Hi there! I bought a used IP5s some weeks before. I disassembled it and it looks like the home button is a replacement part. There aren’t any capacitor/resitor on the cable, it looks exactly like that one:
The manufacturer label says “SU”. The originals should looks more like this (and should read “HK”), right?
Is this correct, I mean - maybe there are more than just one producer and the cables had a revision? Is my cable an original one (i cannot test touch-id because of some other issues at the moment).
It doesn’t really matter because each home button is paired with the logic board. Once you break it, you can either put an aftermarket replacement or even an original one from another device but it will only work to click, meaning no Touch ID. Seller should have disclosed that.
