Answer to: Home Button Not Working After Battery Replacementagh. i was sweating bullets for a bit with this problem. ultimately, I touched the two gold prongs down by the lightning port, as stated above. i was touching only one, like a dummy, with the screwdriver. then, i got my head straight and realized i'm supposed to touch them simultaneously with the screwdriver. once I did this, the home button activated on the screen. i can't believe my phone is still operating.. the screen had become unglued from the screen assembly, and overall my battery replacement was a messy sweaty nervous affair. thank goodness i stumbled on this fix.. which would be obvious for an electrician, but not for me.
