Apple issued an updated version of iOS 9.2.1 today that brings with it a fix for the iPhone-bricking Error 53.
The fix will only work for users who updated their iPhone via iTunes, so over-the-air updaters are out of luck.
Error 53, you may remember/have experienced, is caused by third-party retailer repairs on iPhone Touch ID buttons and subsequent attempts by users to update their iPhone. First detailed by The Guardian, the error was also reported to occur when users had a cracked iPhone screen replaced at a non-Apple Store location.
If you’ve encountered Error 53, here’s what you’ll need to do. First, make sure you have the latest version of iTunes on your Mac or PC. Then, with your iPhone connected to your computer, force restart your phone and try restoring it again. The fix should bring your phone back to life, but be advised it won’t restore its Touch ID function.
If Error 53 still isn’t going away, Apple suggests you contact Apple Support.
Apple apologized for any inconvenience caused by the error in a statement sent to TechCrunch.
“…this was designed to be a factory test and was not intended to affect customers,” the statement read.
