If I leave the boot jumper on 2 and 3 it will not flash the z code as stated in the manual. The generic file does not appear to be on the stick just the updated and it isn't doing the trick. We contacted verticle Express and they referred us to the local thyssen office and they have been less than helpful getting the generic file. 3 duplexes on the job and I've checked and tried all 6 sticks and files. Still no love.
