Brothers, mine is a Eng device.
I tried to enter recovery . But the screen go blank.
even I go thru fastboot mode. or (Vol up + power)
I tried to directly flash RUU rom. it shown the rom version 1.XX so it should be a rom inside.once the screen show going to bootloader, the device come to blank screen again. and never go thru.
I have try original battery , and a 3rd party battery. It come with the same result.
with / without Micro SD card , Sim card. come out the same result.
I think I will try to flash the "zip" rom m-deejay by using SDK command.
see what is next....
