[Q] Nothing will work to unlock mt HTC 7

view story

http://forum.xda-developers.com – I have Been trying to get my HTC Mozart Rom fully unlocked or even interop unlocked however i just get errors every time i attempt to run Rom update utility. I run Windows 7, have mobile device centre and activesync as well as zune e.c.t.. I usually get the 294 error at 3% meaning it is the incorrect RUU, when i do find the correct one it never gets past 0%. Interop unlock also does not work. I attempted to download and load it under connection set up e.c.t.. and it does not work. stays fully locked, although i am developer unlocked thats not enough for what i want. Any sort of help (HowTos)
