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 .

NO PC NEEDED!!!!!!!!:highfive:
Necessary downloads from the Play Store
SuperUser or SuperSU -- One will work, the other won't -- [/COLOR][/SIZE] --A MUST HAVE for any rooted phone! Superuser/SuperSU is the app that manages what apps on your rooted device have access to su. Apps that are granted su have elevated permissions and can modify just about any part of the system. The app consists of two parts, Superuser.apk and the su binary.
Superuser.apk runs as any other app and gives you, the user, a place to see what apps you have allowed or denied, as well as view a log of what apps have used su when.
Link2SD-- DO NOT USE until rooted.--Link2SD is an application that makes it easy for Android 1.6+ users with root privileges on their phone to move applications to the SD card.
The idea behind is same with apps2sd scripts, linking applications to SD card's second partition but differs in two ways.
One, instead of linking /data/app folder (that means moving all applications), you can select applications that you want to move.
Two, it's an application which means has a user interface. You can manage your applications with few clicks.
It also provides native apps2sd features on Android 2.2 and higher. It can move any non-protected user apps to SD card (force move), with batch moving capability.
That feature uses Android's standard SD-card installation feature and does not require a second partition. It can break some apps if they are not meant to be moved to the SD card (Such as Widgets).
BusyBox--DO NOT USE until rooted. --A MUST HAVE for any rooted phone! Almost EVERY rooted applications needs BusyBox to perform their magic, if you have a rooted phone then you NEED BusyBox.
Pro version contains Backup feature (for safer installs), uninstall feature, Advance Smart install feature, the ability to hand pick the applets you want, safety check for missing applets on start, and better overall support. The pro version will receive more frequent updates than the free version will.
Root Checker (optional)--Checks for ROOT -- Use AFTER Installing a Superuser app.
BOOT-LOOP FIX

I did the boot-loop process and then the root process. I had no errors and was rooted on the first try. You should not need to factory reset. This is only the boot- loop fix and root. No new recovery or roms.
Anyone else try this?

Hi fathertomany,
Thank You, it worked, root granted and superuser installed.
Wow, I may be only the second person in the world after you to get one rooted
So to confirm and Thank, Yes, this rooted it easy and quick, can't believe it but awesome!
Thanks!

Wow 230 views and only 1 other person telling me it worked for them? I would like to keep up with this and maybe figure out some way to get roms and such, like twrp, themes, etc... But I need to know if there are any bugs or not by following these instructions. I am not a DEV but am willing to try to accomplish things people want. Currently trying to get twrp ported by someone for this phone. Whoever is willing to work on the port should pm me.
Hey I'm new to posting but I've been on android for a few years. I'm having troubles with booting into recovery mode. Whenever I try it shows some yellow text at the bottom. Something about the data directory. Think u can help me fix this please? Thank u

I have boldly went where no one has gone before. After much soul searching about bricking my son's phone because I have only followed guides, I decided that this phone was so similar to the AVAIL/MERIT that I would use that method to root his Concord. I did this because his phone ran out of memory and subsequently got stuck on boot-loop. Because this worked, I wrote this tutorial.
NO PC NEEDED!!!!!!!!
This quick tutorial will help you get into recovery and root.
What files are needed are not my work! I only decided to use the ZTE MERIT GUIDE AND ZIP for my son's T-mobile Concord(V768).
To get out of the BOOT-LOOP
1.) Power off the phone by removing the battery.
2.) Replace battery.
3.) Boot into recovery by holding Volume- and power button until the android with the triangle appears. this will appear AFTER the android that is by himself!!
4.) Press the home button
5.) Navigate to the 3rd choice - " wipe data/factory reset"
6.) Select by pressing the menu button
7.) When the wipe is complete, navigate to and select - "reboot system"
To Root
1.) Download attached update.zip file
2.) copy/move update.zip to root of sdcard
3.) Power off the phone
4.) reboot into recovery by holding Volume- and power button until the android with the triangle appears.
5.) At this screen, Press the HOME button.
6.) scroll to your second option, navigating with the volume buttons - "Apply update from sdcard" and press the Menu key
7.) Navigate to YES and press the menu key (no data will be wiped but the update will be installed and you will be rooted)
8.) Navigate to - "reboot system now" and select by pressing the menu key.
9.) Install superuser or equivalent. I installed Superuser and root checker before installing the update.
If for some reason, you get an error, try to factory reset first.
Congratulations!!! You are now Rooted!!

