[Mi 3 Q&A, Help & Troubleshooting] astoris:
Please help me with my bricked mi3w 64Gb.

It's not answering on any buttons combinations Vol+, Vol-, Power. When i connect it to PC with disconnected battery it's recognized in 9008 mode and can be flashed with MiFlash.

Here is the beginning of MiFlash log:

After

[000017C0]COM20	3.06	Reboot to mini kernel

it is recognized in 9006 mode and device eMMC card is detected in device manager

The flash process continues and ends in about 120 seconds.

Than I disconnect phone, connect battery, press power button and phone does not switch on.

I've tried to flash with testpoints short. Not shure I did it right - can't see clear under plate covering SIM-card slot. But in this case when i connected it to PC, red light blinked once on phone. The rest of flashing process was the same.

Can someone help me with my problem and give any advice how to revive phone?
