Hey,

I need some help here.. As i said I killed my 9a with 9c rom and the phone doesnt start at all..
It vibrates after power button is pressed, but screen goes black...
I already tried to reflash it with 9a roms (2 versions of miui)..then factory reset using android toolbox but problem remains the same.
I also flashed engineering rom - no success.
I suspect it has a problem with preloader .. But nothing seems to be helping..

Is there anything I could try before removing emmc..to repartition the memory and flash fresh stock rom?

Thanks a lot

Ehm..thanks for your response Harsh gsm.

I want to ask..what is the difference between write partitions using ufi toolbox and mrt tool?

I cant afford to buy new box just because of this phone :(

I searched a little and found this option :
"Write factory Flash file format"

Im I right?

Hello pradeep_kus... I tried sp flash tool at the very begining with no success...i think it has something to do with preloader and boot1 and boot2 area... must try to parse the preloader with the correct emmc I figured out..

Or am I wrong?
