What is (unknown error 56) iPhone 6

I am getting unknown error 56 on an iPhone 6. I have used three different computers. I changed out the screen on this phone but I did retain the same home button. The phone was working perfectly fine up until trying to upgrade to 10.2. Thanks for any help.

According to the iPhone Wiki:

''Error 56

Most likely a dead/glitched Touch ID sensor. If seen on iPad's, try restoring the latest firmware in DFU mode. If error still occurs, bring your device to Apple. On iPhones, take out the SIM card and try restoring in DFU mode. If still occurring, bring your device to apple.''

That is wrong, NFC fault is error 53.


@pccheese it's still an answer even so we may think it is wrong. Not a good choice for a REMOVE AS NOT AN ANSWER vote. ;-)
