CHUWI HI10 PRO is dead

[zlatko]

Hello!
After a year, my HI10 pro is dead again. After charging during night, Chuwi is dead. There is no led light, I can not turn on, when I connect charger, there is no led light,……
I was try flash the BIOS with external usb programmer and done.
But, after I can not start tablet using +/- and power button to install android, tablet will not start in DNX FASTBOOT MODE???
I was flash Bios again, but problem is the same. I was also check battery, 3,77V.

Any another solution to start tablet in DNX FASTBOOT MODE or is tablet completly dead

 

I was try my last idea, disconect battery red wire from motherboard and connect tablet on the charger, but no result. Tablet is completly dead, battery has 3,77V, on charger 3,80V. But I can not boot tablet in fastboot mote to install android.
Tablet working normal until I was start to charge battery. When I connect charger, LED diode is on, next morning, there is no LED and tablet is dead.

May be motherboard demaged?
Have anyone idea?

Regards
