR66Y)​
Google begins to roll Jelly Bean 4.3 on Gnex which have some notable modifications but not at the level that users expect. Not as usual, OTA begun to roll first on yakju build not takju. Users who already got their hands on the latest firmware update have reported what is new:
- More secured ADB. (as 4.2.2)
- Fix the Bluetooth audio bugs.
- Better battery performance noticed.
- Performance enhancements.
-System UI lag also gone.
-Camera rotation lag is reduced.
-Dial pad autocomplete, can be enabled from call settings.
-you will notice more ram freeing.
-Google Hindi Input is added in "Language and imput".
-supporting of App Ops (optional permissions), see here.
** 4.3 supports now "OpenGL ES 3.0" for High-Performance Graphics and "Connectivity with Bluetooth Smart devices and sensors" and "Optimized Location and Sensor Capabilities", but unfortunately, our devices does not support it.
Support for "Restricted Profiles" is only for Nexus tablets
Did you install Android 4.3 on your Nexus device? Have you noticed anything new in Android 4.3? Please post it.

Questions & Answers​
Q1) I didn't receive OTA update and i am on unrooted stock firmware?
A Go to Settings > Apps > All > Google Services Framework, clear data, then go to Settings > About phone > System update > Check now. repeat procedure many times.
Q2) Kies program does not recognize my Gnex, i want to update firmware?
A Gnex firmware is not supported by Samsung Kies. it is updated directly from Google.
Q3) Can i make a screen shot on stock firmware?
A Yes you can! user doesn’t need to root the device or employ third-party apps just to take a photo of what's happening on screen. Taking a screenshot is simple, just press the volume down and power buttons together. The device will quickly take a snapshot of the screen and you will find it in your notifications.
Q4) What is Barrel Roll?
A As part of Google's regular antics, it had introduced a "barrel roll" trick for desktop browsers. Type "do a barrel roll" as a search term, and Google would demonstrate the power of modern browsers by flipping everything around on your screen. Your Android device can also do a barrel roll if you speak out the same command. Again, It's great fun to show off.
Q5) How can i uninstall an app. without going to setting?
A Long-pressing on an app within the app drawer pops up a couple of menus along the top of the screen. App Info gives you the boring technical stuff about how much memory it's taking up, or you can fling it off the other way to uninstall it.
Q6) How can i go directly to the quick settings menu?
A expand notification bar by sliding two fingers.
Q7) What is inverted rendering?
A Inverted rendering is a posh way of saying it makes the pages black and turns the text white, so it looks like you're reading the internet from 1997. It also supposedly saves battery, plus is easier on the eyes if you're reading in the dark. It's under the browser's settings tab, within the accessibility area - and there's a contrast slider, too.
Q8) How can i reboot into safe mode?
A Safe mode, the savior of so many Windows PCs! If you are experiencing a problem with your Gnex and you want to determine whether it is being caused by a third-party app, long-press the power button, then long-press the Power off option. Choose OK to reboot in safe mode, which completely disables all third-party apps on your device. If the problem goes away when you’re in safe mode, you should reboot your device and start removing recently installed apps until the problem goes away.
Q9) What does reset app. preferences means?
A Android gives you loads of different options for each installed app, and on the whole this is a very good thing. Sometimes it can be a bad thing, though: you may find your phone playing up because a crucial app has been disabled, or you've changed the notifications for something important like emails. In the apps drawer, you'll find Reset app preferences under the settings. This resets all your apps on a global level, returning actions and data settings to their original levels.
Q10) What is imojis?
A "Emojis" are the Japanese version of emoticons. You can enable emoji support for the default Jelly Bean keyboard by choosing Language & input in the settings app, then going to the settings for the stock Android keyboard. Here, choose Add-on dictionaries and select Emoji for English words. When you next type certain words (there's a complete list here) you'll see its symbol appear in the predictions bar.
Q11) What is the difference between takju and yakju?
A These android builds are almost the same but there are some differences in terms of their android updates. Takju: Mobiles which brought from Google play store in USA and come with a Google wallet pre-installed. In these devices, android update is pushed by Google itself and they are almost first to receive an OTA update. Yakju: Mobiles which brought from Google store but outside of USA, update are also pushed by Google, but this update might delay by some days or weeks. So, do check your android build if your device is running android build other than takju, then change it in takju build to an OTA update first.
Q12) How do i know what is my Gnex android build?
A Download Android System Info application from play store or you can check it from Maps>setting>about.
Q13) I can not see Developer Options in settings?
A Google hide this option, to enable it just go to settings---->about phone, tap 7 times on "build number" and it will be shown in settings.
Q14) how to make apps, data and sdcard backup & restore?
A Refer to post # 286.
Q15) I received 4.3 OTA update, ADB can not recognize my Gnex. What should I do?
A Download and install Android SDK, if you already have it on your PC just update tools and platform-tools. you must have latest ADB version (1.0.31). If you do not want to install Android SDK, download attached file (thx to xaueious).
Q16) How can i make my Gnex feel snappier?
A By speeding up (or disabling) the animated fade-in effects you see when switching between tasks, you’ll see a boost in performance and faster screen transitions. Start by unhiding “Developer options” as described above. Once in “Developer options,” scroll down to the “Window animation scale” and “Transition animation scale” options and set both to .5x. You can even turn each of these off and transitioning between apps and pages will be almost instant. If you ever want to go back, remember the defaults for both of these settings are 1x.
Q17) How can i improve my gaming graphics?
A If you are a hard-core gamer, you probably already know what 4x anti-aliasing is. First, enable Developer Options as described above, then go to Settings and click on Developer Options and enable Force 4x MSAA. Multisample anti-aliasing (MSAA) is a technique used to improve image quality. Since the Gnex has a GPU capable of supporting MSAA, this setting should make your graphics look more detailed when you are playing advanced games. Keep in mind this will also cause your GPU to work harder and your device may get hotter and consume more power than normal. It’s also possible that all games may not support this.
Q18) I want to see Jelly Bean on my screen, can i?
A Yes you can, go to settings---->about phone tap quickly 4-5 times on android version, you will see a big Jelly bean, touch and hold it, you will see small flying Jelly beans.
Q19) How can i customize my LED notifications?
A A free app called Light Flow Lite allows you to take control of the colors of your notification LED. It also makes your Gnex flash one color after another. This app allows you to set the notification color for over 250 applications and system events including missed calls, low battery, no signal, voice mail, calendar reminders, Gmail messages, email messages, SMS messages, MMS messages, Twitter notifications and more.
Q20) How can i put my Gnex in fastboot/recovery mode?
A Turn off your phone, press and hold down Volume Up and Down keys + Power button at the same time until fastboot (bootloader) mode (image of an Android with Start) appears then release the keys. Press volume up or down and select recovery by pressing power button. (For stock recovery, when you see an android logo with exclamation mark, press power + volume up to see the recovery menu).
Q21) How can i put my Gnex in download mode (odin mode)?
A Turn off your phone, press and hold down Volume down + Power button at the same time until odin mode appears then release the keys.
Q22) Why google voice search is crashing when i press on mic when i am on a custom rom?
A Update google search from play store.
Q23) My Gnex screen is turning on by itself, what is happening?
A It is caused by an application, usually by live wallpapers, try to find it and delete it, or install an antivirus app., i recommend Dr.Web Anti-virus, scan, delete, wipe cache and dalvik (optional).
Q24) sometimes i lose packet data (3G) when i turn it off then on, i turn off then turn on my Gnex to enable packet data again?
A There is no need to turn your phone off and on to re-enable packet data, just long press on power button, enable airplane mode for 3-5 seconds then disable it.
Q25) I rooted my Gnex, what to do next?
A It is recommended to make a nandroid backup immediately.
Q26) I rooted my Gnex 4.3, made a nandroid backup, but i can not find my backup folder?
A Use a file manager, enable root option, your backup folder is located in data/media/clockworkmod or mnt/shell/emulated/clockwordmod.
Q27) The kernel does not support PGM, is there a solution?
A change the kernel, or install intellicover application.
Q28) Do i need to wipe cache partition when flashing a new rom?
A No, there is no need to wipe cache, because when you wipe data/factory reset, cache is wiped automatically. Some said to wipe cache and dalvik after flashing a new rom to prevent any potential conflict.
Q29) I rooted my Gnex 4.3, flash custom recovery, but when i reboot into recovery, it shows the stock recovery!?
A Every OTA update places two files on device system (that are not there on a non-update stock ROM) that re-flash the stock recovery on EVERY boot. The two files are /system/recovery-from-boot.p and /system/etc/install-recovery.sh. You need to make sure that these files are either deleted or renamed, or else custom recovery will disappear when you reboot. These files serve no purpose other than re-flashing the stock recovery on every boot. So, by using something like Root Explorer, delete or rename them, and re-flash your custom recovery.
Q30) My Gnex won't start, i can not get into fastboot mode, only i can get into download mode?
A Use odin to flash stock firmware here.
Q31) What is the easiest way to install samsung driver?
A The easiest way is to install Samsung Kies.
Q32) How can i flash stock image on my Gnex?
A See efrant thread.
Q33) What about governors, I/O schedulers.....?
A See droidphile thread.
Q34) How to properly post a kernel bug (LAST_KMSG)?
A See ciprianruse88 thread.
Q35) What is the best kernel for my Gnex?
A There is no something called "best kernel". You must try many kernels and decide what suit your rom and your need.

