Hi folks,

I have been using Acer A510 for almost 1 year now, and upgraded 7 months ago to the latest JB OTA. I haven't ever rooted it.

Since 2 days, it can't boot suddenly, stuck with the following error message:


Booting failed
Bootloader vJB-d0ca683: Starting Fastboot USB download protocol

After a bit of Googling, I tried to unlock the bootloader, as a way to recover the tablet. But that keeps failing as well:


[ [email protected]: /tmp ]# fastboot oem unlock

At this step, I can see the unlock icon and played with Vol+ and Vol- to quickly select the "Unlock" option, and this is what I get on the tablet:


Bootloader vJB-d0ca683: Starting Fastboot USB download protocol

And on the computer (kind of error messages that are of no help):


FAILED (remote: (Unknown error code))

So it appears the bootloader can not be unlocked, and I can not even enter the recovery.

I've read somewhere that it may be possible to recover in APX mode.
So is there any way to recover it (either through the bootloader or through APX mode)?

Thanks for your help!
