I have a broken flex cable on my iPhone 6 home button. It’s completely cut in half. Is there any way to repair? I didn’t do this. LOL Im a repair guy. This is shoddy work a customer wants me to try and fix. Error 53 is solved BTW right? Honestly haven’t had issue with error 53 before, so I suppose it sounds like a stupid question.
Realistically, no it is not possible. You are unfortunate that the tear is so close to the actual button. In theory, you could re-establish the connections that were severed . In reality, there are 6-8 connections on a flexible mylar strip only a few millimeters wide and you have very little flex to work with. This would be a super challenging task for a very experienced micro-solderer. This is clearly not a DIY repair.
I hear that Apple can in fact repair these. If you can send them the device they have tools that can (supposedly) recover keys from a dead button but its not cheap. There are actually ways to DIY this but still working on it. I had some success using an X-ray device of my own design on memory chips with similar geometry but this is extremely dangerous and only works with an original button. Effectively the code inside is stored on a PROM which lacks an erase window so X-rays of the right intensity can wipe it making the ‘phone’ recognize it as a new button in Apple’s Horizon Machine but to actually re-code the button again needs a lot of effort. Swapping button with a phone containing a matching serial range is possible and others have reported success with this method earlier but YMMV. Generally speaking the closer you can get the serial the better chance it has to work.
