Error -1 iPhone 7 plus
a customer brought in a iphone 7 plus for a screen repair, but it had a broken lcd so i was unable to test it before i opened it. (note ive fixed about 30 7/7plus without issues.) anyway after installing the new screen I found the phone lagging and freezing up. but it wasnt my screen because the power button was also lagging and when i opened voice memos the record icon was unable to be pressed, also i only use oem apple lcd replacement parts, refurbished by myself so i know they arent fake. anyway I tried to restore the phone to see if that would fix it because i know there have been alot of issues with ios11 and im getting error -1 and now the phone is stuck in recovery mode...if tried updating/and restoring in dfu still not working. another note i tried both itunes and 3utools. when i flash on 3u i can see that it fails at 80% when trying to flash fuddata.
