I tried this procedure to increase system partition
After formatting, I clicked on download & plugged in the device. It remained stuck at 100% downloading with red for sometime and then opened a window with some error suggesting pressing some key combination and to look at error log.
I am stuck, please help...
BTW my phone had ..._MMX_16_flasher_user as build number. I believe it is stock ROM v2 and this method (and this ROM) is meant for on my phone.
