I haven't used a service tool as I can't get into service mode.
Tried from off, press hold power, press resume 4, 5, 6 times no service mode entry.
Others on same firmware I have talked to have same issue. Prior to firmware 2 seem to work fine.
My question was not on the software tool, it was how to get the Pro-100s into service mode as the posted methods do not work on firmware 2.031.
I read the thread you reference, and the issue of service mode for the Pro-100s was brought up there but not answered.
