Is it a patched v20 rom that you flashed? Flash again using SmartFlash and once the phone boots, it will take you to the CWM recovery screen and then do a factory reset and wipe Dalvik cache. Then reboot your phone and it will be just fine. BTW read the "Noob how to" section in the Q&A it helped me a lot.
