This is totally my fault that this happened, because I didn’t read both guides thoroughly before starting, but there needs to be a big red “STOP” symbol at the top of this guide that says “Stop! If you intend to replace your screen, start there first. Do not replace the battery and replace the rear cover prior to replacing the screen.” I am out 2 hours of my life and have to wait for another back adhesive piece. But the bright side is the battery works great and combined with a fresh factory reset the phone is running like new.
