Touch ID fails to setup after disassembling iPhones with iOS 10.0.2

Touch ID fails to setup after disassembling iPhones with iOS 10.0.2

Hello, I was disassembling several iPhones (my included and an iPhone of a friend) both are iPhones 6 with 128GB. I replaced twice the display of the iPhone 6 of my friend, and everytime it worked properly. Same was done with my iPhone. Then today I had to open both iPhones. And after assembling them again, the Apple TouchID sensor (which are original and not swapped) were not functioning anymore. Both iPhones tell me "Failed Unable to Complete Touch ID Setup", I already did all the tricks. Reset, Hard-Reset, iTunes downgrade to iOS 9.3.5 (from both 10.0.2).

Could you have forgotten to reconnect the Touch ID ribbon cable while putting the phone back together after the replacement?

"I replaced the home button flex ribbon cable. All is well after restoring the phone. TouchID works.

I felt the home button flex cable connector ""snap"" into place solidly. That was reassuring.

The next reassuring event as not seeing the immediate ""TouchID cannot be activated on this iPhone"" message immediately after powering the phone on."

Did you purchase the screen replacement kit from IFixIt? If you did you might have purchase the option thag doesn't come with the conductive plate. Without that platells Touch ID will not work.

"Frank: Two things.... NO there is no Problem with touch IDs and IOs softwares.... and yes there is a flex damage..

try this...

1.open both phones, remove both lcd. (disconnect battery)

2.now u have two lcd and will work only in one phone (the other one put to the side with out screen)

3.now time to troubleshoot. in the one phone you decided to work on. plug in the others phone lcd.

(plug in everything... lcd, dig, long home flex, proximity

4. plug in battery, and turn it on... (see if it worked)(your done)

5. if did not worked on the same screen that is connected (swap only home button and do step 4.)

6. if it dint work still, on that lcd long home button flex is damaged.. now use the second lcd.

7.second lcd has no home button bc u removed it, connect any of the two home button and do step 3 and 4.

8. if didn't work, with that same second lcd do step 5.

9.. do same thing with the other phone u put aside on step 2.

-----------

expert explanation:

test out both home botton flex (long one) and both home botton with each phone.

if doesn't work both long home button flex are damaged. (wort case home button is damage)

add: go to setting --- touch id---see if gives u error."

"What model iPhone is this? If it is an iPhone 6, Then I would bet dollars to donuts they damaged the backplate flex cable that connects the home button to the motherboard. This cable is very sensitive in most cases your home button will still function but the touch ID will stop working if this cable has been damaged at all.

Replacing the back plate with touch ID flex cable will 99% of the time correct this problem."
