first, THANK YOU dragonhart6505 for your youtube vid how to install motorola qc diag driver for unlocking motorola droid razr m/hd (xt907/xt926). your words "hit vol up so phone boots properly" was what i was missing.
my problem was i wasnt really in diag mode.
heres how i resolved my problem. i went back to stock rom (4.1.1). im not sure, but i think i had to do this. i think nv mode is disabled by custom roms. that didnt resolve my problem completely though. i found out i wasnt really in diag mode (bp tools for my moto). i thought i was booting into bp tools mode. i did the three finger salute. i scrolled to bp tools. let phone boot and plugged it into usb port. no qc port (not even one that needed a driver). couldnt create a virtual serial/com port either using hw vsp. got a lan error. cdma workshop stated no answer from my phone. i could ping the ip though with no errors. all because i wasnt in bp tools mode as i thought! UGHHHHH!!!! after scrolling to bp tools, hit vol up (no dont scroll to factory reset). youll see when you do it.
then i was able to manually install the qc driver. then i could read in cdma workshop.
the other thing i learned along the way was that with windows 7/8 (yes, and 8.1) the qc diag driver must be manually installed.