Rooting:​
Rooting is often performed with the goal of overcoming limitations that carriers and hardware manufacturers put on some devices, resulting in the ability to alter or replace system applications and settings, run specialized apps that require administrator-level permissions, or perform other operations that are otherwise inaccessible to a normal Android user. Rooting is similar to jailbreaking devices running the Apple iOS operating system. On Android, rooting can also facilitate the complete removal and replacement of the device's operating system, usually with a more recent release of its current operating system. Rooting enables all the user-installed applications to run privileged commands that are typically unavailable to the devices in their stock configuration.
Legality: The Free Software Foundation Europe argues that it is legal to root or flash any device. According to the European Directive 1999/44/CE, replacing the original operating system with another does not void the statutory warranty that covers the hardware of the device for two years unless the seller can prove that the modification caused the defect.
On July 26, 2010, the United States announced a new exemption making it officially legal to root a device and run unauthorized third-party applications, as well as the ability to unlock any cell phone for use on multiple carriers.
Safety: I Have always said that the person should learn the Android OS before rooting. It is a good idea to have an idea of what rooting is doing and what it will affect. I would say spend your time really learning the OS which is not a small task. Then, if you still feel like it, go ahead and root. While rooting can help you learn many things about your device, it also can reap very bad consequences, such as:
-Bricking your phone (or in an easier way to explain, making your phone a pretty paper weight).
-Corrupting core files.
-Stopping OTA updates from going to your phone.
-Voiding phone warranty.
-Have your phone open to malicious software and applications that can do serious harm to your phone.
As you can see, it can reap very negative things. I have read/seen people who have literally had to buy brand new phones because they tried the latest and greatest rom. Rooting is essentially something that you must take at your own risk & caution. Generally, if you follow exactly the procedure of rooting made by developers, you will be more likely on the safe side.
Root process: See jabakuba thread.
What to do after rooting?: 1) make a nandroid backup via custom recovery 2) backup efs partition (save your IMEI and NV_DATA):
Install "terminal emulator" from play store, open it and type the following (enter after each line):
Code:
su
dd if=/dev/block/mmcblk0p3 of=/sdcard/efs.img
Then move efs.img to a safe place on your pc.

Problems can happen:​
-Stuck into a Bootloop: Bootloops are mainly caused by system files interfering with each others which cause instability and/or crash at the boot sequence. so what to do??
Pull out battery then reinsert it, boot into recovery, wipe cache and dalvik, reboot. If not, format data, system, cache using recovery and restore stock firmware (supposing that you did a nandroid backup before). if you don't have a backup to restore, flash any custom rom from your sdcard after formatting system & data & cache. If you don't have a custom rom in your sdcard, push one from your pc using adb (supposed that you have adb file or sdk on your pc): boot into recovery, connect your phone to the computer open command prompt and write the following command then hit enter (supposing that your rom is placed on D):
Code:
adb push D:\name of rom.zip /data/media/
Or
Code:
adb push D:\name of rom.zip /sdcard/
Then
Code:
adb reboot recovery
once done, go to your phone and install the rom.zip from recovery, reboot.
If none of above methods works, then flash stock image for your Gnex using fastboot commands here.
-Phone-Triangle-computer: If your phone can not boot, can not boot in fastboot or download modes, maybe after a bad flash, and screen shows phone--triangle--computer pic, so it is sort of download mode, use odin to flash stock firmware using this tutorial.
-Nexus is quietly dead: If your phone did not respond to anything, it won't turn on, can not boot into fastboot or download mode, black screen, try "OMAP FLASH", it can save your Gnex.
For 4.2.2 only:
-AOSP Rom incompatibility: After supplying all needed hardware drivers by AOSP, developers has updated AOSPA. So you absolutely need to be up to date regarding Google Bootloaders and Radios, which are not part of the Rom. Or else your device will be incompatible, unable to make calls perhaps and maybe other issues.
Regarding Bootloader, it still the same build for 4.2.2 (primelc03) but the Radio has changed to xxlj1. So you must flash Radio to the latest build using "Fastboot" or through "Recovery":
Fastboot method:(I prefer this)
Unzip "fastboot-radio-maguro-i9250xxlj1.img.zip" (attached), put unzipped image (in the file) into fastboot folder (attached), enable "usb debugging" option, boot into fastboot mode, connect your device to your PC, open a command prompt into fastboot folder and type:
Code:
fastboot flash radio radio-maguro-i9250xxlj1.img
Hit "enter"
Code:
fastboot reboot-bootloader
Hit "enter"
Code:
fastboot reboot
Hit "enter
Recovery method:
Put "cwm-radio-maguro-i9250xxlj1.zip" (attached) into your sdcard. Boot into recovery and flash the zip file.

