Many thousands of iPhone users are up in arms after the latest software update has left their iPhone’s inoperable showing the Error 53 message, but this doesn’t affect everyone.
The issue arises if you have had your iPhone repaired by a non-Apple service centre. You could have had your phone repaired at any point in the past. For example, if you dropped your iPhone and replaced the smashed screen and Touch ID sensor, it has probably worked fine since the repair but as soon as you install the latest iOS9 software update, it will render your phone inoperable and display the Error 53 message.
The software update basically checks your phones internals to see if they all match up and if they don’t, the phone becomes inoperable. Apple told The Guardian that this is a security feature that has been introduced to remove the risk of a compromised Touch ID sensor being installed and used for fraudulent activity.
This is all well and good, but the thing that has iPhone users annoyed is that there has been no warning that this could happen before the update is installed. It is understandable why people use other parties for their phone repairs, as they can be a fraction of the cost but Apple stand firm on this and note that any iPhone repairs should be completed by Apple. It is also worth noting that if you don’t, this will void the warranty and you could end up paying £270 to have your disabled iPhone replaced by Apple.
