Does anyone know if there are command line switches to allow the Windows Software Update Wizard to set the 770 into R&D mode? Can a frontend be made for flasher.dll that allows you to easily set the bit on the 700 for R&D mode?

I snooped through the DLL, but i did not see any functions that might allow this...
