Reply to How to roll back the SE's firmware?

I know I've seen it a couple of times on here b4, but i can't remember exactly what it was, and i can't seem to find it now. It was, like, restart the vci and hold down the jog wheel or something.. anyway, someone know?
-and, is it the same thing to roll forward again to ean's firmware?

I just got my pretty, new SE(!), and i got a shiny copy of traktor LE. So, i unwittingly uninstalled my traktor 3.3 demo for a "full" version. Now, I can't use my vci at all, unless i use the regular vestax firmware.

I believe i'm gonna just wait til wednesday and use my free LE to upgrade to
3.3


OR, do i need LE installed to get the 80 dollar discount on the upgrade? Can i just use the 3.3 demo until im ready to buy and use the LE serial to get the upgrade?
