Hello,
For the past week, I've been sifting through the forums looking for a solution to my problem. I have tried the Google Nexus Toolkit and others without success.
Last week, I was running a backup with CW and I MUST have pressed a button by accident. My Nexus 7 has been in the Google Lock screen and will not boot into anything. Power and volume etc... Just goes back to this screen. (see the enclosure).
I was rooted and havent flashed anything to it. I even tried stock cables and others.
Any help would be appreciated!!
Thanks in Advance,
Marty
You can't boot into the bootloader? When you can see that google lock screen, hold the power and volume down buttons. The screen should turn off, continue holding them. And when it turns back on, it should be in the bootloader, and you can let go of the buttons. From there the Nexus 7 Toolkit should work, the fastboot commands at least. Try reflashing a recovery if you can't get back into it, and flashing a rom, stock or otherwise.
Solved Thank You

Thank you very much!!
Not a problem at all, just ask if you need anymore help with anything.
hey
i got my new nexus 7 and wanted to flash a new rom, so i just downloaded this and the flashing tool from this thread.
i didnt root/unlock bootloader or anything else, i just used the tool and did all the steps.
Boot into fastboot,
Wipe my Data,
Install Recovery + Kernel Ability
there were some more steps, but after this my nexus didnt do anything (maybe because of the missing root or the not unlocked bootloader or whatever?!)
it just was stuck in the mode with the android laying on the floor and giving error codes.
so i thought i softbricked it and googled some tutorials to restore a stock rom.
i foundthis and it seemed to work, but it was a bit outdated
i didnt get a .zip from the developers.google.com page, just a .tar, so i couldnt do
Code:
fastboot -w update image-nakasi-jro03d.zip
i just shut down the device then and thought it could maybe already work, because i updated/replaced the bootloader or something like this with
Code:
fastboot flash bootloader bootloader-grouper-3.34.img
but after rebooting it just shows me a completly black screen with a white "Google" in the middle and an open lock on the bottom.
it isnt responding to anything im doing, like pressing on/volume-buttons or connecting usb
the computer cant dedect it via adb with
Code:
fastboot devices
....
what can i do now? do i have to wait, until the battery is dead? this can take days...
i know i did something really stupid
is there any way to restore my nexus 7?
please excuse my bad english and please help me
thank you very much
Hold Power and both volume buttons until it goes off, then power it on while holding both volume buttons. When you see the android, Open Fast boot or a Nexus 7 tool and flash a stock image. You can get them from the Google Dev site. Hope this helps.

thanks for your help.
when i press power and both volume buttons the screen goes black after a few seconds, but it immediately reboots
Keep holding to volume buttons the entire time. It should go into the boot loader.

ok, thank you, it did. im too impatient :laugh:
i connected it and it was dedected, thank your very much
i went to developers[dot]google[dot]com/android/nexus/images, is this the right google dev site?
i already downloaded this file and i only got a .tar when extracting it, but it seems like i need a .img
You could try and use the nexus toolkit. I haven't tried it, but it should be able to download and flash a stock img to your device from the bootloader.
Good Luck

Hey guys,
I know there is already a thread out there (which I also posted in), so excuse me for my impatience, but I really want to fix my N4...
So I unlocked my Nexus 4 bootloader, tried to root it, thought I did but then SuperSU failed and failed and failed and I couldnt get it to work. I didnt make a Nandroid backup (silly me). I got sick of it and tried to unroot/lock my N4 again, using the "How to Unroot Nexus 4 to Stock 4.2 Jelly Bean on Windows!" youtube guide. In that guide, I fail on 8:45-ish where he sees the dead android and then accesses the recovery menu by pressing the 3 buttons. My N4 just reboots or shuts down. So here is the deal:
- I unlocked my bootloader and rooted my device, only it wasnt rooted when I was finished and after a lot of trying to root it, I wanted to flash stock android on it (4.2.2 according to the guide).
- Everything went well untill I had to factory wipe/reset my N4 (youtube guide at around 8:45). When I press power + volume up + volume down or power + volume down or power + volume up my N4 just either shuts down or reboots. When I try to boot normally I am stuck at the nexus X loading screen.
- Now, I cant boot my nexus, I cant wipe my nexus, I cant access it from the PC using ADB and I HAVE NO IDEA WHAT I CAN DO.
I signed up specifically for this issue and I feel like such a douche, because it was running smooth with 4.3 and I just wanted to try out more of Tasker...
Please guys!
The correct button combo is volume up and power. Your phone is most likely rebooting or shutting down because you're holding the buttons too long. Press power and then volume up briefly and quickly let go. The menu will appear.

