Worked for me too! Thanks man!
For anyone else looking for a solution to this problem where the battery replacement doesn't work, such as a busted volume down button or something...
IF you can get the phone started at all, you can use the ADB shell to reboot into recovery.
Now you might have other issues after that if you can't use certain buttons to navigate the bootloader menu. But if for example you just want to return the device to stock for a warranty exchange and you have a bad volume down button, you can reboot into recovery using ADB then you should only need your volume UP button to initiate the flashing of the PD15IMG file.
So there's limited usage for this technique, but it'll work wonders when you need it.
Power off the phone and reboot into the bootloader by holding VOL DOWN + POWER until it boots to the white screen.
It should check the PC36IMG.zip and then ask you YES/NO to apply the update. Press VOL UP for YES
Once complete, Press VOL UP to reboot.
You are now unrooted!
ok i know all this but i cant see can someone give me a time line when it says update

This doesn't unroot your phone. This is the method to flash amon ra recovery.

O may be wrong buy I think a ruu runs just like a splash or recovery via pc36img.zip
sent from my HTC evolution running a freshly baked gingerbread with the 4gs in it
Yes you can use the ruu with the most recent update which will remove root. But it will not set you as S-Off.
Are you looking to turn S-On?
Haii so im trying to install a rom and i cant do it. Everytime i choose to go to recovery mode it just stays in a black screen and the only way is to remove battery and restart. Thanks for your help

While phone is off..hold vol down + power. You will enter the bootloader..with the volume button highlight recovery, press power button. Also have you flashed a custom recovery?

i recently rebooted my Vodaphone AU and was presented with a hboot menu. i have tried to navigate up and down this menu but the screen is frozen so cannot select any of the options. i turned my phone off by removing battery as power button was also inactive. i then powered back up and straight to hboot screen again, again all buttons inactive so cannot navigate up and down or select. removed battery and sd card then tried again, this time holding down volume button whilst powering up. still i have no joy, phone will not let me navigate or selct in boot menu and everytime i power down and up it is the same scenario. this is the message i have above boot menu.

Please can you give advice how to fix this.
Try going into adb and see if you can reboot from there, not to sure.what to can do really

Unfortunately it sounds like a hardware issue. Could be simply that the volume rocker is stuck or it has to be replaced.
Adb doesn't work in boot but fast boot does.
On my mothers old phone it would do the same and only way I could get it to boot was to run
Fastboot reboot
So you can try that but I would try carefully moving to volume rocker and see if stuck

Thanks, sounds reasonable.
Have ordered a new volume flex cable/board.
Tried booting holding down the volume down button and power simultaneously and am able to select recovery mode but I just get a screen with the white Google name - recovery mode never starts (I have waited minutes) and I have to hold down the power button to get back to a normal startup. Also tried connecting to my PC via USB and booting holding down the power and the volume up and down buttons simultaneously. Then I get the belly-up Android and the Start selection but the volume keys don't change the selection and the power button does not cause a start - I have to power down by holding the power button in and restart normally. Any ideas?

You can use one of the root tool to reflash recovery mode if you don't know how to use ADB (which I don't really know.) You can flash CWM or TWKP or whatever it is. Then you should be able to do whatever you need to do. I have used the galaxy nexus tool kit v7.0.
Connect to pc
Shut down nexus 7
Hold volume down and power
At the next screen, press up until it says recovery mode
Press power
You then get the Android with red exclamation
Press power, hold it and then press volume up
This should give the recovery menu.
Result!

As I noted, I tried this and at the "At the next screen, press up until it says recovery mode" point, when I press the volume up button nothing happens, it stays with Start displayed (and pressing Power at that point has no effect - I have to press and hold Power for many seconds to force a shutdown).

You need to press volume up a few times, until you see Recovery.
This guide worked for me, so thanks AMoosa.

Yes, I said I tried that and pressing volume up has no effect - it stays at "Start" and even pressing Power at that point has no effect, I have to press and hold power to force a full shutdown.
Same problem here. A full stock re flash didn't help either.

