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.