Battery Conservation Tips:​
-Enable Auto Brightness: Brightness can lure a lot of battery if not changed intelligently with time to match the surroundings, Jellybean in this case brought the “Auto Brightness” function which uses the accelerometer within the device to detect the amount of light in the surroundings and then act upon the brightness level according to it. To enable, go to Settings > Device > Display > Brightness, and tick “Automatic Brightness“. And if you want to save more battery drain, set brightness manually at low level depending on the external amount of light.
-Remove Live Wallpapers: Using a live wallpaper is another battery sucking feature. If you turn out to be truly saving battery, make sure not to use any live wallpaper. A wallpaper with a black background uses less power than a wallpaper with a light-colored background.
-Disable Location and GPS services: Keeping GPS ON at all times, decreases your battery life, so its better to disable it while not in use. To disable, go to Settings > Personal > Location access > and switch it off.
-Disable Wi-Fi or Mobile Data when not in use: Try to avoid situations when you keep your Wifi or Mobile Data ON even when the phone is set in standby.
-Manage Sync carefully: Keeping the Sync ON all the time is another reason for decreased battery life. Enable it anytime you want, manage your emails or services and again turn it off. For those who are on work and want real-time push notifications are advised not to follow this tip.
-Turn OFF Haptic Feedback and screen sounds: To save a little more on battery, its better to switch off the screen touch sounds and vibrations. To do so, go to Settings > Device > Sound and untick Dial pad touch tones, Touch sounds. Screen lock sound and Vibrate on touch.
-Turn OFF bluetooth and NFC: Disabling bluetooth and NFC when you are not using it, is another way to save battery juice.
-Follow the method of full charge and full discharge: Don’t put your phone on charging when there is the battery remaining it for another few hours unless it’s very important. Charge it when your battery is about to get totally discharged and when you put it for charging, let it get charged totally.
-Set sleep time: Check the Sleep setting (under Display) and make sure it is set to 1 minute or less.
Keep calls short: This is obvious, but how many times have you heard people on their mobile phone say, "I think my battery’s dying," and then continue their conversation for several minutes? Sometimes, the dying battery is just an excuse to get off the phone (and a good one, at that), but if you really need to conserve the battery, limit your talk time.
-Turn OFF mobile network when not in range: Its very often that you lose the mobile network when you are travelling, so its advisable to turn OFF the mobile network by switching ON Airplane mode. Go to Settings > Wireless & Networks, tick Airplane Mode.
- After each month remove your battery from mobile phone and let it rest for an hour, it will give battery a breath and it will last longer.
-You should not have to turn off your phone to charge it. Most battery chargers deliver more than enough current to power your phone and charge it at the same time. Doing so will not lengthen the charge time, and leaving a phone on allows the user to be aware of its fuel gauge, so that you can remove it when the battery is full.
-When using a car charger, do not charge the battery when the inside temperature of your car is hot. Wait until the car has cooled before you plug in the phone.

Recommendations:​
-Too loud wallpapers may sometimes disturb the look of your home screen and make the icons quite invisible, simple or a less-colored wallpapers are always suggested as to be the best choice. But your choice is what matters.
- Use only essential widgets on your home screen - each widget consumes memory and processing power which can slow your down your phone.
- Uninstall apps that you don't use - after awhile your phone can get cluttered as some Apps are designed to always run in the background. If you rarely use an App, then uninstall it to free up memory and CPU resource.
- It is best to avoid task killers such as Advanced Task Killer. Android is designed to automatically pre-load certain applications, even if you don't load them yourself. If it starts to run low on memory, it will smartly unload the oldest running apps automatically. Manually killing tasks will only mean they get loaded in memory again. Task killers can make the phone slow, laggy, or drain battery life more quickly.
- Always use latest CWM or latest TWRP recoveries.
- Disable USB debugging when it is not in use. Leaving USB debugging enabled makes your phone vulnerable (e.g. lock pattern can be reset).
- Avoid putting your Gnex in direct sunlight, it may affect touch screen & your battery performance.
- Learn how to use ADB & FASTBOOT commands instead of using toolkits, the last could not function properly.
- Flash stock firmware using fastboot is preferred than using odin.
- Check rom/kernel.zip md5 before flashing if it is convenient.
- Always update applications, if available, for better performance.
- Make a backup of your data, applications, contacts...always ready to restore from your computer.
- Read, read and read before you mess with your Gnex.
- Always be sure that you are flashing the right thing for your Gnex variant.
- If you do not know what you are doing, so don't do it .

Questions & Answers​
Q I didn't receive OTA update and i am on stock firmware?
A Go to Settings > Apps > All > Google service framework, clear data and force close it, then go to Settings > About phone > System update > Check now. repeat procedure many times.
Q Can i make a screen shot on stock firmware?

