Hi,
I bought the GNexus a month ago, its my 1st android device. (I had a Blackberry for the last 3 years).
I have unlocked my Gnex, and rooted it, then i have installed yakju in order to get rid of my yakjuux ROM, it was my 1st time doing it... Everything worked fine, all my apps were automatically redownloaded and reinstalled from my google account. (Very nice feature).
But for some reason now, I have lost my root acces and I am not sure why or how.. is it normal? I have installed root checker, and supser user returns messages saying he cant get root privileges on my phone.
I tried rooting the phone using superboot. Everyting seemd to have worked fine:
C:\Nexus\r3-galaxynexus-superboot\r3-galaxynexus-superboot>install-superboot-win
dows.bat
C:\Nexus\r3-galaxynexus-superboot\r3-galaxynexus-superboot>fastboot-windows.exe
boot boot.superboot.img
downloading 'boot.img'... OKAY
booting... OKAY
The phone reboted but stayed at the Google logo for like 3 mins. I pulled the battery and after that the phone rebooted normally except superuser cant access root.
Any tips or help is welcome on how to root the phone (already unlocked)
Thanks
You should have left it on there! Mine got stuck on the Google boot logo for around 10 minutes before it was done? I was just about to pull it before it booted up. Go through the process again and give it time

Go on YouTube and look for zedomax. He has an easy root video with a link to all the software

when you installed the yakju ROM to change yakjuux it deleted root because you fully wiped your phone for a yakju build. just reapply superboot (or install clockwork recovery and flash su.zip that will give you root) and you'll have root.
either that or flash a custom ROM with clockwork recovery and you'll have root.
Another thing is always make a backup of your current favorite rom before flashing anything. I have my original rom and 1 favorite rooted rom on backup at all times. If you do this and encounter problems you can always go in recovery and restore your custom rooted rom. The only reason I keep a stock rom on is in case I have to return the phone. You can remove your unlock symbol by going in fastboot and typing (fastboot OEM lock) I think! This was how I locked my bootloaders back up on my beloved nexus s, good luck and pm me if you need anything

Didn't know about su.zip option in CWM, where can I find this zip file for the GNex GSM?

I gave it like 30 mins and still the Google logo was displayed. It seems my rooting did not work properly. Maybe i am not using the right tools?
Zedomax has a nicve procedure, but the link to doenload is GalaxyNexusRoot.zip file is dead. I cant use his method..
Thanks for the help.

I couldn't find it on XDA but I did get it off XDA before and have tested it on 4.0.2 when I used 4.0.2 stock. I just uploaded it: http://www.mediafire.com/download.php?4qq8mhu7w0437ky flash in cwr.

Hey, if anyhow could help that would be great. I followed ask the instructions to flash Clockwork mod on my t999. Odin recognized phone, i pda'd clockworkmod.tar file, it passed and rebooted. Then i held power up+home+power and entered Android system recovery. Have done a few times and i continue to get Android system recovery. Obviously my phone isn't rooted yet, just got it. Is there an alternate way to get clockwork mod or am i doing something wrong? Thank you, any help is much appreciated...

So if you know a way i can root my phone without being clockworkmod, can you paste a link? Because it's telling me i need clockworkmod to root phone....thanks again

Have you installed recent LH2 OTA update? This is a known issue with this update,quite well described here. To root your phone, you should flash CWM with ODIN, then don't let the phone boot normally (by pulling out the battery), then boot in CWM once and flash root. Finally, after booting the phone normally, CWM will be rewritten, but you will have rooted phone. Hope this helps.
There's another really helpful tutorial on rooting without tripping the flash counter. It's stickied around here somewhere, I'll see if I can find it.

By the way, it worked perfectly, i suggest though, when in Odin, uncheck auto reboot, so it didn't reboot after it passes, then i just pulled battery out and tried booting in CWM and it worked. Guess you can't let it reboot or you have to do it again. My last question is, do i keep my phone in usb debugging mode with root on stock rom? I had a galaxy s2 and i know some custom roms had to have usb debugging on. Just not sure if stock with root i should or shouldn't. Thanks again, i hit all the thanks meters on this one, was driving me nuts....Jake

I use TRWP is a better recovery for sg3
I flashed CM10 onto my phone a couple weeks ago, everything went smoothly. Today, I reverted back to stock and locked the bootloader so that I could receive the stock JellyBean update. Well I download the update, reboot phone into fastboot, attempt to go into recovery and I get the red triangle !. I know this is an issue with the phone apparently not finding a recovery boot but why didn't my reverting to stock reinstall the stock recovery? Does anyone have any guides they suggest to get stock recovery back? (I've found a few but thought I would ask).
Now, this is understandable that my phone can't boot into recovery since I flashed CM recovery onto it and whatnot, but I attempted to boot into recovery on my girlfriends phone (same phone, NEVER BEEN UNLOCKED OR FLASHED) and it can't boot into recovery either... Is something going on here or am I just missing a huge piece of the puzzle? I don't really want to have to flash anything on my girlfriends phone to fix it, she's not into the tinkering and would rather not have her data reset. Any help would be appreciated.
And for the record, I did a search to figure this out but at the very least I can only find solutions for people who have flashed CM or similar and nothing pertaining to the problem my girlfriend's phone has.
Tried reflashing recovery already? How did you "revert" to stock?

It worked, I'm on stock ICS, but I didn't do ANYTHING after booting into ICS again and attempting to install JB and booting into recovery. Did I miss something? How do I "flash recovery"?
Unzip the factory image you get from developers.google.com/android/nexus/images
Then use fastboot to flash the recovery.
EDIT: red triangle doesn't necessarily mean the recovery is broken. It's just the way it is. If you wish to flash a 3rd party ROM you'll need to flash a 3rd party recovery.