What carrier and version and build number are you on? You can find that under settings--> about phone. My carrier is Family Mobile (which runs on T-Mobile) and I'm running Android 2.3.7 and Build number V768V1.0.0B20.
I am having trouble getting the Concord to boot into recovery. I can't seem to get to a screen with a triangle. Can you walk through the steps to get it into recovery again or possibly post a video?
The video stayboogy supplied in the link you posted for the Avail/Merit said to put the phone into recovery mode by holding the volume up key and the menu key while pressing the power button. When I do that the concord freezes at the green android logo and does not go into recovery mode and does not boot normally. I have to pull the battery. Same thing if I hold both of the volume buttons and the menu key.
If I hold the volume down and the menu key (or just the volume down key or just the menu key) and turn on the power button I get the green android startup screen followed by a screen with a white box and an orange arrow coming out of the box pointing to a small green android. When I get to this screen pressing home or the volume up or down buttons just cause it to reboot.

I personally have not noticed this. make sure your phone is off. make sure you press the volume down button first. while still holding the volume down button press and hold the power button. DO NOT let go of either button until the android with the triangle appears. you will see the android by himself first, CONTINUE HOLDING THE BUTTONS FOR ABOUT 30 SECONDS. When the android with the triangle appears, you can let go of both buttons. Then press your home button. this should bring up your recovery menu.
USE THE VOLUME BUTTONS TO NAVIGATE UP AND DOWN.
USE THE MENU BUTTON TO SELECT YOUR CHOICES. I
BELIEVE, THE POWER BUTTON ACTS AS THE BACK BUTTON? (MAYBE JUST USE THE BACK BUTTON.) I will check this when my son gets home from school. he is the one with the phone.
remember there is NO factory wipe necessary, unless you are trying to get out of the boot-loop.

I tried again with no luck. In the Root ZTE Concord thread a few of us tried and were never able to get into recovery mode.
I just tried the steps you listed but I get the same screen with the white box and arrow and if I continue to hold the power and volume down button it causes the phone to reboot. If I keep holding down the power and volume down even after it reboots it just repeats, green android screen, white box screen, reboot, green android screen, white box, reboot, etc. I can record a video of the screen later today if you are interested.
Did you ever install an over the air update? I did months ago and I wonder if that update changes or removes how to get into recovery mode.
I have T-Mobile android 2.3.7 build number V768V1.0.0B19

I will attempt to find this screen later when my son gets home. 3:30pm central.I have only owned the phone for about 1 1/2 months. I do not believe that I have received any update OTA or any other way. my son downloads a lot of CRAP. He eventually got stuck in the pink logo boot-loop. I proceeded to do the boot-loop fix that I listed and after the factory reset to get out of it, I confirmed that it booted normally, turned the phone off and went back into recovery.
One thing I did notice about this phone is the power button. It is "weird". I am one of those that mash the buttons EXTRA hard to insure that they are being pressed. I make sure that I use both hands, one finger on each hand for each button and I hold as still as possible. Making sure that I don't toggle any buttons. at first, my phone would some how be stuck on the green android that is by himself. What your are saying sounds similar but I never noticed the white box. I think that this might be the download mode. if you have some kind of case on the phone, try removing it.
OTA update?

Have you ever applied the over the air update? I have and I wonder if that has eliminated the ability to get into recovery mode.
I stated in my previous post that I have not noticed one. I bought the phone at the end of February. I rooted the phone the night before I posted this tutorial. I will check the build version as soon as my son gets home. FYI, The rom is totally stock as no one has had this rooted, unlocked bootloader or otherwise, that I know of.

I tried again and made sure to hold the buttons firmly without moving but have the same result. Maybe your son never applied the OTA update and that's why you can get in recovery mode.

I was just wondering if the OTA update was applied by bkool96 and maybe that's why we both can't get recovery mode to boot.
If you are willing to back up what you can and then do a factory restore. You might have luck that way. I will try to get into recovery later today since my son has been using the phone but I may still be able to seeing as how I am already rooted.

Also, googling it, I noticed that I may be A** backwards. Meaning, Try Volume UP and the power button. If that works then I will edit the tutorial.

I'm pretty sure its volume down+power button. Im stuck at the green android with volume up and I get into recovery with volume down for like 3 seconds then it reboots with a yellow error message mentioning something about the /data directory

When you press the volume up and power buttons, DO NOT let them go until the Android with the triangle appears. Then follow the rest of the guide. I remember getting frozen at the green Android by himself.:banghead:

