Hi Guys, I’ve been repairing iPhones since March of 2010. I’ve owned a cell phone buyback company since then as well, so I’m not a beginner in the repair/refurb game. So I went to quickly replace my old 6 plus battery, opened it up, did NOT remove the LCD just let it sit open. (I usually remove but expected a quick replacement). I pulled the adhesive tabs under the battery, one ripped so I ended up having to pry up a bit on the old battery. Other than that, the old battery came out fairly quickly, new one went in, closed the phone back up and the home button and Touch ID both didn’t work anymore? So I figured it happened when the LCD fell briefly and twisted the flex cables (I’ll be removing all LCD for all battery replacement now). So I tried quickly replacing the LCD back plate with a working one from a parts phone. The home button worked but the Touch ID is still not working? It gives a message when the phone is turned on saying Touch ID failed? What’s going on here? This is a first for me, how did the Touch ID get affected at all by a quick battery replacement? If it was the home button flex cable, why doesn’t Touch ID still not work after replacement flex was installed? I never touched the home button area or Touch ID sensor so I’m not sure what happened? This one has me stumped and of course it’s my personal phone, I’ve never seen this on any other battery replacement I’ve ever done. Please help
When prying out the battery, which side did you pry from? Left side or logic board side? Have you made sure you didn’t knock anything off? Try cleaning all connections and reconnecting them to, also look for any cable damage etc. :-)
