CDMA Bell programming the tp pro phone?

[Pyroman]

so here is my issue: just got this htc tough pro its got the EnergyROM installed on it

I am with Bell on a contract, and I already went through the bell website to change the phone. So the TP is added to my account, i got the lock code, and according to the bell website it states to punch in ##12345# (12345 being my lock code). after typing that in it should take me to the screen with the MDN menu to add in my phone number.

well typing in that ##lockcode# doesn't start anything.
someone told me that custom ROM's may have a diff way of programming the phone.

Any ideas? new here pls help in layman's terms
