I also used a metal tool to disconnect my battery on an iPhone 6s. I got a small spark. The phone after that would not power up. I fulled reassembled the phone and then plugged it into a wall charger. After a few seconds, I got the battery picture on the phone and then it powered back up. No issues now, working fine. So if you have this same issue, try this first before taking it in for repair.