I think you are confusing a few things here. First off, the Android with the red triangle IS the stock recovery main screen. (If you want to flash the update manually, you need CWM -- go into fastboot mode and type: fastboot flash name-of-recovery.img, where name-of-recovery is the recovery that you downloaded and want to flash.) Second, you need the stock recovery for an update to install over-the-air, but you need a custom recovery if you want to flash it manually.

this happened. you installed stock recovery when you reverted, whats the surprise?
and you dont need to relock bootloader to successfully update through ota. seems to me know the op needs to refine his searching skills.

So in the context of my girlfriend's phone where nothing has been done to it in the 4 months she's had it, why would it be giving the recovery error? Also, does flashing the recovery wipe the phone?
It's funny too because I just got the JB OTA but I'd still like to get this figured out.

run the update manually (found on the Update link on efrants sig) through cwm, that should give you a more detailed description of whats going on.
flashing a recovery doesn't wipe the device. unlocking will, btw. its not an error, its the stock recovery!

Alright, I think I got it... so the android with the red ! triangle IS stock recovery? I just remember on my Nexus S being able to boot into recovery and load up a stock .zip update manually without any custom recovery mod. Is this not possible on the Galaxy Nexus then? So what does the stock recovery DO other than sit there and reboot after a minute?

Thank you! I feel like an idiot now. I honestly thought it'd be the same as the Nexus S where you were able to do this...
So in the rush to get CyanogenMod installed on my newly-S-Offed phone, I downloaded CWM from the appstore and started looking through the various devices to flash ClockWorkMod Recovery to. I selected the vanilla HTC One, not the verizon-specific model. I have not yet rebooted my phone yet, but I am worried that doing so will brick the phone since I technically don't have the right bootloader. Looking through CWM's list on my phone, there is not a verizon-specific model bootloader. There is one on Cyanogen's site (can't post the link due to XDA restrictions), but it appears to involve rebooting the phone. How should I go about safely flashing a good bootloader onto my phone?

CWM is a custom recovery, not bootloader. Download your choice of CWM or TWRP, reboot into the bootloader and use Fastboot to flash it.

I am referring to ROM Manager from the android app store. When you bring it up it asks you to flash your bootloader. The bootloader I selected was the one for the Vanilla HTC One.
I don't use ROM Manager, but I just installed it on my phone. The prompts all refer to recovery, and make no mention of bootloader. See below.

Its most likely referring to the recovery, not the bootloader; Assuming you're root, Rom Manager is there to flash custom ROMS and custom recoveries. I don't think you'll have bricked your phone if you installed a bad recovery, but I think your best bet would be install a compatible one manually.
SO pick a thread and follow the directions under installation:

Well my phone will reboot safely, which is good.
However, rebooting into fastboot or recovery just reboots into normal mode. Recovery will say the first time that it's going into recovery, but will reboot again and go into normal.
Thoughts?
Success! I just had to keep scrolling. there was a version in Rom Manager, all the way down at the bottom under "m7vzw." Flashing that did the trick.
Thanks for the help.
Cheers.

The S-Off exploit removes stock recovery, so it will go nowhere until you flash CWM or TWRP. Fastboot will work regardless.

All that said, I can now boot into recovery no problem, but typing "adb reboot fastboot" just reboots the phone normally. Any idea why that might be?
I've never used that command personally. I have Quick Boot (Reboot) from the market and use it for getting into recovery and fastboot from Android.

Do you have fastboot unchecked under power settings? Phone doesn't totally reboot with that checked.

adb reboot recovery = takes you to recovery
adb reboot bootloader = takes you to fastboot/booloader
I don't believe adb reboot fastboot is a command, so it just does adb reboot
So I got an adapter (Finally) for my nexus 5x. Went home and got the WugFresh nexus toolkit. Made a backup, and things were going fine, and then hit root and install twrp. It installed and booted into twrp, and it gave me the not rooted message and rooted me. I restored the backup. So I rebooted it, saw it was doing the boot animation, and came back this morning to it being dead (I had it plugged into my desktop, thought it wouldn't have lost more than 1% of battery when I woke up). I tried booting it up, and it was booting forever and I concluded was bootlooped. Now, when I try to boot into recovery, I get the little android guy dead with the red triangle on top of him. Please help, I'm 14 and don't really know what to do because all my previous rootings went fine. Thanks!
You are on stock recovery. Flash TWRP if you want custom recovery and flash/wipe, or use the factory images to go back to stock. Any experience with adb and fastboot? I'd recommend using fastboot so you have an idea of what's going on and understand how to fix your phone in the future.

I know fully well about adb and fastboot. I've rooted all my phones before this manually via them, and i just tried the toolkit because a friend referred it to me. Like i mentioned before i'm in a bootloop and i have no access to it in adb. It just doesn't get recognized.
Hold power + volume down till you boot into the bootloader. Flash away.

yeah when i try and boot into recovery is when i get the red triangle above the android guy. there is literally no recovery there. Otherwise, yeah i would flash the firmware
Help!!! My Nexus device is totally messed up. It has ______ problem. What do I do?? @ wugfresh.com since you're already using that toolkit.
if your pc/NRT doesn't recognize your phone check the drivers and consider reinstalling them (the toolkit apparently has an option for that as well). also try playing around with the rotation of your adapter/cable. yes, usb c is supposed to work both ways, but some (cheap) cables seems to have different properties depending on the rotation.

There is, its just the stock recovery. Go to the bootloader and flash TWRP using fastboot. If you have driver issues you might have to manually select the driver I normally have to the first time.