A Yes you can, go to settings---->about phone tap quickly 4-5 times on android version, you will see a big Jelly bean, touch and hold it, you will see small flying Jelly beans.
Q How can i put my Gnex in fastboot/recovery mode?
A Turn off your phone, press and hold down Volume Up and Down keys + Power button at the same time until fastboot (bootloader) mode (image of an Android with Start) appears then release the keys. Press volume up or down and select recovery by pressing power button.
Q How can i put my Gnex in download mode (odin mode)?
A Turn off your phone, press and hold down Volume down + Power button at the same time until odin mode appears then release the keys.
Q Why google voice search is crashing when i press on mic when i am on a custom rom?
A Update google search from play store.
Q My Gnex screen is turning on by itself, what is happening?
A It is caused by an application, usually by live wallpapers, try to find it and delete it, or install an antivirus app., i recommend this, scan, delete, wipe cache and dalvik (optional).
Q sometimes i lose packet data (3G) when i turn it off then on, i turn off then turn on my Gnex to enable packet data again?
A There is no need to turn your phone off and on to re-enable packet data, just long press on power button, enable airplane mode for 3-5 seconds then turn it off.
Q I rooted my Gnex, what to do next?
A It is recommended to make a nandroid backup immediately.
Q I rooted my Gnex 4.2.1, made a nandroid backup, but i can not find my backup folder?
A Use a file manager, enable root option, your backup folder is located in data/media/clockworkmod or mnt/shell/emulated/clockwordmod.
Q The kernel does not support PGM, is there a solution?
A change the kernel, or install intellicover application.
Q Do i need to wipe cache partition when flashing a new rom?
A No, there is no need to wipe cache, because when you wipe data/factory reset, cache is wiped automatically. Some said to wipe cache and dalvik after flashing a new rom to prevent any potential conflict.
Q I rooted my Gnex 4.2.1, flash custom recovery, but when i reboot into recovery, it shows the stock recovery!?
A Every OTA update places two files on device system (that are not there on a non-update stock ROM) that re-flash the stock recovery on EVERY boot. The two files are /system/recovery-from-boot.p and /system/etc/install-recovery.sh. You need to make sure that these files are either deleted or renamed, or else custom recovery will disappear when you reboot. These files serve no purpose other than re-flashing the stock recovery on every boot. So, by using something like Root Explorer, delete or rename them, and re-flash your custom recovery.
Q My Gnex won't start, i can not get into fastboot mode, only i can get into download mode?
A Use odin to flash stock firmware here.
Q What is the easiest way to install samsung driver?
A The easiest way is to install Samsung Kies.
Q How can i flash stock image on my Gnex?
A See efrant thread.
Q What about governors, I/O schedulers, TCP congestion?
A See MBQsniper thread.
Q How to properly post a kernel bug (LAST_KMSG)?
A See ciprianruse88 thread.
Q What is the best kernel for my Gnex?
A There is no something called "best kernel". You must try many kernels and decide what suit your rom and your need. But for me AK kernel is the most active kernel in update releases that suit most roms.
Rooting:​
Rooting is often performed with the goal of overcoming limitations that carriers and hardware manufacturers put on some devices, resulting in the ability to alter or replace system applications and settings, run specialized apps that require administrator-level permissions, or perform other operations that are otherwise inaccessible to a normal Android user. Rooting is similar to jailbreaking devices running the Apple iOS operating system. On Android, rooting can also facilitate the complete removal and replacement of the device's operating system, usually with a more recent release of its current operating system. Rooting enables all the user-installed applications to run privileged commands that are typically unavailable to the devices in their stock configuration.
Legality: The Free Software Foundation Europe argues that it is legal to root or flash any device. According to the European Directive 1999/44/CE, replacing the original operating system with another does not void the statutory warranty that covers the hardware of the device for two years unless the seller can prove that the modification caused the defect.
On July 26, 2010, the United States announced a new exemption making it officially legal to root a device and run unauthorized third-party applications, as well as the ability to unlock any cell phone for use on multiple carriers.
Safety: I Have always said that the person should learn the Android OS before rooting. It is a good idea to have an idea of what rooting is doing and what it will affect. I would say spend your time really learning the OS which is not a small task. Then, if you still feel like it, go ahead and root. While rooting can help you learn many things about your device, it also can reap very bad consequences, such as:
-Bricking your phone (or in an easier way to explain, making your phone a pretty paper weight).
-Corrupting core files.
-Stopping OTA updates from going to your phone.
-Voiding phone warranty.
-Have your phone open to malicious software and applications that can do serious harm to your phone.
As you can see, it can reap very negative things. I have read/seen people who have literally had to buy brand new phones because they tried the latest and greatest rom. Rooting is essentially something that you must take at your own risk & caution. Generally, if you follow exactly the procedure of rooting made by developers, you will be more likely on the safe side.
Problems can happen:​
-Stuck into a Bootloop: Bootloops are mainly caused by system files interfering with each others which cause instability and/or crash at the boot sequence. so what to do? pull out battery then reinsert it, boot into recovery, wipe cache and dalvik, reboot. If not, format data, system, cache using recovery and restore stock firmware (supposing that you did a nandroid backup before). if you don't have a backup to restore, flash any custom rom from your sdcard after formatting system & data & cache. If you don't have a custom rom in your sdcard, push one from your pc using adb (supposed that you have adb file or sdk on your pc): boot into recovery, connect your phone to the computer open command prompt and write the following command then hit enter (supposing that your rom is placed on D):
Code:
adb push D:\name of rom.zip /data/media
once done, go to your phone and install the rom.zip from recovery, reboot.
If none of above methods works, then flash stock image for your Gnex using fastboot commands here.
-Nexus is quietly dead: If your phone did not respond to anything, it won't turn on, can not boot into fastboot or download mode, black screen, try "OMAP flash", it can save your Gnex OMAP FLASH.
Battery Conservation Tips:​
-Enable Auto Brightness: Brightness can lure a lot of battery if not changed intelligently with time to match the surroundings, Jellybean in this case brought the “Auto Brightness” function which uses the accelerometer within the device to detect the amount of light in the surroundings and then act upon the brightness level according to it. To enable, go to Settings > Device > Display > Brightness, and tick “Automatic Brightness“.
-Remove Live Wallpapers: Using a live wallpaper is another battery sucking feature. If you turn out to be truly saving battery, make sure not to use any live wallpaper.
-Disable Location and GPS services: Keeping GPS ON at all times, decreases your battery life, so its better to disable it while not in use. To disable, go to Settings > Personal > Location access > and switch it off.
-Disable Wi-Fi or Mobile Data when not in use: Try to avoid situations when you keep your Wifi or Mobile Data ON even when the phone is set in standby.
-Manage Sync carefully: Keeping the Sync ON all the time is another reason for decreased battery life. Enable it anytime you want, manage your emails or services and again turn it off. For those who are on work and want real-time push notifications are advised not to follow this tip.
-Turn OFF Haptic Feedback and screen sounds: To save a little more on battery, its better to switch off the screen touch sounds and vibrations. To do so, go to Settings > Device > Sound and untick Dial pad touch tones, Touch sounds. Screen lock sound and Vibrate on touch.
-Turn OFF bluetooth: Disabling bluetooth when you are not using it, is another way to save battery juice.
-Turn OFF mobile network when not in range: Its very often that you lose the mobile network when you are travelling, so its advisable to turn OFF the mobile network by switching ON Airplane mode. Go to Settings > Wireless & Networks, tick Airplane Mode.
Gnex secret codes:​
*#*#4636#*#* Testing menu(Phone, Battery & Wifi Info, Usage Statistics).
*#06# MEID number(Display's your IMEI).
*#*#2432546#*#* Checkin(Manually check for System Updates).
*#*#8255#*#* For Google Talk service monitoring.
*#*#786#*#* Hard Reset(Wipes/Resets Data/Profile & internal storage!) (think before you do it! no warning, no go back).
*#*#1234#*#* or *#*#7873778#*#* Open superuser application.
Recommendations:​
-Too loud wallpapers may sometimes disturb the look of your home screen and make the icons quite invisible, simple or a less-colored wallpapers are always suggested as to be the best choice. But your choice is what matters.
- Always use latest CWM or latest TWRP recoveries.
- Disable USB debugging when it is not in use. Leaving USB debugging enabled makes your phone vulnerable (e.g. lock pattern can be reset).
- Avoid putting your Gnex in direct sunlight, it may affect touch screen & your battery performance.
- Learn how to use ADB & FASTBOOT commands instead of using toolkits, the last could not function properly.
- Flash stock firmware using fastboot is preferred than using odin.
- Check rom/kernel.zip md5 before flashing if it is convenient.
- Always be sure that you are flashing the right thing for your Gnex variant.
- If you do not know what you are doing, so don't do it .

