So I ordered a display on eBay for the Huawei P9 (EVA-L09) and started to disassemble it. First I unplugged the battery connector and then all the other ones, removed the old cracked screen and put in the new one and plugged the connectors in (I contacted all the connectos, the fingerprint scanner too without popping the back body on and the battery connector as the last).....I held the power button and the phone turned on, it vibrated and play boot sounds but the screen didn't turn on and was black + the display connector got hot to touch..... anybody knows how to fix this?
