Recent media reports, plus the battery would lose its charge quickly
Your videos encouraged me to attempt this. The 000 screwdriver was a bit too pointed, so I filed the tip. Your videos didnt clearly show how the grounding contact should fit (it did pop out as cautioned in the videos), but I figured it out. Having a magnifying glass available really helped me.
The phone now holds a charge "as new". I am very pleased!
Patience, a positive attitude, maybe a second person as observer/coach...
