Hello everyone,
I found a nexus 7 on a second hand website for 20 euro's.
In the tekst he sayd that the nexus dos'nt boot up after upgrading the firmware update.
So i thought its possible to try to fix it.
If i start the nexus 7 i get the google screen with in the right top the tekst start.
if i push the power button the nexus restarts and shows the same screen again.
I can swith between start, reboot bootloader, recovery mode ecs. but all dos'nt work if i push the power button.
When i try to start the bootloader that works fine but when i try to unlock it, i get the screen with the security warning and i can select yes to unlock it or no.
But when i again push the power button it reboots and nothing happens, the nexus is'nt unlock.
Is there a another way to do this or is it ready to trow in the garbige?
Is there maybe a acript that automticly push yes in the unlock bootloader screen?
Sorry for my bad english.
Best regards.

Cf Autoroot automatically unlocks the bootloader if it is locked: http://download.chainfire.eu/295/CF-Root/CF-Auto-Root/CF-Auto-Root-grouper-nakasi-nexus7.zip
worth the try. Try to flash the latest factory image after that
I tryed that one, but if i run it i get the unlock bootloader screen where i must select yes or no to unlock, but there i get stuck because if i push the power button to enter he reboots and i get that screen again.
Is there no solution to enter "Yes" in de unlock bootloader screen without using the power button or is there a script / program that auto write / flash the nexus 7, because i can't still flash that damn thing.
Asus must use another program to bring back the ship that is in the nexus, is there no thread or something that handles that problem without sending it to repair it.

Hey all, requesting some assistance...
I had used the nexus 7 toolkit to unlock the bootloader and root my tablet.
Earlier this afternoon, I decided to cave and flash cm10 on my tablet. Before doing so, instructions stated to wipe. In my ignorance, I wiped one too many things and also wiped the internal memory.
As a result, I am unable to get my tablet to fastboot and when I searched for the .zip to flash, I was presented with an ominously empty file directory to my sdcard's root. I have tried various things with the nexus 7 toolkit and have been unsuccessful in my endeavors, as many of those functions require the tablet to be in fastboot mode before any of them will work.
The device is stuck on the Google screen, and if I push the volume buttons with the power button, it will flicker and eventually return to this screen.
I do have a nandroid backup stored on my machine, but I am unable to use it as I am unable to even boot to the recovery (because I can't get to fastboot)... Any suggestions? I really hope I didn't brick this...
I believe you can get to fastboot mode with the v4.13 bootloader from any other mode so long as the battery is not dead and the screen is working.
When the battery has a good charge, hold the power button down until the google logo appears (could be up to 15-18 seconds). At that very moment that the black-and-white google logo image appears, press the Vol-down button.
Voila. Fastboot.
You do need to see that screen appear though; maybe that's the rub. Note that the timing is important - you only get one second or two to do this immediately after the image first appears.
As a bonus, glance at the bottom of that image. Shows an unlocked padlock for an unlocked bootloader, nothing if locked.
It worked! Thanks a bunch!

No worries. Glad it worked. Actually, I only stumbled across a reference to that button sequence a couple days ago.
If you see someone else reporting that they "can't get to fastboot", let them know - you can get there from ANY MODE.

Don't be this guy...
My nexus 7 2013 was found frozen with Google in white on screen. research led me to Nexus Recovery Toolkit. Tried to unlock bootloader and all ok until tablet asks yes or no. I use vol button to select yes and power button to confirm and nothing else happens. I've waited for a few hours but it just sits on that screen until I intervene and reboot into bootloader screen again. This is also the only screen I can get into.
any help appreciated.
Our nexus 7 has decided to stop booting. It will charge fine but if we try and switch it on it will get as far as the rotating circles and stops there, displaying the rotating circles till the battery runs out. I have done a factory reset but that had no effect either. I have looked at reflashing the OS but all the ways of doing it require developer mode to be enabled and the tablet will not boot to let us do that. Can it be activated any other way? I can`t remember if it has been updated to lollipop as my wife uses it, not me, but i think it has. Any help would be appreciated.
Hi! You don't need USB debugging enabled to flash stock. You use fastboot to flash firmware from the bootloader screen. ?
(the adb reboot command is for booting into bootloader from inside the Android System... Which you can't do anyway)
Follow this guide,
http://forum.xda-developers.com/showthread.php?t=1907796
?
To get to bootloader,
Power off the device completely.
To enter Fastboot Mode you will need to press and hold Volume Down and Power, all at the same time.– do not release the buttons.
Release all buttons when the Fastboot screen appears.
– that’s it, if you see the START option listed in the upper part of your screen you’re in.
Select Fastboot.

Hi i my htc u11 ultra dual sim is stock, it is rebooting or get stuck what can i do to recover phone
when i turn it on it doesnt pass the screen saying HTC powered by android then restart, if i press volume down and power it gets to a screen but if i choose reboot to bootloader reboots to same screen, if i choose boot to recovery or to download modes it reboots but gets to HTC screen and then reboots.

I being trying to use fastboot but computer doesnt read phone.
Please help is urgent to recover my phone
Can you try boot to download mode (Press volume down when turn on your phone)
It reboots on htc powered by android screen, never pass that screen. and i only enter to bootloader menu direct when pressing volume key and power, i dont have a menu before, and there is i press the download mode or recovery mode phone restarts gets to HTC screen and reboots.
I try using the adb commands but i connect the phone to my laptop, it is shown in devices as android device my htc, but the adb devices never recognize it. So i cant to anything there. I was thinking of using XTC2Clip(no sure if that helps and how it works), but i cant affort to buy that and not work. So any recomendations on what else i can do i will appreciate.

I don't met that problem before. Maybe your device have hardware problem, i'm not sure. I can not help you. Sorry.
Thanks anyways
Same problem here. It keeps getting in the boot loop forver
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...
https://forum.xda-developers.com/showthread.php?p=37606945#post37606945

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:

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.
I have a new paperweight
