Old battery blew up like a balloon, pushing the screen out and bending the circuit board
Repair went smoothly, except for the instructions to remove connector #1. I could not remove it from the left as shown in the guide. I removed it from the right even though the guide strictly recommended against it (and it worked fine). Luckily after putting everything together, the phone came back to life.
Take your time. Have cups handy to hold the screws. No need to use a lot of force. If you think you have to, then something is not lined up correctly.
