Apple has apologized to iPhone customers whose phones were disabled after third-party repairs, and issued a fix for the problem.
Some customers found that their iPhone stopped working following servicing by a non-Apple technician and saw an “error 53” message in iTunes.
Now, Apple has released a software update to fix the error.
In a statement, Apple said that “error 53” occurs when a device fails a standard security test designed to ensure that the Touch ID fingerprint scanner is working correctly.
However, the company added: “We apologize for any inconvenience, this was designed to be a factory test and was not intended to affect customers.
“Customers who paid for an out-of-warranty replacement of their device based on this issue should contact AppleCare about a reimbursement.”
A software update has now been released so that iPhone customers with disabled phones may restore their device via iTunes on a PC or Mac.
Apple had even faced a class action lawsuit led by a Seattle-based company over error 53-disabled phones.
