my iPhone 7 home button not working , one of third party technician was tried to replace u10 chip but unfortunately while removing damaged my upper flex ( attached steel round button) and also he was failed to re install u10 , now my iPhone home button not having chip and also touch id not working just i wanted to know the confirmation that if replace the u10 my touch id will work again or not ? please let me know EDIT:
Update (10/26/2018)
this marked upper flex damaged it can be repair with jumpers please let me know i want atleast Touch ID instead of home button
I suspect that the flex was damaged, which is why the Touch ID is not working. If this is the case, then a U10 IC will not make a difference. Normally, a damaged U10 does not impede the function of TouchID. Can you post some pictures so we can see the damage?
