HELP! iPhone 7 could not be restored
My Iphone 7 got stuck in a boot loop about 3 weeks ago. There was an attempt to update to IOS 13.1.3 overnight and the update failed. The Iphone was never dropped or had water damage. After that my Iphone was stuck on the Apple logo screen. I have tried restoring using iTunes multiple times in DFU mode. The restore process will get to “Verifying restore with Apple” and stuck there forever (longest I waited was 5 hours). The iPhone will show the Apple Logo and a progress bar at this point, but the progress bar never budge. After killing it and checking the restore log from iTunes, the last line I saw before getting error 9 (for disconnecting) was always “operation 29 progress -1”. See screenshot below for excerpt from iTunes update log.
I have also tried flashing using 3uTools and the process is stuck at 20% - Unmounting filesystems step. Is this an indication of a hardware issue? If so, is it the Logic Board?
I brought my phone into Apple Store and they didn’t bother fixing it. They told me I should take it elsewhere to see if someone is willing to fix. I need to get it to turn on at least, to be able to trade it in.
Any help/expertise is greatly appreciate.
