cannot sim unlock my htc one for the life of me, any help?

ok, so i went about to sim unlock it. unlocked bootloader, rooted, tried solutions 1 and 2 here: http://forum.xda-developers.com/show....php?t=2586704 without success. i cannot s-off my phone to do all that fancy stuff, but i have tried flashing different roms. NOTHING seems to be working. i also tried using an ruu tool, but every time i relock my bootloader, i can never get it to boot. it always boots back to fastboot. heres what the fastboot says, too lazt to take a picture:
M7_WLS PVT SHIP S-ON RH
HBOOT-1.57.0000
RADIO-1.00.20.0315
OpenDSP-v32.120.274.0909
OS-
eMMC-boot 2048MB
[today's date and time]

thank you, as any help is appreciated, and i am getting frustrated lol :)
