The new nightly build seems bugged to me. When I download it it's 9.7mb and i cant open the file without getting errors.
If you can't wait, try this link http://jenkins.cyanogenmod.com/view/All/job/android/8410/artifact/archive/cm-10-20120920-NIG...
just convert from GPE to stock using this ruu. if you already have correct cid and mid, you can flash this zip via fastboot oem rebootRUU.
THL firmware support VoLTE and VoWifi. Give it a try.