Rooting the LG Exalt LTE from Verizon (LG VN220) - Request for Advice

TL.DR; Trying to root new Verizon Android flip-phone with Marshmallow 6.0.1, ARMv7. Firmware version: VN22010B. Seems to to be locked down.
Click to expand...
Click to collapse
I'm trying to root the LG Exalt LTE, or LG VN220, from Verizon. Initially, I've attempted the common rooting kits, such as KingoRoot as well as the tools described around XDA. However all failed. I suspect the cause to be the restrictive permissions of /data/local/tmp, which prevents execution of binaries. I believe any kit using this location will likely fail to achieve anything.
As such, I've been looking to achieve the same using manual techniques. The first step, as in most rooting activity is to put the device into USB debugging mode. To do this on the VN220, first compose ##7764726220. When asked for a service code, use 000000 to access a special menu. Select the Developer Options > USB Debugging and select On. There is an additional menu below named Select USB configuration, from which you can select Media Transfer Protocol or RNDIS among other options.
With that done, you can verify that you can now communicate with the device via ADB. To do so, download the Minimal ADB and Fastboot bundle. While I was successful in querying the device with ADB with
Code:
adb devices
Trying to use fastboot simply outputs "< waiting for device >" indefinitively. It is also possible to open a shell using ADB, however attempting ADB with root will fail. I don't think this is caused by having wrong drivers, as all the other tools could detect the phone (see below), but rather a permission issue.
From there, I've try to boot in different modes, which are accessible by turning off the phone, and then powering up the device while holding the Volume Down button. This will boot into a white screen with some options, including the "Safe Mode" option which I attempted. The second mode is the "Firmware Upgrade" mode which is accessible by again, powering down the phone and powering it up again, but this time holding the Volume Up for 3 seconds.
Attempting to run the following fails:
Code:
fastboot oem unlock
That being said, I later found out that LG does provides a legitimate way to unlock the bootloader via their LG developer portal. Unfortunately the VN220 is not in the list of supported devices, nor does the procedure given applies to this phone. Additionally, it requires the device ID which fails also since it requires fastboot:
Code:
fastboot oem device-id
The other attempt I've tried is using the LG Mobile Support Too l and while it was useful to obtain the KDZ file from their website, it also failed to apply the update. LGUP didn't recognise the model. (Note that both requires the USB mode to be RNDIS to detect the phone)
Trying to run apps from the internal storage such as su or even using the chmod command only results in "Operation not permitted" messages. So even temporary root seems rather difficult.
At this point, I'd like to know if anyone has any advice on additional things I could try to root the phone, or even have temporary root.
Thanks in advance
@cyberrecce

Why?
First of all thank you, I've been looking for that service code to enable developer settings / adb since I discovered the phone secretly runs Android. But I don't see why we would need root, I've been using adb to side load apps since I can't get to a menu that allows it

1. Why? To install a custom ROM.
2. Did you get any issue with certificates when side-loading apps? I keep getting INSTALL_PARSE_FAILED_INCONSISTENT_CERTIFICATES. Can't seem to find the "Install from Unknown Sources" option.

Same problem

re: the certificate error for side loading apps...
Code:

turns off the unknown source block, but I'm still getting INSTALL_PARSE_FAILED_INCONSISTENT_CERTIFICATES
Could the apk itself I'm trying to use have a bad certificate? Or is there another solution?

Just curious - any success or updates. I can't seem to get past " INSTALL_PARSE_FAILED_INCONSISTENT_CERTIFICATES"

For installing apps I'm still not getting past INSTALL_PARSE_FAILED_INCONSISTENT_CERTIFICATES
I even tried pulling an apk from my LG G4 that successfully installed on that device and tried installing it on the Exalt, but same error.
The biggest reason I've seen for the INSTALL_PARSE_FAILED_INCONSISTENT_CERTIFICATES is apks that are signed poorly. When I check the apks I'm using for their signatures with the JDK it says one or more of their signatures lack a timestamp which can cause problems.
Also, downloading the apk from the Exalt's browser and trying to install from either
settings > phone settings > storage > phone > explore > downloads > open > install
or
tools > file manager > internal storage > downloads > open > install
has been coming up with "app not installed" after it tries to install the apk.
I'm not really giving up though, I just don't really know where to go from here.

Can you please share with us the KDZ file?

You will need to:
- unlock it’s Bootloader. If the “fastboot oem unlock” command will not work (and I’m quite sure it will not, since we’re talking about a USA LG device), you can stop here and throw the phone out the window.
- if by some any miracle you will be able to unlock the bootloader, you have two ways of rooting it:
1. Using TWRP and a superuser zip file (magisk or the now Chinese owned supersu). The main problem with this is that you will need to compile TWRP yourself, since I doubt anyone will bother for such an obscure device.
2. Using a prerooted boot image. You will need the stock boot image, install the latest magisk manager, let it root it and then flash it via fastboot. This is particularly difficult because you will need to decrypt the kdz file (if any available) in order to get the boot.img
Even if by a greater miracle you will be able to get 1 or 2 working, there still is a huge chance that the fastboot flash command will be disabled.
Forget about solutions like king/kingoroot. Best case scenario they will fail. Worst case scenario they will softbrick the phone by gaining temporary root and then modifying /system. That will in turn trigger dm-verity which will cause the soft brick.
Forget about the scams like oneclickroot. Their so called techs will try the aforementioned and fail and you will waste your $40.
Sorry To deliver the bad news, but there’s no way out of it.

Thanks for taking your time, to help me.
I will check if I can unlock the bootloader.
Thanks alot

Any sage advice on the [INSTALL_PARSE_FAILED_INCONSISTENT_CERTIFICATES] issue when sideloading apps?
 @jfn0802 said they had success with sideloading, but haven't been online in ages, and none of the rest of us seem to have had the same success. Minimum, that's what I would like to accomplish.
[side note, has anyone switched from Verizon with this phone? I'm looking to, but I'm wondering a couple of things like, does verizon have the mobile hotspot function restricted from use on other carriers? & etc & just wondering how it's doing off-verizon for anyone.]

Isn't that what turning on the "install from unknown sources" option should do? I still get the Install Parse Failed after switching it on with ADB.
@98jbsz I've tried to uninstall without success. What way did you do it? And does it just leave a blank space in the menu screen?
[Less on topic, sorry again, but has anyone seen the LG Wine LTE? http://www.lg.com/us/cell-phones/lg-UN220-lg-wine
It's strikingly similar to our friend the Exalt LTE here, but it seems less carrier branded/available at US Cellular, so I'm wondering if that would make a difference?
Major differences Wine LTE has more 4G bands (2/4/5/12/25) versus Exalt (4/5/13), which kind of has me kicking myself, because travel and 4G was one of the reasons I bought the Exalt. Both have quadband GSM and WCDMA, but interestingly the Wine also has CDMA.
Beyond that, there are some more smaller differences I scavenged from their LG pages, Exalt has more bluetooth profiles, supports more music formats, has more GPS capabilities, wifi calling, and 1 more ringtone. Wine has more supported video formats, and an FM radio.
I'm curious about what/if the Wine would have for sms messaging (I doubt it'd have Verizon's message+) and instead of my Verizon app...]

