Default [Q] Acer A701 Only APX

Hello/

Charged tablet , unexpected reboot, no led, no vibro, no screen, nothing. Full Brick with APX.
By clicked on reset button + power, windows are accepted tabled as APX( no led, no vibro, no screen).
I am try to install a few drivers, but adb, fastboot can't see device, nvflash see as "UnKnown device found".
I don't have CPUID, SBK and have no root, stock firmware 4.1, and locked bootloader.

What can i do ?
