Bill, thanks for your information.

I thought the t4 I got was defective. Unfortunately, the set I got only has t4 and above… so now I have to order another one.

Thanks for confirming it is T4.  The T4 I got is from Kaisi 16-Piece Precision Screwdriver Set of amazon (labeled T4x40mm). It does not seem to fit at all.

Is there any trick in using it? I am afraid if I press it very hard, I may stripe the screw.

I did try reset to factory default, no go. Thanks.
