Before I begin to explain the situation, let me state that I have not had a screen replacement, and got this phone in December. ‘Okay, so basically, I was taking a test yesterday, and fully powered off my phone. When I turned it back on, a message saying “unable to activate Touch ID on this iPhone” came up, and the home button is unclimbable. I have looked in the settings, and resetting my fingerprints is not a option as they are no longer there. I did not drop my phone that day or anything to possibly damage it.
Since your iPhone was bought in december and it has less than one year just go to nearest Apple Store / Apple Authorized Service Provider and repair it for free since is still under warranty (in Europe the minimum warranty is 1 year from Apple, don’t know about the warranties in other places). If you don’t have one near you you can send it to them here is a form
I would first suggest a hard boot. If you can, try holding down the home button and power button at the same time until your phone powers down. Keep holding until you see the apple logo, at which point you can release. If this doesn’t work because your home button doesnt work, we will find some other way.
Repair the button if someone can connect the wire to home button again.
