Need some help with t490/t490s

Just wondering what's the best method for removing bios passwords on them we get 100s off them but since you can't do the driver bypass. Need most consistent method.

Try to program back your backup file and see if the device works or not.

I think the patched method will not work with your device, maybe you need to use a proper programmer to program the SIO chip.
