TL;DR My aunt asked me to update her iPhone 5 that was on 6.0.2 to the latest 7.1 Manual update with IPSW file - error message: 'Firmware is incompatible' Manual restore with IPSW file - error message: 'Firmware is incompatible' Official (slower) update/restore through iTunes - error message: corrupt download during update. Tried updating on phone directly - error message: corrupt download during update. ----------- To make the update faster, I downloaded the correct IPSW file and manually went to update the iPhone after creating an iCloud backup. It gave me the error message 'Firmware is incompatible'. This was strange because I made sure I downloaded the latest and correct IPSW file (iPhone 5 GSM 7.1 - she's in Europe, so it's GSM). I tried manually restoring with the same IPSW file and it didn't work. Then I decided to go the official (but slower) route and I got a different error message "corrupt download during update." I tried updating on the phone directly and got the same "corrupt download during update.' message. I'm out of options for the update - what do I do? Her phone is on stock iOS 6, not jailbroken or anything. I've never seen the latter error messages so I don't know how to go about it. Added problem: iCloud didn't save her Camera Roll during the backup. Any recommendations?
