Touch ID Repair Theory
Hey guys, I have a thought on repairing the touch ID on an iPhone just in general. So, since the touch ID home button and CPU are essentially ‘tied’ together with a unique ID which I’ve heard is encrypted, and obviously button replacement warrants the touch ID as useless due to different ID’s, but, say someone who were to have enough skill in SMD rework on logic boards, could the CPU possibly be replaced and then the new home button could be paired with the new CPU. There’s most likely other chips that will need replacing but I just thought about it and there seems to be absolutely nothing online anywhere about it other than repairing the button flex which could be missing as some 2nd hand iPhones or logic boards don’t come with them.
The reason I ask is that I have a couple dead logic boards at home and I’m a begginer getting into SMD rework and I’m looking at buying iCloud locked boards, replacing the respective chips to remove the lock and since a lot of these don’t come with home buttons or no touch ID, it really devalues the phone. So I thought I’d get some view and opinions on it. (yes it may not be cheap or economic) but I just want to know if it is possible. Thank you
