Why? the motor is TURNING ..

Indeed, the topic starter should try to clean the SDM contacts first.

Why? the motor is TURNING (Hence the Contacts are fine) those contacts are a simple DC connection, originally there to power the Cheezy power zoom actions on some FA lenses and they either work or don't work..

the issue is that the cam just that the camera can't lock focus and probably more a Glitch in the firmware data download which has unfortunately left the file with the same checksum - or dud data on Pentax's site, or copy from card glitch ..

I'd suggest the OP downloads again - copies to a card freshly formatted in the camera and re-loads
