[HOW TO] Root only STOCK/No Custom Recovery

Taken FROM http://rootzwiki.com/topic/11732-galaxy-nexus-root-procedure-broken-adb-method-dont-use/
With the big change of YOU WILL BOOT LOOP WAIT FOR ADB TO RESPOND and push all the commands then pull the battery and disconnect your USB cable and reboot normal you should have perm root!
**As always RootzWiki nor myself are responsible if something goes wrong. Root your phone at your own risk with the understanding it will void your warranty and there is always a chance of something going wrong.**
*This method WILL WIPE YOUR DATA*
First download Galaxy Nexus FYA Root Package and extract it to c:\gnexroot (for the purposes of this guide)
Also if you wipe and format remember to re-enable Debug mode before restarting processes listed above.
Method
1. First, navigate to C:\gnexroot and install the Samsung drivers (Samsung_USB_Driver_for_Moblie_Phones_v1_4_6_0.exe)
1. If those drivers dont work download pdanet from here http://forum.xda-dev....php?p=19709279 and let pdanet install the drivers for you. Worked for some of us.
2. With the phone turned OFF, hold VOLUME UP + VOLUME DOWN and power the phone on. This will put you in bootloader mode.
3. Navigate again to C:\gnexroot, and hold SHIFT on your keyboard, and right click in the white space. Then, click 'Open command window here'
4. In the command prompt, type:
fastboot oem unlock
You will be prompted to confirm that you wish to unlock the bootloader. You do, of course.
5. Once the bootloader has been unlocked, it's time to boot up the device using the insecure boot.img (ro.secure=0 set in the ramdisk). This essentially means you have permanent root for the duration of this boot session. In order to boot up using that boot image, simply type:
fastboot boot boot.img
Don't expect to see anything wildly different during the boot process - it will boot as normal.
6. Once the phone has booted, in the command prompt window, type the following commands, pressing enter after each line:
adb root
adb remount
adb push su /system/bin
adb push Superuser.apk /system/app
adb shell chmod 06755 /system/bin/su
adb shell chmod 06755 /system/app/Superuser.apk
adb reboot
Again I did NOT write these steps nor did I take credit for this procedure. My goal was to have all this information easy to access here so people don't brick their new device
Edit:
If you get stuck at the google logo and cannot push adb commands, pull the battery and usb cable then reinsert and reboot. If this doesn't work Reboot into recovery and wipe everything and start over.

If you do a factory restore remember to boot at least once after and re-enable debug mode.

anyone had the issue of not being able to unlock the bootloader?
i ran the command "fastboot oem unlock" and it just sticks at the response: <waiting for device>
but nothing shows on my phone.

I would guess your computer is not recognizing the device. Try installing the drivers and connecting the phone to the computer while it is in normal mode not the bootloader. It should install the drivers correctly that way and your computer will then recognize it when you boot into the bootloader and the commands should work.

yea... you are right... it was the samsung drivers not fully loading. re-installed the drivers then doing a windows update showed that there's a new set of samsung drivers on the windows update that needed to be installed. that did the trick.

The superboot method worked just fine for me.

You must be in recovery mode. Turn the phone off, press volume up and down as well as power. Keep it there until you're in recovery and then unlock.

Its not recovery mode, but fastboot mode. If you are in recovery fastboot won't be recognized. Looks like he got it fixed by checking his drivers.

can you also use this method for a Verizon Galaxy Nexus???
http://forum.xda-developers.com/showthread.php?t=1392310
is there any difference?

Superboot method actually does the same thing as this method from what I read just one is automatic and one is manual.
Being I didn't see anyone else rooting from Verizon I took the time to figure out a manual method so i can verify each step and figure out issues if I ran in to any. With Superboot its either it works or it doesn't there is no playing with procedures.
This should work for other carriers to, I can only verify it for Verizon though.

I get past <adb reboot bootloader> just fine but then when I do a <fastboot oem unlock> it just says "waiting for device" forever. everything is installed but under my drivers it says;
"Android 1.0" drivers not installed.
plz someone help, ive searched all over the net but only found help for HTC phones and 2007 old posts.
edit: I am in "Fastboot mode"

Update the Samsung ADB driver under device manager while you are sitting in the bootloader. I'm bootlooping after pushing the boot.img

got it working, "Note: 1" under this guide fixed it.

thanks again XDA!!

