iPhone 6 Stuck on Apple Logo with Progress Bar Not Moving After Update
Would much appreciate if somebody could help me please. The phone returned to myself from a customer, it worked fine previously but now it has stuck on Apple logo with progress bar screen after an update to iOS 10.2.1. It turns on, the progress bar goes to the end until 1mm of it stays unfilled and freezes. iTunes recognizes the phone, showing all the phone's details as usual (memory size, serial number, backups, etc). I left it for a few hours, but it still showing the same.
If I do a restore it restores, then freezes again at the end at the same stage, when iTunes already shows the screen with set up as a new iPhone or restore from backup options. I tried hard reset and restore in DFU mode, but still nothing.
If this is related to hardware and if someone had faced a similar problem please share, maybe I should try to reheat some components with a hot air station?
Is this a good question?
