Not true at all. Error 53 can be fixed. As long as original home button has no damage, or actually touch ID has no damage. I got iPhone 6 in for a screen replacement and while attempting to power the phone. Guess what screen i got? If you guessed connect to itunes, you win a headache. I was about to tell the customer she was done for. She said phone is out of warranty. Well then then, i told her i will take a look thinking that the home button will be damaged. No damage at all. Just a bit of liquid damage ONLY at the home button connection at top of the board and a filter was not making connection.
I fixed this phone when Apple can't/won't since out of warranty. The myth of error 53 needs to be explained. It is not related to home button, but ONLY Touch ID. The device i fixed did not have home button function(customer did not care leaving for out of town). If touch ID ever fails on your phone, run to Apple store. Yes, that is right, an independent store owner send people to Apple store all the time.
The other people need to stop posting that only Apple can fix certain things. Provide a solution and options for the people that have an issue. Stop being mean. I see more hatred then help.
My goal is to help people. That is my entire life. Seeing the face of the lady that has her phone working and not having to pay $300 for out of warranty. You should see that face. Also the screen replacement was a swap from an original iPhone 6 before any lame attempt to call my shop using bad parts or anything else. I also provide a better warranty on my repair than apple on a new device.
There are BAD repair shops for certain, but lets identify the good ones for those cases that Apple store is not an option for the customer. Even if it will void Apple warranty. We all need to think about the customer first. This is a help forum, so let us all get together and find a best solution for the customers in need. I will for certain try my best and be 100% honest.