I got ninja'd by El Daddy and can't figure out how to delete my post.
That seems to be a very specific button combo indeed, I tried it so many times before and I failed miserably. Thank you so much.
I should make a back up more often! I have been stressing over this for two days...
Hello everybody,
I hope somebody can help me to save my N7 (2012).
I installed TWRP without problems and after that I tried to flash a custom rom - which, for some reasons, didn't work.
After reboot my Nexus is stuck at Google logo with an opened lock at bottom...
I can't get to fastboot because when I power on while pushing VOL - button it just get stuck at the same logo screen.
If I keep power button pressed for about 10s, it shuts down but after a few seconds it boots again just to get stuck again at the logo screen...
The only way to shut it down completely is to keep VOL+ button pressed while pressing the power button.
My Windows 7 computer won't recognize the N7 at all anymore, but when I shut it down completely (Power & VOL+), windows says "Unknown device".
Is my Nexus still to be saved or I can throw it away?
Thank you in advance for each advice.

Hi, Conrad-007...
This is very strange - your Nexus 7 is clearly 'bootable' (sort of), with a functioning bootloader, ie., it's not hardbricked... or you wouldn't be seeing the Google logo.
In the distant past, back when I used to experiment with custom kernels on my Nexus 7, it sometimes required the POWER BUTTON+VOL DOWN buttons be pressed and held down for a good 30 seconds or more, to generate the necessary 'interrupt', and force the device into the bootloader.
My first instinct, is to suggest you may possibly have a problem with your VOL DOWN button, and maybe it's stuck somehow or not making contact.
It also occurred to me, that you might be able to access the bootloader with...
Code:
adb reboot bootloader
...or possibly...
Code:
adb reboot fastboot
...and even...
Code:
adb reboot recovery
But unfortunately, I'm pretty sure you need to be running fully booted Android or booted into a custom recovery (eg., TWRP) before you can issue ADB commands. I haven't tinkered around in this area of Android for a couple of years now, so my memory of the specifics is a little hazy.
Anyhow, here's a fairly comprehensive listing of Nexus 7 button presses/interrupts, which maybe of some use...

--------------------------------
Anyway, just some thoughts that might give you some clues/ideas, that may resolve your problem.
Good luck, and I hope you find something that works.
Rgrds,
Ged.
Thanks Ged for the detailed answer.
Unfortunately it seems that my Nexus is not booting complete (not finishing the booting sequence due to corrupted bootloader?) and so I cannot send to it any adb or fastboot command...
I read in the meantime that holding the VOL up button while powering up the Nexus, it will bring it in the APX mode (whatever this mean) and indeed, my computer recognize it as "APX" device.
I hope at least that this is a good sign and a first step to bring my Nexus back to life... but I have no idea what is the APX mode and what can I do in this mode to attempt to save my device...
Do you (or somebody else) have (has) an advice or tutorial for me concerning this?
Regards,
Conrad
Hi Conrad.
I'm in exactly the same situation (I've mistakenly posted a duplicate thread here https://forum.xda-developers.com/nexus-7/general/bricked-tilapia-t4005149). Let's continue here. So:
1. I spent 4 hours trying all possible button press combinations, including VERY long presses. I didn't notice any APX device or Uknown device connected to Windows. I might have missed it, you gave me hope. I will check again.
2. APX mode enables low level access to the chipset via nVidia tool nvflash. You probably came accross these threads here on xda:

https://forum.xda-developers.com/showthread.php?t=2340237
I haven't so far, as I was not aware of the visibilty of the tablet in Windows. I will check again.
Well, I must have been blind not to have seen all the posts here on xda and everywhere else. I went through the threads and now I know:
1. I can see the tablet in APX mode in Windows. Possibly I could correctly set up the driver.
2. This would be totally useless, since I hadn't backed up necessary blob.