GOod. Mine is still bootlooping back to the Google screen with a lock on it.
Booted into recovery, formatted. At least i can boot up now.

Sounds like you didn't successfully unlock your bootloader. Have you resolved this?

Done and rooted. Pushing APK's now.
I would recommend doing a full wipe first. I think something got corrupted during the forced wipe when unlocking.
After wiping, I started over. Unlocked and flashed the boot.img. Got a full normal reboot. Flashed it a second time, and it stayed at the google screen and i could connect to it with ADB. Pushed all the commands and rebooted. Works great.
Thank you.

I assume you need to have adb installed before doing this? Or do the command prompts perform from windows?

I had it previously installed. If you download the zip. its already in there, just run it right from the directory you unzip it from.

I would like to return my phone to stock. Locked, unrooted, and available for OTAs. Is there a way to do this yet?

After you complete that Run:
fastboot oem unlock
From the main instructions and simply relock it.

Stuck in an infinite loop

Model: GT-I9250T
Original Android version 4.04.
Root method: Gained root without having to unlock or overwrite the vanilla boot-loader and used OTA RootKeeper to backup su.
Long story short: My phone recently updated to 4.2.1 OTA. I restored root using OTA RootKeeper without issue. However when I went to restore The LBE Privacy app service, it caused my Nexus to enter a loop the moment it finishes booting and the lock screen appears.
Behavior:
After booting to the lock screen, the screen flashes and goes black then gets back to desktop and starts all over again in a loop. Once it does that about 3 or 4 times, it'll eventually get to a totally black screen except for the Android robot guy lying down with his belly open and an exclamation mark coming out. It'll then sit like that for about a minute and then the phone will reboot from scratch and the whole process repeats.
Apparently i'm not the only one either: url = badappreviews.com/apps/23315
From the linked site it looks like someone fixed it by using clockworkmod. However I don't see how that's possible as there is no way to enable usb debugging or copy any files to the sdcard as you can't boot the phone properly in the first place. I also noticed that I can no longer get into fastboot using the volume up and power button. However I can get into Odin mode.
Any ideas???

Install CWM or TWRP, wipe it clean, mount sdcard from there or adb sideload a ROM.

But how do I do that if I can't get usb debugging or get it connected to a computer or fastboot as mentioned?
Edit: nvm, looks like i am able to get into fastboot after all.Now here's hoping I can install it without having usb debugging enabled.

Just flash the android stock image through adb and go from there. You don't need debugging access when you're in fast boot
Have I helped? Don't forget to make love to that "Thanks" button!

Download stock images and flash em via fastboot, but you will lose everything. Its the freshest start you can get.
Sent from my Nexus Prime

Seriously, do you need to 'enable debugging' to be able to use adb in recovery?? It's a completely different and independent partition.
And fastboot doesn't need any enabling at all.
So, boot to recovery
mounts and storage
mount sd card
open up a DOS box (or terminal if you're on a mac or linux)
<path to adb>/adb shell
...
profit
The ... is where you go and uninstall the app/service, like the example you found mentioned above.
Usually this would be removing a .apk from either /system/app or /data/app

Thanks for all the help, however i am unable to get the adb drivers installed. I tried both Samsung's and Google's and they both fail (Windows doesn't even recongise a driver even after pointing it to: \sdk\extras\google\usb_driver. Anyone got any other sources for a working driver? Win7 64bit.
Edit: Managed to connect it using the pdanet drivers. Then proceeded to try to load CWM using: "fastboot flash recovery *file name*.img", but just got an error: "FAILED (remote: invalid argument)". I noticed that on my fastboot menu, it says lock state: Locked. Is this why it's failing? The boot loader is still locked? Because I tried "fastboot oem unlock" and that didn't work: "FAILED (unknown status code)".
Edit: Looks like my phone just needed a reboot. Because once I did, I was able to use the fastboot oem unlock command with success! However, before I proceed with unlocking the bootloader, can someone please confirm for me that I need to do so in order to install CWM? Many thanks.

Yes, but unless you have a play store gnex, this will probably wipe your phone anyway.

