My phone stopped working during one game. It don't start anymore. Some time it shows 1sec red light (when connecting to PC without battery) or 5sec red light (if connected to PC and pressed down vol + power). It seems like dead any way. I didn't find a solution in other threads. I tied to flash it with MiFlash, but without going to fastboot it seems not possible. There is is my try: Win7, digital signature disabled. The phone recognized my system. Seems ok. MiFlash 2012.11.06.0 or 20140509 don't matter on second try As the phone cannot start to fastboot mode, I think MiFlash simply don't find a device. I tried some tricks with ADB, but it don't find a device also. What is the problem in general: battery, partition, firmware, hardware ? What can be other steps ?
