A few hints:

* heating up the phone works great. I used a heating pad that you put in the microwave to heat sports injuries.

* also, I made a sheet to help you keep track of the screws as you remove them. Print out the page, then place double sided tape below each color-coded listing of screws, and stick the screws to the tape as you disassemble. This helps prevent losing the screws and keeps track of what screws are what for easier reassembly. https://drive.google.com/file/d/1pLSvKvB...