Problems rooting, adb etc.

Hello, I've tried rooting my Nexus 7 (2013) with LTE for like 5 hours now...
I've done every single thing in every single thread, and I still can't do ****.
I've tried the WugFresh root toolkit, but that did not work at all for me, I uninstalled and remove what they told me to do... But nothing worked, when I followed the WugFresh toolkit I lost usb mass storage... N7 did not appear at all on my computer, which it did, before I tried to screw with it...
I've tried doing it the manual way too, downloading all the drivers, uninstalling the other onces first.. But nothing... I could not even get the device listed in adb! I tried the full driver installation thing + automatic check if everything worked out, but the tablet would NOT run the script to reboot it into fastboot, and when I tried to restart the tablet into fastboot, and then continue to run the toolkit, it would start TWRP, the popup on my computer told me to flash something "!flashready", but I could not find it in the sdcard...
I unlocked the n7 manually, holding the volume button and power button down.
I know that was very bad written, but I'm a bit in a hurry. Anything I could do?

So the current condition of your device is that ADB is nonfunctional but you are able to temporarily boot into TWRP with fastboot - is this correct?

I'm not sure what this means. If you're using a toolkit, you're not doing it manually. Have you tried ADB and fastboot alone, without a toolkit? Is TWRP on your phone now? If so, you're done; just flash from recovery 1) a ROM for a custom ROM or 2) SuperSU.zip for just root.
If you don't have TWRP, does your Google boot screen has a locked icon at the bottom? If so: for ADB to work you need to have debugging turned on in your phone's developer settings. You don't need ADB though; just reboot into the bootloader by holding power and volume-down. Then type "fastboot devices" and see if anything shows up.
If it's an unlocked icon, just flash a recovery.img from fastboot.

The toolkit is using the command
Code:

to temporarily boot it over the stock recovery. Since you unlocked your bootloader manually, you can replace the stock recovery manually too using

Fastboot is separate from ADB. Your fastboot is working if the toolkit is able to boot TWRP.
Code:
fastboot devices
is what you use while your device is in the bootloader.

[Q] Am I bricked?

Please help! I am new to this and am worried I bricked my phone.
I successfully rooted my Verizon Samsung Galaxy Nexus using a toolkit. It was then working fine with 4.2.2. I wanted to install Shiny Rom 4.4.2. I thought I successfully backed up apps and data using Titanium Backup.
I successfully moved the correct zip files to my phone, and realized I needed Clockworkmod recovery. I followed a procedure to get this on my phone by using my computer's command prompt. I successfully booted into Clockworkmod recovery and followed the process of wiping data/factory reset, successfully installed radio and bootloader recommended to install with ShinyROM but got stuck and could not install the ShinyROM itself. I think it is because it requires a later version of Clockworkmod. The one I downloaded using the procedure was 5.5.0.4, but I think I need a later version. I tried following the same procedure using my computer's command prompt and it got stuck at "waiting for device". I cannot get out of Clockworkmod recovery now (even battery pull, etc.). I then found some threads saying I need to restore my old ROM first. (I think) the only ROM on my phone is ShinyROM. I am stuck and stressed out because I do not know of a way of "pushing" the new version of Clockworkmod to my phone.
Can I fix this, or do I need to start shopping?

i think u already wiped data partition at first, that why your Rom installation aborted bcoz recovery cant mount any partition.
still got your old system partition here.
from recovery ~ try adb sideload your shinyRom. can your pc detected bootloader (fastboot)/recovery?

Regarding partition, I have an option to wipe cache partition. Should I do this?
Update
Well, I went ahead and tried this, and still could not install ShinyROM.
I tried to follow a procedure in the link to use ADB sideload.
I downloaded (full) SDK and updates and updated the drivers. When I get to the following steps from the procedure...
-Boot your device in recovery mode (Android logo with a exclamation mark) and connect your device to PC
-Hold down "power" button first, followed quickly by "volume up" button. You should now see the recovery menu
I only boot to CWM and there is no Android with Exclamation mark. Holding down power button only selects whichever option is highlighted within CWM.
Also, it seems within CWM, there is supposed to be an option to sideload a zip file. This option does not exist in my version of CWM.

