Vibrates every second, no download no recovery, changed power button
Hello guys, i'm trying to repair my girlfriends t989, you know all girls are destroying phones. so the problem is, that you put in the battery, phone 1st time boots and after 5 secs, just black screen and vibrates. i've searched for this problem, and it says that is the power button, yesterday i changed it, so i thing its something with software, any help guys?
UPDATE: i can go in download mode, but only for a few secs, then slighly blue screen flashes and again vibrating
Is there any way to flash software not through download mode and recovery?
