key combination to reboot old firmware version????

key combination to reboot old firmware version???

I’ve heard about a key combination to reboot old firmware? any help/ideas/suggestions???

thanks.

has been a long time since i had my vci100, but i think it is the upper small black button in the left upper corner. hold it while switching the unit on..

i tried that but it doesn’t seem to do anything, I really just want the unit to restore back to its original mapping that is compatible with traktor le but i cant figure out how to make it happen
