updating to ios9 after screen replacement lead to error
I replaced the screen of my Iphone 6 after it is damaged. Only the screen was damaged. The TouchID was working fine. It was in the latest version of IOS 8.
After the screen replacement everything worked fine, Except the fingerprint. Whenever I tried to open the fingerprint option in settings, it automatically scrolls to the next page and says something like " unable to .......try again". At that time, Apple released ios 9. I tried to update, but failed. Now the phone is in itunes mode. I tried to update to Ios9 and ios8 so many times. Sometimes it shows error 3194, sometimes error 53. I tried everything I found online. It includes modifying hosts file, and installing ios while the touch ID and screen are unplugged. Even the service centre is unable to do anything. I hope I could get some help from here.
