HELP: ONDA V712 don't turn on (died) after an upgrade

[Aprevitali]

Hello

I tried to upgrade an ONDA v712 but apparently this didn't work and the device looks as dead.
I tried to press any key combination and the device never turn on and it is not recognized by the PC.

I don't know how to enter in the recovery mode in this scenario and I think a reflash is the solution.


Anyone knows how to rewrite the flash with the onda tablet v712 turned off at all?


Thanks in advance
Andres
