Think he’s talking about the plastic back panel, and I’m guessing he means the tri-wing screws as there is no torx screws on Switch
As I mentioned in the above thread, if you tried all the other methods I mentioned there, then your left with simply drilling the head of the screw off with an M2 drill bit, remove the back panel, then afterwards use some pliers to unscrew the remaining screw stump
Think the cause of this issue is likely as result of the wrong size tri-wing screwdriver being used, plenty of sellers are selling a tri-wing screwdriver (red handle usually) intended for DS which is not a match for switch and/or theyr’e selling screwdrivers which may as well have come out of a christmas cracker with cheese grade steel which can manage taking out a couple of screws before the end starts sheering off afterwhich it shreds all remaining screw heads
I have the following which has two tri-wing style bits included, one which is a perfect match for the Switch tri-wing screws
