I replaced a cracked Iphone 6 screen with an aftermarket only to get that Touch ID failed. I’ve done all the resets, restores, etc to no avail. At one point I was able to get to the fingerprint screen but when I put my finger on the button, nothing would register on the screen. My question is, is there any way to know if it’s the home button flex cable that’s the culprit or the extension cable behind the plate other than trying a new extension cable? It only says Touch ID failed upon initial iPhone setup, I don’t get the message on the home screen that Touch ID cant be activated. Is this indicative of anything or am I just wishing? Thanks for all your help!
Did the replacement screen come with the home button extension cable metal plate pre-assembled? If yes try the old home button metal plate, if that does not work then do a backup of your phone via iTunes then restore (restore will wipe user data). See if that restores touch ID.
Hello I think the problem is in the extension of the home button. Flex home If the button was damaged, the message you said would come out. This piece does not need to be physically damaged to stop working partially. Sometimes it is the action of home and other touch ID. It is easy and economical to try it. Another option is to mount your broken screen and take it to Apple saying no one touched it. Good luck!
I have had a screen come with a bad flex cable extension - but that is for iphone 6s and up. The iphone 6 has the separate panel on the light box that you generally transfer to the new screen. Is the old screen still operational at all? If so, put it back on with your home button and try it out. If your HB works, then its the replacement screen/Extension cable panel bit. Unfortunately, damaging the HB flex cable is a very common mistake made when swapping screens and can generally be avoided using some heat, alcohol, and non-sharp tools when working with it. If you have a microscope or magnifine glass, check out the flex cable too and see if you see any hard kinks, holes, tears or anything that makes it not look brand spankin new. If your not sure, upload some pictures for us to see and we will give you our 2 cents. Good luck!
It is the Home Button that contains a chip that is tide to atleast one of the chips on the motherbaord. When replacing the screens on iPhones always try to take the home button off the broken screen and place it on the new screen. If you don’t you will lose the Touch ID. The only other way not to lose it is to get your screen replacement done at an Apple Store. They will replace it with a new home button, and have the computer programs and equipment to program the home button and preserve the Touch ID on the phone. Richard EValueSmartphones