Could you do anything more after rooting?
sikagoon7 said:
That is normal. If you press power and volume up you should get a recovery menu. It is pretty featureless so I assume you were expecting the likes of CWM or TWRP. These are custom recoveries that you need to download. To install them you need to unlock the bootloader and either manually flash them via fastboot or by using an application like goo manager or rommanager. Note that the application method requires root.

I think he has the same problem I do. "If you press power and volume up you should get a recovery menu."- I can't get to the recovery menu.

Manually load 4.1.2 --
http://www.androidcentral.com/how-manually-update-your-nexus-7-android-412
One update - I could get to recovery using adb (adb reboot recovery) but once there adb could no longer see the Nexus (adb devices showed null). Have to try some more when I get home from work tonight.
Manual update to 4.1.2 is original reason for doing this but now I'd like to understand why I can't get to recovery mode the "standard" way.
sikagoon7 said:
You are getting in the standard way. Flash a custom recovery now to use it.

I meant through the menu selection on the Nexus itself, not through adb. And as I noted, once I got to the recovery screen, adb could no longer see the device.

Again that is normal.

Well, with 4.1.2 (OTA) I can now get to the recovery screen by using the simultaneous power + volume button pushes, no adb required.
sikagoon7 said:
Is that's what you were looking for? The side load menu? I thought you were saying recovery didn't work. Recovery has to work for you to even use the power volume up trick.

Adb was never required to get to recovery. That's the bootloader's job.

On the final set of workaround instructions, it says "4. Select Recovery using vol buttons and press power button" - I could not "Select Recovery" because at that point my Nexus would not respond to any button pushes.
Install latest nexus 7 bootloader from my dropbox.

This fixes the boot loader bug and now you can enter recovery from the bootloader screen.

Update the bootloader to 3.41. Make sure NOT TO DELETE THE BOOTLOADER!!!!!!!!!!!!!
I cannot emphasize this enough!!!!!!!!!!! I bricked my first one this way.
Use fastboot flash bootloader C:\>>>>>>\bootloader-grouper-3.14.IMG
Do NOT erase bootloader before you flash the new one. And after you have flashed the new one type; fastboot reboot bootloader and check the bootloader version to make sure you succeeded.
Good luck!

Though a series of misadventures I now have the saem problem as the OP of this thread where i can no longer get myself into recovery mode.
I had just doen a full backup and flashed a new version of the kernel when this occurred. Please don't tll me to use my volume keys to select Recovery. As the OP said, the keys no longer work. Theydid once but no longer. My N7 is stuck on the picture of Andy belly-up with Start shown but I cannot scroll up or down nor hit the power key to Start.
I download the file from two posts up but not sure what to do from there. FYI, I was fairly familiar with the ins and outs of Andoird, ADB, etc a year ago when developing apps but I've since retired. DO I need to get the downloaded file onto my device in order to use ADB to perform the fastboot commands above? Could someone please enumerate the steps for me to give me a jumpstart?
Edit: Whew! I got a tip to use Mskips' nexus 7 toolkit and got back into recovery and restored my backup and all is well so far. Knock...knock

After the Android with red exclamation mark, the keys don't work. I press the power + volUp button and the device just reboots!

I have the same--or at least a very similar--problem. I was trying to flash it back to the factory default with Nexus 7 toolkit. In the middle of the process my computer froze and I was forced to reboot. Now when I try to enter recovery I get a tiny "booting failed" in the upper left corner of the screen and nothing more. I can't see my N7 with my computer via USB or adb. I'm at a loss. Any suggestions?
Exacty what happens to me. Trying to manually upgrade to 4.2 without root. I have update.zip on my n7. Do I need usb to be plugged into pc? I tried it both ways... when usb was plugged in I got past the red explanation mark, with option to install from adb, but not from sd. If not connected, nothing past explanation mark.
Probably just wait for ota... don't want to mess anything up.
