Looking for help - my son's iPhone 6S was lost or stolen. I have a backup 5C that I've activated until his 6S can be retrieved. I want to restore the 5C to a previous backup in my iTunes, but it will automatically install iOS 10.3.3 and I've read that the iOS is bricking 5C phones. Anybody have experience with a 5C and 10.3.3? The current iOS on the 5C is 8.4. Any advice?