Alright, I also managed to uninstall my verizon and verizon's cloud app using
Code:
adb shell and the pm uninstall -k --user 0
But the Verizon apps folder on the menu screen remains, although it's empty. Any ideas on how to remove it?
Then I tried to install an apk using
Code:
pm install
and it came back with [INSTALL_FAILED_INVALID_URI] which...is a different than [INSTALL_PARSE_FAILED_INCONSISTENT_CERTIFICATES], but not better.

right, but when you first copy the APK to the phone, and then you install it, you will see the [INSTALL_PARSE_FAILED_INCONSISTENT_CERTIFICATES] error. still not a solution

ATT Note 5 Native Tether/hotspot (NO Root) 6.0.1 MM

I am using an at&t note 5 (sm-920A) i downgraded from Nougat EQC6, 7.0.1 to 6.0.1. MM CPK1 with Binary 4 bootloader. This phone has never been rooted.
I now have access to hotspot in my notifications drop down menu, and USB tethering along with Bluetooth tethering work by just going to the option and switching them on.
My Goal was initially to downgrade to 5.1.1 to get root so i could make use of the Native Tether/Hotspot and other root apps on my ATT Note 5.
I am using this phone on the Straight Talk network.
This is my first how-to and first post. I apologize if i post in the wrong section or am unable to give more help to those in need.
I've searched/googled and although i have found workarounds i have not found any how-to's to get to this end result.
Ive been using my note 5 this way for a few days now with no problems. disabled att bloatware, knox, and system updates with package disabler pro.
With not having any issues, I flashed back to the 6.01 firmware to check my steps and write this how-to. Will update if anything changes.
WARNING!!
Some things i did may be unnessary but were in my process at the time of writing/doing this so are included
I haven't tested everything on this phone.
I don't know if there are any bugs.
I don't know what will happen when updated.
I do not garuntee this will work for you.
I take NO responsibility if your decision to try/do this fails.
The Search button and google were my biggest helpers.
Here is my process as laid out and straight forward as i could think to write it.
Things you will need:

Big Thank you to these guys for posting this stuff, and everything else they post.
I am assuming you know how to put your phone into download mode and use odin in the following instructions. I left my phone connected to my pc with sim card in the entire process.
1. Unzip N920AUCS4CPK1, then Flash using odin. Use all 4 files in their respected spots. nothing else has to be changed hit start.
After reboot I setup up the phone enough to get to settings and enable developer options. making sure to turn on adb debugging and oem unlock. then rebooted to download mode
2. In Odin, Flash N920AUCE2APB2.tar in the BL slot and COMBINATION_FA51_N920AUCU4APL1_CL6053901_QB11816686_REV00_user_mid_noship.tar in the AP slot. (I flashed these two at the same time)
Phone will reboot to binary splash screen then start regularly. For me the phone Played boot music and (vibrated then vibrate twice) repeatedly. Bootloop
If this happens to you as well,
2a. Shut phone off by holding volume down key and power button.
(If you are brought to a screen that says power key long press in yellow with other information below[well call this the info screen, not sure on its proper name],
then power off by holding volume down key and power key again, releasing both when screen goes blank.
2b. When the phone is completly off reboot to recovery by holding volume up key and power key.
Do a factory reset and wipe cache. Then reboot. (If it freezes at cache complete, power off with volume down key and power key).
Holding power button for 10 seconds or more will boot you to info screen again.
3. Your phone should load to a home screen with what looks like a debugging menu as the background.
4. Turn phone off and boot to download mode.
5. In Odin, load BL, AP, and CP from N920AUCS4CPK1. Leave CSC blank. No other options should be changed in Odin.
6. You will reboot to recovery. Use reboot option. dm verity check will start then phone should reboot to normal setup initialization.
7. If for some reason your phone shows the wrong storage size, go to back-up and resert in settings and o a factory data reset mine was showing up as 16gb where as it is 64gb
That was everything i did.
If with straight talk send a text to 611611 with the mesage being apn.
afrter a few minutes they will send a configuration message for browser and mms.
Install both. They should say installed when complete.
For others you will have to input your apn settings manually.
My phone showed H+ for the first few minutes, has been showing 4g ever since.
Just a few thoughts before i post, but are in no way tested or confirmed...
I'm thinking coming from cpk1 full firmware you could just flash the combination file in the AP slot.
Then after reboot to Download mode flash the cpk1 firmware without the CSC file and hve the same result,
but I havnt had a chance to test that yet as i need my phone running, and will soon have to go to work.
The main reason the N920AUCE2APB2.tar file was used was because i was playing around flashing different files it may or may not be needed. further testing is needed. but it was there during this process so i included it. Again I apologize if this could be simplified or if i left anything out. any comments are appreciated positive or negative. Thanks

So i did a little testing. Flash cpk1 all files. Then flash the custom binary and rebooting to download mode. Then flash the cpk1 files again minus the csc file. Leave that slot(csc) empty in odin and it will give you native hotspot and tethering. You get hotspot from notification drop down menu and No more contact att. It will take away the calls over wifi option though.
I will edit this walkthrough (if you canveven call it that) soon to reflect the changes. Thank you for reading.

[ATT Note 5. on straight talk]
This process also works using this firmware. i updated from cpk1 using my process in post #2. i left out the (csc) and pit file in the N920A_N920AUCS4EQL1_ATT_USA_7.0.zip huynhlam posted in the link above. I am now on 7.0 with native hotspot and mobile hotspot icon in the notification drop down menu working . i can upload pictures but atm im not familiar with the best free file hosting sites so any suggestions would be greatly appreciated. i will keep trying different firmwares and update with results.

I am using an at&t note 5 (sm-920A) i downgraded from Nougat EQC6, 7.0.1 to 6.0.1. MM CPK1 with Binary 4 bootloader. This phone has never been rooted.
I now have access to hotspot in my notifications drop down menu, and USB tethering along with Bluetooth tethering work by just going to the option and switching them on.
My Goal was initially to downgrade to 5.1.1 to get root so i could make use of the Native Tether/Hotspot and other root apps on my ATT Note 5.
I am using this phone on the Straight Talk network.
This is my first how-to and first post. I apologize if i post in the wrong section or am unable to give more help to those in need.
I've searched/googled and although i have found workarounds i have not found any how-to's to get to this end result.
Ive been using my note 5 this way for a few days now with no problems. disabled att bloatware, knox, and system updates with package disabler pro.
With not having any issues, I flashed back to the 6.01 firmware to check my steps and write this how-to. Will update if anything changes.
WARNING!!
Some things i did may be unnessary but were in my process at the time of writing/doing this so are included
I haven't tested everything on this phone.
I don't know if there are any bugs.
I don't know what will happen when updated.
I do not garuntee this will work for you.
I take NO responsibility if your decision to try/do this fails.
The Search button and google were my biggest helpers.
Here is my process as laid out and straight forward as i could think to write it.
Things you will need:

Hello Badbrane, I followed your instructions and I succeeded
Thanks a lot!
EDIT: After some testing I found out a bluetooth issue.
The first time I turn the device on, the bluetooth works fine. Then, after a reboot, I can't turn bluetooth on any more.
If I go through a Factory reset I will get the bluetooth working again, till next reboot

I need some help. I'm stuck in 2b (yellow information screen). when i hold [volume down] + [power button] it restarts instead of turning off. What should I do?

