From ComputerWorld: Apple today re-issued iOS 9.2.1 to fix the "Error 53" that had crippled iPhones whose owners had replaced some parts themselves or had a third-party shop do repairs.
The new iOS 9.2.1 will only be served to users who update their iPhones through iTunes on a Mac or Windows PC. Most iPhone owners retrieve updates over the air using their cellular connection, and so will not receive the replacement.
Error 53 appeared on iPhone 6, 6S, 6 Plus and 6S Plus devices after a do-it-yourself or third-party repair job replaced the Home button -- which includes the Touch ID fingerprint-scanning authentication sensor -- the connecting cable, and sometimes the screen. Once the error appeared, the iPhone was "bricked," or rendered unusable.
Reports of Error 53 sparked indignation among some iPhone owners and was criticized by Kyle Wiens, the founder of iFixit.com, who saw it as a threat to do-it-yourself repairs. "Owners have the right to repair their products and get them repaired by technicians they trust," Wiens said in an email to Computerworld last week.
