In case you had a problem with the fingerprint sensor or some other small defect on your iPhone 6 and had it repaired by a non-official (read: cheaper) shop, you may be in for a nasty surprise: error 53. What happens is that during an OS update or re-install the software checks the internal hardware and if it detects a non-Apple component, it will display an error 53 and brick your phone. Any photos or other data held on the handset is lost – and irretrievable.
