As stated here and in my testing the best way to keep from scratching our heads with what look like bugs that no one else seems to have or only a few of us have is to ALWAYS flash to stock rom, HARD reset and then Flash to custom rom and HARD reset.
Do this every time you try a new custom rom.
I have set hours trying to figure out WTF is up when a simple reflash and hard reset fixed it.
Make sure to hard reset after stock rom and after custom rom.
It appears that some files get left behind during the flash process and it can cause hours of headaches.
Most common errors I have come across by not doing this are clock, keyboard and dialer problems.
Save yourself the headaches friends.
Take the time to do it right the first time.