Thanks. I found another thread that led me to the same conclusion, except I was able to do it with CWM and fastboot the latest version using ADB sideload. I still haven't posted enough to link, but here were the details from user camblue.
"
If you know how to use ADB you can always fastboot a recovery.img,,,,this thing is almost impossible to truly brick. IN order to get into fastboot just connect to your computer and run adb with these commands
adb reboot bootloader
once in fastboot mode write this
fastboot devices
that will tell you if your device is connected and reading in fastboot mode if it is you will see something like fastboot and some numbers next to it. If nothing you do not" have the fastboot drivers installed.
then to fastboot flash a recovery.img write this
fastboot flash recovery r3-recovery-clockwork-touch-6.0.0.4-nexus7-modaco.img (or whatever recovery.img you are using or have in your tools folder of you SDK location).
and in order to get right into CWM if you cant boot write this
fastboot boot r3-recovery-clockwork-touch-6.0.0.4-nexus7-modaco.img
hope that helps

[HOW-TO] Root the Shield TV

First of all, let me say this isn't my post, and I didn't develop this method. The user, "Teletype" got this all figured out and did an amazing write-up for it. I'm posting it on their behalf so it can be in this newly added forum. The link to the recovery zip is also in his original thread, which I've linked below.
Here's the link to his original thread. If you feel the urge to press "thanks", please go to his original thread and press it for him, he deserves all the credit.
teletype said:
I just managed to get TWRP running on the new Shield console, and installed SuperSU successfully. Two caveats: the display is upside down, and the USB host ports don't work. I had to plugin a mouse via an OTG cable in order to interact with it. ETA: That's only an issue when booted to TWRP. Everything's working fine in the stock ROM after rooting.
Procedure:
- enable developer tools / USB debugging
- adb push supersu.zip /sdcard
- adb reboot bootloader
- fastboot oem unlock
- fastboot boot twrp-2.8.6.0-shieldtv-unofficial.img
- unplug USB cable, connect mouse via USB, install SuperSU
TWRP boot image is attached. Off to explore...
EDIT: by request, some more detailed instructions:
On the Shield device, head to Settings -> About, and click "Build number" 7 times. This will enable Android's Developer options.
Go to Settings -> Developer options, and enable USB debugging.
Install the ADB/fastboot drivers and utilities if you don't already have them. When "adb devices" shows your Shield, you're good to go.
Download and extract recovery.zip from this thread.
Head to the SuperSU forum and download the latest version.
Open a command prompt and navigate to the directory where you downloaded everything. (Google this for your OS if you don't know how).
With the Shield still booted, run "adb push supersu.zip /sdcard" (change supersu.zip to appropriate file name). This will upload the SuperSU update zip to your device, which you'll install from TWRP.
If that worked fine, run "adb reboot bootloader". Your device should shut down, and display the Fastboot screen after a few seconds.
FOLLOW THE NEXT THREE INSTRUCTIONS AT YOUR OWN RISK. This WILL wipe all your user data, back it up with ADB first if you want to preserve it. DISCLAIMER #2: I have no idea if there are any DRM keys or anything that get wiped when this is done (this was the case on my Xperia Z3 Compact). I will say that Grid streaming still works fine after doing this.
This step will unlock your bootloader to enable booting unsigned images.
Run "fastboot devices" and make sure your Shield is visible.
Run "fastboot oem unlock" and follow the prompts on the screen. Your bootloader is now unlocked.
Now, boot the TWRP image with: "fastboot boot twrp-2.8.6.0-shieldtv-unofficial.img" - Note: I used this instead of "fastboot flash" so I could keep the stock recovery around, to grab an image of it after rooting.
You should now see a TWRP recovery menu (upside down for now).
Connect a keyboard or mouse via OTG cable, and select "Install", navigate to your SuperSU zip, select it, and follow the prompts.
Click "reboot" and you should now be rooted.

does this have to be done with an otg cable

You can use the supplied micro USB cable to do the adb portion. You shouldn't ever need otg with this device since it also has 2 full sized USB ports.

