You cant go into bootloader?
Shutdown the phone, upon start up, press the power button + camera key together and the bootloader screen should start?
When screen black outs or manualy locked with power button , and then try to unclock device just restart and turn on, i think i mest up with image files
where i can get all image files?
What to do?
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.
I tried to unlock the bootloader on my OPT, after I had already unlocked and locked it. The phone does not start when i hold the power key, it does not start recovery when I press and hold the volume down and power key. It starts in fastboot mode when I hold the volume up and power, but when I type a command in cmd is says that the device is not unlocked and the command failed.
When type "fastboot reboot" it shows the oneplus logo and the "powered by android" and after a second, black screen, nothing.
I will appreciate it if you could help me....

It's not adviced to relock the bootloader once you already unlocked it.It can cause strange issues.

Hello,
my OPT won't dispaly anything.
When you press the pwr button the display ignites for a short time in dark grey and the blue buttons glow.
Then nothing comes to the screen, no andoird boot logo etc. Just a black screen.
You can connect it to PC it will identified correctly as a A0001.
Fastboot commands in fastboot mode is possible but you see nohting on the screen. recovery mode is just similar wehn you hiut the button combination it vibrates the display ignite for a short time drak gray then nothing appers.
When in fastboot mode and test OEM unlock the device's bootloader ist locked.
All combination with pwr button hit and Vol +/- no response , nothing shows at the screen is stays black
The Display is changed by a new one so a Dispayy error is not possible.
Mega unbrick guide passed through have the Oxygen image on it but after pressing pwr button nothing appears on the screen
Any Help for me possible. ?
