Purchased the iPad air 2 on launch day back in October 2014. Never had any issues with the devices was a very solid tablet worked great no complaints. Last night 11/4 decided to upgrade to iOS 9 FROM the latest iOS 8 version. Upon trying to update via iTunes I immediately received an error code 53. The iPad was stuck on recovery mode only option was to restore (bummer because I did not backup) but not a problem went ahead and restored and couldn't get the iPad to restore because I was still getting the same error code 53 tried this same process on 3 different MacBooks. Final result was error code 53. Did numerous research online and mostly people wrote that if any parts were changed the screen/touch ID button this issue will occur but NOTE my iPad has never been repaired or has been damaged/water damage etc. Note: Warranty expired October 24, 2015. Called up Apple Support they were clueless first rep had no clue what an error 53 was. As they put me on hold for maybe 10-15minutes they told me that only thing we can do is replace the tablet for you as its an hardware issue. Although, the hardware was working fine since purchase, I updated from previous iOS 8 versions never had any issues. So I'm assuming iOS 9 bricked my iPAD OR this a mystery for me. Any feedbacks or if anyone experienced this as well feedbacks would be appreciated and also this thread is great for anyone else that may encounter this situation. Sorry for any grammatical errors.