Hi!
I've made a post in the Asus forum, with no luck and I found this page where you seem more technical :
Two days ago I downloaded the Android MM 6.0 update from the Asus Homepage downloading the version WW-4.21.40.144 , since I live in Brazil and the phone was bought here. I followed all the steps one by one till it got updated.
The problem is, since then my GPS is not working (Waze, Googlemaps ans several apps).
I tryed:
1. Giving all permissions of location to the apps
2. Puting the settings in High Accuracy
3. Restarting the phone several times.
4. Switch on and off Airplane mode and 2G 3G ands 4G (I read sometimes its interference from that)
5. Waiting almost an hour with the phone outside (sunny day) to see if it detects the satellites.
6. Every app inthe appstore that promise GPS Fixing (reseting, A-GPS and all kind of tests. Funny thing, the sensor IS working acording to those apps.
7. Factory Reset
8. Factory Reset and Erase Cache from the bootmenu. (as indicated in the Asus Forum)
9. Downgraded to Lolipop again. WW-52.20.40.196
10. Again every app to reset the GPS.
Nothing worked.
To my surprise, now I have Lolipop and no GPS. So back to basics but, worst.
The Asus forum told me to Update to the latest version, which I did:
1. Updated my phone with the latest MM version. 4.21.40.223.
2. Put the location options in "High Accuracy" and permissions needed for the apps.
3. As the old software was installed after that, I tried Waze. No GPS Signal was found.
4. Did a factory reset.
5. Put the location options in "High Accuracy" and permissions needed for the apps
6. Installed the apps GPS Toolbox and Waze again, the both can't find a GPS signal. I left the phone outside for 10 minutes.
7. Tried to install the version UL-Z00A-WW-2.20.40.198-user by bootloader, but it says it cannot update to an older version, which sounds about right. (I had to try)
What else can I do? I don't mind going back to Lolipop, but when I did GPS didn't work.
Is there any chance the new Update wrote something apart from software in the chipset that cannot be undone?
Help please, I really need the GPS!
Phone not rooted.
Thanks!

After long hours of searching, reading and trying I got it fix. How?
0. Have a full charged battery or have your phone plugged to the wall (except for the USB stuff on step number 2, obviously)
0.1. Make backups of all the info in the phone, because everything is going to be erased.
1. Download the version WW-52.20.40.196 from Asus website.(unless you need the other like CN, JK, etc, see Asus site to be sure)
2. Copy it to the internal storage of your phone in the root of it (not in any folder), via USB.
3. Get to the boot loader (Turn off phone and once is off, push the power button with the Up volume one until it vibrates 2 times. Release only the power button until the menu appears) - Search the forum for more details.
4. Select "Recovery Boot" with the volume buttons and press the power button to confirm.
The next steps are all in the Recovery Menu (once it finishes every step it goes back to the original menu, no alerts, sounds or nothing. So check every now and then)
5. Make a Wipe/factory reset, and wait, it takes some time. (use the volume buttons and press the power button to confirm)
6. Make a Wipe of the cache. (use the volume buttons and press the power button to confirm)
7. Install update from Internal storage selecting the name of file you copied on step number 2 (use the volume buttons and press the power button to confirm). It will take a while.
8. Reboot the system (use the volume buttons and press the power button to confirm)
It will restart with the phone in the Lolipop version and the GPS working fine. Even after the Lolipop updates.
Marshmallow update has a bug, that at least with my phone the GPS doesn't work. Tried reinstalling marshmallow latest version after the GPS got fix, just to prove the point, and in fact, it stopped working again.
Then I did all the steps above again and went back to normal again.
I STRONGLY RECOMMEND NOT TO UPDATE TO MARSHMALLOW WITH THE ACTUAL FIRMWARE VERSIONS AVAILABLE.
I also had this problem with Marshmallow ROM, as the GPS is not working in terms of unable to locate any signal from satellites.
However, I also solved the problem with a method sounds very silly.
I turn on my GPS overnight using an application called GPS Status.
The night I turn it on, it was locating 0 satellite (it will write 0/0 SAT). However in the morning, I found that the GPS is now working, locking on 8 out of 24 discovered satellite (it wrote 8/24 SAT).
Now my GPS is working seamlessly.
Thanks! I will try it next weekend. I need my phone this week. Hahaha
I ll post when I do so.
Do you know other similar cases of people who did that and worked?
The thing is, now I have Lollipop again an I noticed how slow the system is running with applications. I d love to have the update, but not sacrificing the GPS
I decided I won't make the test because it doesn't justify the risk and time.
I'll wait for a newer update or just stay with Lollipop.
Just to let you guys know in case someone was waiting for this
I downloaded GPS Status as suggested by SleepingAran and ran it once. Now my Waze is working seamlessly. Thanks!
There's another simple solution that works:
Follow exact steps:
1. Turn on location and set high accuracy mode
2. Open google maps
3. Move your phone several times in the shape of 8 (8-10 times should be enough)
4. Close google maps and clear it from recents screen
5. Start google maps again. Profit
