Hey this is the steps I took to get this rom working.
1. I mounted my sdcard, and erased everything off of it.
2. I did a wipe data/factory reset in recovery mode.
3. I wiped the ext partition
4. I wiped dalvik-cache
5. I repaired ext partition
6. I then wiped the data partition again
7. I then flashed the new rom
8. I then rebooted
If you follow that, I pretty much promise it will work.
Do not bother with any of this unless you have the correct radio, and spl!!
