If you look at the "tools required" here you'll see torx screwdriver, needle nose pliers, tweezers, etc. So whoever started putting this together probably intended to show how to replace the batter cells inside the casing. But those steps are missing. If anyone has a guide to how to actually fix bad cells for this specific battery, please share!

This is it. This was the step where I cracked the screen and ruined the device. Things had been going so well up to this point. Like many others I struggled with the iOpener, so I used a heat gun along with a temperature sensor and very carefully and slowly went back and forth along the edges keeping the temperature at exactly 200 degrees F. I got the pick in, went around the top corners, down the sides to the middle. But on this step where you finish sliding the pick to the bottom right corner, I got 3/4ths of the way down and CRACK. The glass shattered pretty badly in the corner, and there’s a crack running diagonally along the entire device. I put clear packing tape on top to keep it from cracking further, but sections of the screen are non-responsive. I can’t tell you how upset my 5 year old is going to be when he wakes up tomorrow and I have to tell him daddy wrecked his iPad. :( I believe strongly in the Right to Repair and this kit is fine. But GO SLOWLY, and BE CAREFUL.
