Touch ID not working after battery replacement

"@ Ben.

You can't put home button cable in and then connect battery cable on a 5S, it's almost impossible."

"Hey Micheal,

Having the same problem after battery replacement.. :/

Did you fix touch ID problem? If yes, please advise."

"After installing my battery replacement from iFixit, I had TouchID issues too. Couldn't be initialized or something. I would get the message repeatedly on the home screen, but couldn't set up TouchID in Settings. I even disassembled the phone again and followed the accepted answer on this thread regarding the proper order for reconnecting the screen and battery. It didn't help. I thought perhaps doing things in the wrong order prior had damaged something and TouchID was just never going to work on this phone again.

While troubleshooting a reboot issue with the same phone, I came across an article that suggested doing a settings reset. I tried that and it fixed the issue for me.

Go to Settings > General > Reset > Reset All Settings.

I hope that helps!"

"I tried everything in this thread including the reset all settings above. What finally did the trick is a hard reset (ie, Erase All Content and Settings). I did do an iCloud backup before and restore after and that did not affect the touch id, it still worked after the hard reset.

The previous suggestions in this thread will likely fix your problem, but in case they don’t, here’s one more thing to try. I unplugged/replugged the battery and home connectors so many times and it just wasn’t working for me. :)"

The iPhone 5s line has a really annoying home button cable. In my opinion, one of the hardest phones to get the home button cable re-connected. As a tech that works on phones all the time, I can tell you that getting the cable seated back on correctly can be difficult. It’s possible for the home button to still register that you’re pressing it but have Touch ID not work. This happens when the ribbon cable is not seated correctly. If you are still having problems, I would try re-seating the cable on the connector. Try to get a good click. It’s hard to get your fingers under the screen and re-attach the cable so I often use a pair of tweezers. It also worth noting that in the process of working on the phone, you may have damaged the cable meaning that Touch ID will not function even if you replace the home button. Every home button is liked to the phone any only Apple can link a new home button to a phone.
