A lawfirm in Seattle is considering a class action lawsuit against Apple, in regards to "Error 53" message showing for some iPhone owners which have had unofficial "dodgy" repairs to their iPhone's Touch ID sensor.

Sources say, 'PCVA' which is the firm investigating the option and also soliciting complaints from people affected by this glitch. The message is usually triggered when people get unauthorized repairs which tampers with the Touch ID sensor and then try to update or restore their iPhone. The phone is then unusable and avoids warranty.
PCVA claimed, noting that the public would find it unacceptable if car makers forced drivers to bring vehicles into an official dealership for service. PCVA has made a few comments.
"We believe Apple may be intentionally forcing users to use their repair services, which cost much more than most third-party repair shops,"
In its defense, Apple has said that it's trying to protect the security of users. Touch ID normally saves data in a component known as the Secure Enclave, and in theory unofficial parts could be used to steal a user's fingerprint. During official repairs Apple re-validates the pairing between the Touch ID sensor and the Enclave.
If you're impacted by Error 53 to contact Apple Support, but to date the only known solution has been to get a replacement iPhone.
