What about jjlwork's suggestion of dialing *22803 option 1?
Did you relock your phone before trying the Telus ROM?
Check this (Assuming you used Hard SPL):

I would try jjlwork's options first then, attempt to get your phone back to stock, or keep your phone unlocked and try to flash a custom ROM for Telus.
