You probably did this, but did you confirm the lock by going in to the bootloader and comparing it with the screen shot on the locking/unlocking/flashing post?

If so, try the directions for flashing from your internal storage. I never had problems flashing from my computer but then I started having connection issues so I tried doing it from my internal storage and I will never go back. It is awesome. You can keep a stock version of the rom on you storage and reflash it on the go if you have to bring it back to telus. Definately the way to go. Good luck.
