logic board question, any ideas?
A customer brought in an iphone 7 plus that was thrown against a wall. it had a bad lcd but could still see that the phone wouldnt boot past apple logo. now that i have the screen replaced it still stuck at apple logo and im trying to figure it out. customer has data backed up on icloud so 1st thing i tried was to restore/update in itunes. unfortunately i got error 9 every time. also if the phones off and i plug in the charger it will draw .8 amp until i unplug the charger and plug it back in. then no amp draw. im thinking tristar is the problem but not sure because there in physical damage on the heatshield of the board, where it got some small dents from the screws that clip into the frame of the screen. but its not near tristar. ill add some pics of the damage i can see.
Is this a good question?