The combination file is no longer on Android file host. Any chance you have another link?
Im blind

https://1drv.ms/f/s!AhYiTPM1C3QkbQJswYeC0PtRMEY
not sure how long this link will be live but here's N920AUCS4CPK1.rar and COMBINATION_FA51_N920AUCU4APL1_CL6053901_QB11816686_REV00_user_mid_noship.rar. sorry it took so long to reply.

hold vol down and power till screen goes black immediatly change to 3 finger salute for dl or recovery. have to do it fast, that or wait for the battery to die and resume from there.

I havnt really messed with the bluetooth much on my note 5 since i did this process. there are definetly a few bugs but my only concern was being able to use hotspot and tether. found out later that the system will try to auto update but it crashes every time so i no worring about hitting binary 5, as far as i know that is

Just tweak it [Tab S4] - debloat, root, plugins, battery...

Tab S4 stock cleanup actions
phablet guide fest continues V30->Note9->6T->Mi9->S10->7T->Tab S6->Tab S4, time to provide some thoughts, easy to click links and guides. Goal is to have a clean device after each update, and have a helper script running at boot or on demand. This is a tablet, we want to achieve flat battery graphs when it is unused (picture attached), hopefully charge once a week with slight usage.
Debloat
What the script does:
* choose 8 categories of app removal, in the beginning of the file
for each say 0=skip 1=remove 2=revert back
* use more switch to disable some questionable/helpful stuff
* disable up to 80 apps with possibility to revert back
* remove usage access for google (do manually)
* remove device admin backdoor "Find My Mobile", you won't recover stolen device this way lol, it doesn't work with Secure Startup! it's useful for Govt.
* remove proca (which was slowing down tablet after rooting), if it doesn't work from your shell, edit the file as below
Tested ok on March stock Pie firmware. Samsung has too much bloatware installed, and requires shocking permissions to run some basic services. We will further need to reclaim privacy. As for debloat list, i've cooked the list based on knowledge of each process, its current presence in the Pie firmware, and what would fit the tablet usage. In this case, i'm leaving Samsung account, Galaxy shop and few pen apps and we assume XPrivacy is sending these snitch services bogus personal details.
Download: (file attached)
Installation:
- run in su terminal once or add to any startup script (3C\Device mgr\Scheduler can assign scripts from /storage/emulated/0/Android/data/ccc71.at/scripts), or to magisk
Rooting
We want encryption. There are no ROMs, and TWRP can be used for many other tasks without access to your files.
OEM unlock in dev settings
when turned off and rather plugged it to your PC with drivers installed, hold Power & Vol+ & Vol- til you see download screen, confirm with Vol+
in ODIN, slap TWRP into AP while "Auto reboot" is unchecked
hold Power & Vol- to exit download mode, then Power & Vol+ to enter recovery
in TWRP, slap kernel and Magisk into tablet from SD card or USB (can be usb flash, can be other mobile, can be adb)
in TWRP, say boot to system and wait 5min
check Magisk app status, enable USB debugging in dev settings
kernel: WETA recovery: TWRP 3.3.1 for PIE SM-T83x
watch kernel log for 20sec
Code:
dmesg -Tw|grep proca
if proca messages appear open /vendor/etc/init/pa_daemon_qsee.rc and comment the lines
You should enable "Secure startup" in "Biometrics and security" settings. Recovery should fail reading encrypted drive sda27 because of its crypto flags and logical mapping.
Which plugins to use
Similarly to Mi9, collecting what i think is useful to keep on stock rooted firmware.
Magisk plugins:
* Riru - Core, Riru - Ed Exposed -- brings XPosed to Pie. Need also installer. Make a choice SandHook/Yahfa bipolar release, i never found out which one is better.
* libsecure_storage companion -- helps us keep the bluetooth pairings
* (optional) YouTube Vanced black themed -- brings usable YouTube experience. Unfortunately it's now a horror to install (v15), but v14 from Magisk still works.
* (optional) Move certificates -- perhaps
* (impossible) QuickSwitch -- there's no pill but Samsung custom recents... oh how glad i am for it now! Android10 cancelled this fantastic Pie pill already and you can scroll apps in OneUI!
XPosed plugins:
* Xposed Edge Pro -- a must have and best plugin
* XPrivacy -- Screw the big brother. Must have of the century. Disabling analytics, tracking, telephony, network, identification for all visible apps and all Google and Samsung apps with some exceptions.
* Firefds kit -- so this is our main customization app irrelevant here: ..and enables the very important call recording, which is beutifully integrated into call history. Bye bye external apps. Also for Samsungs it forces Restart "recovery"
* (optional) Xposed Dex -- some tweaks
* (optional) afWall -- Problems with this firewall and some VPN clients for years. Using AdGuard now and happy. It can even control DNS, no need one of those paid lausy apps. This plugin should by disabled in Xposed.
* (optional) Exi for Swiftkey -- you can make Swiftkey great again, GBoard is still the best, Samsung keyboard is very good, but too tall and leaves gap in fullscreen mode
Root apps:
* TitaniumBackup -- a must since Android was born
* Adaway -- a must but with AdGuard not so.. but i use both
* AdGuard -- can filter more and can amend requests.. that's a game changer. You can have a efficient proxy when rooted.
* 3C toolbox -- too helpful not to pay for the biggest package
* (optional) Root Essentials -- a multitool, have a look
* (optional) MiXplorer -- best file manager, replaces spyware ES File explorer you had before. Edits root files comfortably even when other editors don't
* (optional) FolderSync -- best sync tool
Battery
Battery saving:
- tablet should not be neccessarily always connected, receive notifications, so why not keep it dead when the screen is off
- the key is to disable background network activity:
disable it overall by Medium Power Saving mode
disable background network for individual apps (there's "Allow background data usage" and also nice "Allow background activity" checkbox)
force it with 3C (Device Mgr\Profiler) or Adguard (App Management)
- can't see wifi switch.. to turn wifi off when screen off. no wifi scanning drainer or other "intelligent" bs functions there either. just "Hotspot 2" - turn off.
- nearby scanning should be off, what a useless function of finding unknown devices - once you pair the known, what's the sense? or you keep connection 10 new bt devices each week? just a drain and endless beacon
- location can be off, and again it can be scripted by turning on only when screen is on by 3C
- not installing {LSpeed, Naptime, Servicely, FDE, LKT, Universal GMS Doze, Sysconfig patcher} here
- no signifficant doze functions here {AOD, fp icon, dt2wake, raise2wake} to speak off
- we want battery to remain flat when screen off, last tablet i had could do -1% per week! let's do it here
Other
- i like tender boot screen indicating knox off status, no need to flash boot logos
- no boot keys needed like on Tab s6
- not using multidisabler as i'm on stock and i do want encryption on every device ever
- how to launch camera quickly?? still dind't find out
- don't be afraid to use another device (mobile) as USB drive.. this way you can restore your apps directly via TitaniumBackup without copying it first! also Smart Switch can be used from non-Samsung phones, but it is as weak as Google backup ever was - no data restore

What do you do to run this exactly?

copy the file to storage. open su terminal. Get any root terminal app (ConnectBot, 3C Toolbox, or adb shell) and run as root. I run this script as autostart on each of my devices.
wifi_standby_test: first battery standby test: 37 hours to 91%, i've 'charging protection' so approx 93% that give us 0.19%/hr drain with wifi and bluetooth on. 10x less then a mobile (S10). Good start, nice 3 weeks of standby potential, but let's try medium power saving mode to squeeze it to over month of standby.