Instructions got updated
Hi,
I have updated the instructions to ones that more closely aligned with my experience of doing this. The initial instructions were good for me - but some were in slightly the wrong order or not quite clear enough to be immediately intuitive. I've tried to fix that Hope it helps.
On the Shield device, head to Settings -> About, and click "Build number" 7 times. This will enable Android's Developer options.
Exit settings, then go back in to settings -> Developer options, and enable USB debugging.
Install the ADB/fastboot drivers and utilities on to your PC if you don't already have them. When "adb devices" shows your Shield, you're good to go.
Download the latest Super user zip file from the super user thread here.
Download and extract the recovery file from here. (it needs to be a .img not a .zip)
run "adb reboot bootloader". Your device should shut down, and display the Fastboot screen after a few seconds.
FOLLOW THE NEXT THREE INSTRUCTIONS AT YOUR OWN RISK. This WILL wipe all your user data, back it up with ADB first if you want to preserve it. DISCLAIMER #2: I have no idea if there are any DRM keys or anything that get wiped when this is done.
This step will unlock your bootloader to enable booting unsigned images.
Run "fastboot devices" and make sure your Shield is listed when you do so.
Run "fastboot oem unlock" and follow the prompts on the Shield's screen. You use the power button on the shield device itself to navigate the menu, and long press to select an option. Once you have confirmed, this can take along time to unlock (hour and a half for me on the Pro version). Your bootloader is now unlocked.
"Fastboot reboot" to reboot to AndroidTV.
run "adb push supersu.zip /sdcard/" (change supersu.zip to appropriate file name that you downloaded earlier). This will upload the SuperSU update zip to your device, which you'll install from TWRP.
Now, boot the TWRP image with: "fastboot boot RECOVERYFILENAME.img" - Note: I used this instead of "fastboot flash" so I could keep the stock recovery around, to grab an image of it after rooting. (change the name of the file in the instructions to the name of your recovery file that you downloaded).
After a short while you should now see a TWRP recovery menu.
Connect a keyboard or mouse via OTG cable, and select "Install", navigate to your SuperSU zip, select it, and follow the prompts.
Click "reboot" and you should now be rooted.

Anyone tried kingroot?

We have a factory supported way to unlock and root. No real point in trying to exploit the system. If you are rooted, you should have a custom recovery anyway, which means you need to unlock the bootloader anyway in case you need to fix something.

Hey, I have rooted my shield and I didn't backup my stock recovery, anyone have a stock recovery img, I want to update to 1.4
Thanks

You can download the 1.4 firmware and flash it manually. There's a discussion on it a few pages back :good:

You'll get the OTA notification but I was not able to install the OTA. You will need to download and new firmware and flash from fastboot.

Can I still root it this way if I already updated to 1.4 as I'm still fully stock and took the OTA

Im asking the same, im on the latest as of 2015 10 19, can i root using this method ?

You're guided imagery? I read without understanding very much

Can anyone confirm this rooting method works for new firmware 2.1?

I struggled to get root with this write up, and I am not a rookie. There were a few key steps missing, for example, you actually have to flash twrp, you can't just boot from twrp as suggested, if you are on 1.4 and up. Also, you have to let the unit reboot after you do the OEM unlock before flashing twrp. I didn't and mine just froze after flashing the recovery img. I found this write up http://nvidiashieldzone.com/index.php/shield-android-tv/root-shield-android-tv/
That one in the shield zone forum was so much more complete. And yes, it worked just fine with the 2.1 update. I did it yesterday with no problems. It will wipe out your data, and it will take a long time after you do the fastboot oem unlock, especially if you have the PRO version. But root is working with no problems.

First of all, let me say this isn't my post, and I didn't develop this method. The user, "Teletype" got this all figured out and did an amazing write-up for it. I'm posting it on their behalf so it can be in this newly added forum. The link to the recovery zip is also in his original thread, which I've linked below.
Here's the link to his original thread. If you feel the urge to press "thanks", please go to his original thread and press it for him, he deserves all the credit.

Do you want to build pre-root shiled TV firmware by nvidia open source？ and have experience？

Rooting.
KingRoot dose not work on this device.

Good guide thanks.

OK i have a 16gb model on 2.1, got adb hooked up but get this when trying to push supersu.zip to sdcard0:
C:\shield>adb push supersu.zip /sdcard1
failed to copy 'supersu.zip' to '/sdcard1': Read-only file system
Any ideas?
