Repair firm iFixit, in an unusual move, sides with Apple in saying that the reason for the issue are to ensure that only genuine components are being used so as to prevent malicious hardware modifications. "Once a third party changes the home button or internal cable, the iPhone checks to be sure that all original components are running the phone, and if there are any discrepancies users face the "error 53" message and can't access their data," iFixit's Kyle Wiens told the newspaper.
