I'm working on a friend's soft bricked W8. (I'd gotten it soft bricked bout 2 weeks back but that's a different story) I've been flashing a stock rom through flash tools, rooting and flashing cm 7.2 just to restart it and find it soft-bricked all over again.
This latest time, i flashed the stock rom n rooted it. i wanted to flash this ice cream bread rom i found in the forums which said i needed an 'nAa-13' kernel for it to work. but on flashing it through flashtools and restarting the phone, it showed an nAa logo and then shut down. i think the phone is hard bricked cos it doesnt even light up any led on connecting it to the PC.
