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.
let me explain as i know i'm not the only poster with this problem, i just haven't seen a solution posted. till now.
it has taken me weeks to find the answer.
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.
now i can manually install the qc driver.
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.
