Since a few months my Huawei Ascend Mate has been bricked, so i bought the Mate 7 and never looked at it again. Now i'd like to use it as a mediaplayer, but i can't get it to work. All of a sudden a few months ago it started doing random reboots a few times a week, then a few times a day and eventually never booted again .. the screen is just lit up in the black light without logo or anything .. What could be the problem?
