For two decades, the worst error you could see in technology was Windows' "Blue screen of death." It's a sign that something is seriously wrong with your hardware or software, and you might be looking at hours or days of frustrating troubleshooting or repair.
However, the blue screen of death might finally lose its place in infamy to Apple's new "error 53." If you see this error on your iPhone, it means that your phone is completely locked. Your information is probably gone and Apple can't do anything to help. So, how does it happen?
This problem started popping up for iPhone 6 users who had had their phones repaired by third parties, or even had phones with mild damage that still worked fine. Specifically, it happened when phones started updating to iOS 9.
Once error 53 appears, the phone is completely locked. Affected users who take the locked phone to the Apple store are being told that the only fix is to buy a new iPhone. Even the data on the locked phone can't be recovered.
