iPhone 12 infinite bootloop until earspeaker module is unplugged

I bought an iPhone 12 yesterday for $80 that was bootlooping or stuck in recovery mode. I Tried all the normal steps at least 50 times. Then I started to take it apart and look inside and disconnect the battery. I was pretty desperate at this point so just for the heck of it I plugged it to my computer with no screen and a meter so I could somewhat tell what was going on. I was able to get it in dfu mode with no screen and it updated on iTunes. Then it wouldn’t reboot so I tried a new screen and nothing. then I just unplugged the ear speaker flex and it updated and restored and was stuck on white screen saying attempting to recover data for a while but then I put it back in recovery mode and module still unplugged and restored it and it’s working fine. I guess my question is is it possible to fix Face ID or to read the old module and write it to a new one so I can turn the brightness up, faceid work, hear? lol
