As with any stock update, the JB update disables root access and replaces whatever recovery you have with the stock recovery.
The only way to root is with an unlocked bootloader. So:
1) Unlock your bootloader;
2) Flash CWM using fastboot;
3) Flash a superuser zip to get root;
4) Boot into Android;
5) Use a file explorer with root access to delete these files: /system/etc/install-recovery.sh and /system/recovery-from-boot.p
6) Re-flash CWM;
7) Done.

[Q] help

Successfully rooted my phone yesterday, but was unable to flash Android 2.2. After fastboot checks pc36img it just goes back to fastboot screen. Was there a problem with unrevoked3 or clockworkmod?
If you are trying to flash a rom, you need to do that from recovery. What exactly have you done to your phone so far, which root method did you use?
I used the method for rooting Eco 4g with Android 2.2 I rooted the phone through to Android 2.1 then with unrevoked3 then copied clockworkmod files to the sdcard
But have u actually installed a recovery yet? You have to push a recovery through ADB or use a terminal emulator.

I thought clockworkmod was a recovery when I go into recovery it is a clockworkmod version

So you have root, you have your recovery, what is it you are trying to do now?

Yes but more so the update zip I think the recovery flashed correctly, the guide says to go to hboot and the phone checks for pc36img, but once it does instead of asking me if I want to apply update it just go back to fastboot
If you're already rooted why r u trying to flash a pc36 image?

Trying to flash 2.2 root I'm on Android 2.1 now
You don't need to flash PC136.img to get android 2.2. If you're fully rooted with recovery you can flash any ROM that uses Froyo and you'll have 2.2

You don't flash a rom with a pc36img. Download your 2.2 rooted rom and place it on the root directory of your SD card. Also,make sure you delete the pc36img on your card so your phone doesnt keep searching for it later. Turn the phone off. Boot into recovery by holding down volume and power at the same until until the white bootloader screen appears. Select recovery. Then select wipe/factory reset, then select wipe cache. Then select install zip from SD card. Scroll to your rom and select it, confirm yes when it asks, and wait for it to finish flashing. Once it's done it will say install complete. Then select reboot system now. Your done.

Do you have a Rom you recommend and rooting method aside how would i install it
Here is a list of ROMs:

I'm starting to get confused here.....
1. Are you sure that you're rooted?
2. Are you sure you have successfully flashed a recovery?
3. Have you copied the .zip of the ROM you want to flash to the root of your SD card and booted in to recovery and tried to flash the .zip?
Sorry for the confusion, but I'm new to this, I'm positive I'm rooted and that I have clockworkmod recovery installed. I copied 2.2 root zip from my desktop to the root of my sdcard along with the pc36img and busybox. All three where part of the download link from the guide
Where is this guide at that you are following? If we can see where you are at, then maybe we can help get you back on track with what you are trying to do.

I assume you're at this part of part 2?
Step 3: After choosing NO to the reboot, you will see a menu again. Select Bootloader from the menu, then use the Volume Down button to hover over "Recovery" and press Power to click on it.
If your phone gets stuck at the White EVO 4G screen, pull your battery, and then power on while holding volume down again. It should boot to the bootloader again, where you can select recovery.
Once you are booted into this custom recovery, go to
It's supposed to go back to your menu (the white menu with the 3 green androids on skateboards) after scanning the PC36.img This is where you boot in to "recovery" Once in recovery, you can flash the 2.2.zip I have to say I've never used Clockwork so I'm not exactly sure if it's all the same menu. I've always used AmonRA
Not sure how i'm tucking it up, but the phone doesn't ask me if I want to reboot or if I want to apply the update what I do know is that if choose recovery and flash 2.2 it says install complete, but when I boot up i'm still in 2.1

Bootloader Relocks Automaticly

I'm having an issue with my friend's GN,
He suffers from random reboots which automatically restore the phone information to a specific date in the past.
I tried the toolkit, manual root and unlock but no luck.
the bootloader itself relocks itself right after i try the "fastboot reboot-bootloader" command.
I cant flash CWM permanently.
Can this be the recovery partition kicking in? I tried renaming it and I didn't get an error.
I managed to root the device, but then I cant install any programs from the Market, I was trying to get Root Explorer to work to ensure that the recovery is renamed or removed.
Whenever I flash the bootloader to primela03 it goes back primekk15.
Is this a GSM GNex (i9250)?
i9250
To me it sound like you actually never unlocked the bootloader in the first place..
Edit: To be more constructive... I have no idea what "the toolkit" does or how it works.
To unlock your bootloader you boot into it and run "fastboot oem unlock". That's the whole process. I personally don't see the value of a toolkit obscuring that process.
Unlocking your bootloader will cause your phone to factory reset and wipe everything on it. Have you done this? Have your phone asked you to confirm this? Did you click the volume-rockers to "yes" and then confirm with the power-button? And then, did the phone get wiped?
If you cannot answer "yes" to every question asked above, you have not unlocked the bootloader. End of story.
When you boot the phone up there should also be an unlocked lock icon under the Google logo at the bottom of the screen.
This is a wacky situation,
I tried using GNex toolkit 6 (http://forum.xda-developers.com/showthread.php?t=1392310) and it never worked.
"fastboot oem unlock" unlocks the device, but the as soon as I try "fastboot reboot-bootloader" it goes back to it's locked state.
I tried flashing another bootloader right after I unlocked it, but it reverted to the old one after rebooting.

