There is several possibilities to this: A/ He's damaged the main board in his process of repair B/ Proximity or Dock flex issue (whether it be its not plugged in properly or damaged) C/ Some how he's managed to corrupt the iOS D/ TouchID flex/sensor The issue of the home button could be because he's put the metal plate behind the home button back the other way round and therefor not pushing on the bit that sticks up on the plate. My suggestion would be to go back to the repairer and get him/her to fix it, or seek some sort of compensation. **Just went back to re-read your post again a couple times, did he put a new home button in your phone? I've seen cases where new TouchID home buttons don't work together with the main board, and will go on an endless loop of restart and blue screen.
