I did manage to get to S/W upgrading once (but didnt have the other steps installed/finished yet.) I think i did it by eventually doing step 5 (after all the step 1 stuff) on lelus fastboot.

Im hoping i cant just jump right off there (IF i can get it to get to s/w again) as im guessing all s/w upgrade screens are the same point.

Crossing my fingers that i can figure out how to make all this work! Stupide security lock
I get an error cannot load ' '