Strange
There is a file that will put the stock recovery back when you reboot. I'm not sure what else that file does but maybe that's your problem?
Going from memory, I think the process is unlock via fast boot, flash clockwork recovery, boot into recovery, flash super user, I also removed that recovery file at this stage via adb even though other directions have you do it later with root explorer. And that was it. If you do it the way others wrote it up (using root explorer) you'll have to reflash the recovery again.

Here's what I just did:
1- Unlocked the recovery
2- Booted insecure image
3- pushed superuser
4- installed root explorer, ROM Manager via adb
5- in root explorer I deleted recovery-from-boot.p from /system and it came back then tried "adb shell rm /system/recovery-from-boot.p" and it's gone.
6- Tried downloading CWM from ROM manager and the phone reboots whenever it starts download and goes back to stock
rebooted and the damn thing still living in the past!!! even the recovery file is back!

You have to go back in and re-apply the recovery. That file "recovery-from-boot.p" is like a "reset" file that puts the stock recovery back during the boot process. I suspect it may be re-locking your bootloader too, but this is just a guess.
After you do step 5, repeat steps 1 and 2.

When you "Unlock the recovery," do you mean you flash a custom recovery or do you mean you unlock the *bootloader*? It's not the same thing.

O_O
the only thing I can think of is a hardware problem is causing the device to do a hard reset every time you boot.

Did that, the moment I reboot, everything goes back to normal :s
I'm also unable to wipe from the normal system settings, the phone reboots when we try that.
can it be related to this issue? http://www.galaxynexusforum.com/forum/rescue-squad/4093-data-not-wiping-cant-return-stock-3.html
If you have problems doing data wipe/factory reset, it's quite possible that storage is corrupted/failing. It may be whats causing all the random reboots and reverting to old info. Best to bring to a samsung center and make that warranty claim.
I'm not sure what you're doing wrong... but its something.
You shouldn't have to flash another boot loader. I'm not sure what you would gain from that with the phone being a nexus?
Flashing another recovery is necessary for flashing different roms, kernels, mods, root, etc.
If you are indeed flashing a different boot loader, may i ask why?

Don't just delete the file recovery-from-boot.p, as there's one more file that can do bad things. It's called "install-recovery.sh" and is to be found within /system/etc

Actually, don't delete either file.
Don't touch recovery-from-boot.p at all, and rename the sh.
If you want to be able to install otas in the future, renaming the patch file will break the MD5 check. The file is harmless if the sh file is out of commission.

Why would you temp root? Why not just temp boot to recovery, flash the superuser zip, and then restart. You'll be rooted, and if you don't want CWM installed, since it is only temp flashed, it'll disappear as soon as you restart.

I'm just following the process for the 4.0.4 install. How else can i do what i need? I'm quite new to my Nexus, i had a bionic before.
Thanks
Need the temp root to run mempodroid i think, can i do this another way? i honestly don't know
If you are on stock 4.0.2 (ICL53F), download the 4.0.4 OTA update zip that is posted here somewhere and put it on the root of the internal sdcard. Restart your phone into recovery (should be stock recovery) and apply the update. It will verify the system and flash the update if everything checks out.
From there, if you want to be rooted too, download the superuser package from http://androidsu.com/superuser/ and put it on the internal sdcard (location doesn't matter). Use fastboot to temp boot to recovery, you'll need a custom recovery file for this (CWM, CWM Touch, TWRP, etc.). Run fastboot boot <recovery image file> and it will boot into recovery. Select the option to install a zip file, flash the superuser zip you downloaded, then restart and you should be on stock rooted.

Which CWM version do i want and will this include the radios if i do it this way, sorry kinda newb at this phone. very different to my bionic.
Thanks so much for your help tho

I got into stock recovery and saw the android with the explanation point but when i click Volume up + power i get no menu...
I'm off to bed will check back in the morning and see if you have any ideas, thanks again for the help
Finally got the stock recovery to work, however it only allows flashing from ./cache and i cant get my update.zip to cache without root right?
So decided to just unlock bootloader and then it let me root and push to ./cache and then i flashed the update.zip
All seems to be working now.
Thanks for all the help
I love the fact its so easy to unlock and lock the bootloader. very happy with that lol
is there a way to re root the phone once its on 4.0.4 IMM76K ? as the Galaxy Nexus toolkit stops at IMM30B...
Thanks

You should *always* flash a superuser package (I used JB-SuperSU.zip) immediately after flashing a stock update - no reboot in-between! The stock update overwrites your recovery, so if you don't do it first thing you won't have another chance.
You're going to have to get to a computer with fastboot and reflash the custom recovery of your choice via fastboot, then boot into the custom recovery and flash a superuser.zip of some nature. You'll also want to delete /system/etc/install-recovery.sh (via adb or a file manager if your custom recovery supports it) before booting the ROM again or else your recovery will be overwritten again.

What Jellybean? Stock? Custom ROM? What?
If you installed a stock Jellybean image, you won't have CWM anymore, you'll have the stock recovery (Android with red "!"). If you have a custom ROM, you should have CWM still.
with a root explorer app, go to /system and rename recovery-from-boot.p to recovery-from-boot.bak and flash CWM again.
