Maybe it’s because I got my phone when it first came out, but mine definitely had T3 screws. Make sure your screwdriver bits are good quality, I stripped a cheap bit aster 5 screws. Also, I did rip the thing for the wireless charging that wraps around the batters when pulling the back cover off. Make sure whatever you are sticking in there to peel the back cover off is between the cover and the plastic back, and not between the plastic back and the battery.