Will i loose my data while rooting? Im on Build number PPR1.180610.011.T835DDS4BSL2

backup, try and let us know the reason why usual root methods wipe data is to remove encryption, we don't need that.

ah i see... you need this checkbox unlocked to flash. this device will wipe itself if you just toggle the checkbox. so in the end, data will be wiped in transition from unrooted state.
and regarding backup, just conventional methods like google backup or deeper cable backup by Helium which can partially substitute TitaniumBackup on unrooted device.

How did you get Weta running on the March firmware when it isn't supported?
NM, I see you just used the kernel part.
Running this script did very little for me - no options were given, just a few packages disabled before it errored out

Thank you for the script! It made a great difference on my tab s4, I was able to enable back Chrome and Google.
My device was lagging before... Thanks again for the write up...

Any suggestions on installing apps to sd card? The option under dev options, to force install apps to sd card is not really good.

I just purchased a refurb Tab S4, it should be arriving over the weekend. The seller notes that the S4 is on Oreo.
I noticed references to Pie here. Should boot and I let the tablet update to the latest release from Samsung, and then root / debloat as described in this thread after the Pie update?

I noticed references to Pie here. Should boot and I let the tablet update to the latest release from Samsung, and then root / debloat as described in this thread after the Pie update?

My Tab S4 arrived today. Should I allow any updates from Samsung be installed before I run through the rooting process described here, or should I do the rooting before getting the Samsung updates?

yes..why rooting an old version.. no OTAs later so you'd have to update manually again.

Thanks!
But, as it turns out ... I won't be able to root or debloat anyways. I purchased a refurb Tab S4 that appears to be in excellent like-new shape, but it was also mislabeled on Amazon.
Instead of getting a SM-T830, I received a SM-T837T (T-Mobile version). I plan on getting it unlocked so that I can use it on AT&T, but from what I understand, it's unrootable.
Thanks, tho!

I was wondering about this. So there is no way to update once rooted, other than a full clean flash and start again?

later use Frija to get new firmware and update. cleaning is only on first root as we can't avoid it when switching the OEM lock.

This thread is really one of the best thread for tab S4
Thanks for that

Guide for flashing system image:
Flash recovery for snapdragon version, i'm using: OrangeFox Recovery is also provided for exynos soc
Please do everything that is written for flashing recovery (Installation), u need to disable encryption and wipe data
reboot when you sure recovery is permanent and check if phone is on "hello screen"
How to boot on recovery first time BEFORE "hello screen":
Uncheck reboot after flash AP recovery in Odin, unplug cable and then push vol - and power -> immiedietly after turn off download mode hold vol + and power and plug in cable -> now should work
Flash GSI image:​First you need to download image from here: here or find thread here: click. This images have Google Apps allready included.
Remember to use arm64 with b !
Reboot to recovery
Now u should see on PC when u connect via cable internal memory - copy image to folder, probably should be "Fox" or create new
Touch files, find image
Now select to flash System image
Reboot
And thats it you should boot to system.
Post install settings​On Phh Treble Settings set:
Samsung features:
Use alternate audio policy
Enable stereo audio mode
Enable extended brightness range
Enable double tap to wake (if u want)
Enable reversed wireless charging (if u want to reverse charge other device)
Enable access to all cameras
Enable extra sensors
Misc features:
Force FPS to [email protected] if you want 120Hz refresh rate display
On camera set expose aux cameras and force enable camera2api
Select Use System Wide BT HAL if u use bluetooth headphones and don't have audio (tested on galaxy buds 2)
Qualcomm features:
select use alternate camera profile if u have trouble with ultrawide photos
Root access on Pixel Experience Plus:​
You should first patch boot img from your stock samsung rom what you allready using
U need to select ap tar.img file in Magisk and wait to be patched
Extract boot.img from it after patch
Flash boot img in recovery on boot image
Root stays even if you reflash system on other GSI
Works:
WiFi 2.4GHz and 5GHz
RIL (phone and mobile data)
Bluetooth with bluetooth audio
fingerprint sensor
Google Pay with NFC (you need to pass safynet check if you have magisk)
120Hz display
Camera front and back (you need other camera app for using ultrawide photo)
Fastcharge
Stereo speakers
Galaxy accessories (Watch 4 and Buds 2 tested)
MHL mode
Probably other functions too
Not work/problems:
Netflix have videwine L1 but no HDR content support
Movies only record max on 30FPS on 4K
On the go don't work any of galaxy wearable devices, you need to patch via magisk some files
Clear View cases (phone don't response for open or close case) even on AOD
Some problems with updates for Chrome and web framework (need to install manual newer version)
Device is showing as Huawei Nexus 6P need to be changed somehow to our model
Workaund for Galaxy Wearable and Google Pay:​
Magisk need to be in zygisk mode
Flash Universal SafetyNet Fix, here: github download
Install FoxMMM for magisk modules finder here: here, find and install MagiskHide Props Config
Flash this for workaund of wearables: gdrive module download
Now download Galaxy wearables from store, and plugins for your proper device form apkpure or other website.
You need to allow all permisions for apps first
Try to find your watch and pair it, you need to be fast to accept all pop ups - u dont need to login to samsung account , for me got it after 2-3 try, you should see "prepairing device" etc.
For galaxy buds should be easier just find it and pair.
Google Pay works out of the box after installing this modules
Get better sound and equalizer:
If you want to have better audio - you need to flash magisk module ViperFX
Download here: click here on github
Flash via magisk
Uncheck legacy mode for work

Greetings. Since this appears to be a "guide," I have changed the thread designation accordingly.
-Regards: Badger50

@hunter3000 i think you can change the model number in the build.prop if im not mistaking

Hi, can i flash it like the offical pixel experience? Because the offical one is a zip file and this one not

this is GSI style rom, not specific ROM for specific model, so you must flash it by twrp or by fastboot command. Like universal rom for all phones than have project treble.

Thanks for support
Im looking to xda everyday for a stable pixel rom

Majority of GSI are stable but you will have bugs tho. Like either bad battery life or camera isnt working

On this build all functions is working, for camera ultrawide support you need 3rd party app like OpenCamera.

you must disable encryption to boot to non official rom, so you got answer for your question

Master, any solution to this ? "Device is showing as Huawei Nexus 6P need to be changed somehow to our model ", and Call Recording is working on this version ? many thanks for your hard work to G990B version.

This device showing is related to magisk safenet fix for working root with NFC and banking apps but probably also because of GSI rom as is. No call recording as is stock Pixel Experience ROM u need to root and use some magisk module.

Works great on my Samsung s21fe just charging.. sometimes works then other times says it's charging and then does down. Doesn't really go up unless phone is off.

May I know if VoWifi / VoLTE works?
