Hi, I replaced the housing body frame of Iphone 7 and 7 plus. but after everything was installed on the new housing place and put the screen back, I tested out by turning on the phones. Then both of them stuck on Apple logo. I tried to hard reset but nothing works. Just to make sure if the charging is working but when I plugged it in, it doesn’t sound or vibrate at all. Could someone suggest me what the potential issue here or what I can try…?
test them out of the housing with the logic board, screen, battery and charging dock connector and then do a prompt to boot a iphone good luck
