I take it your Rooted.... Just take your SD card out, link it with your pc, put the Rom you were using before on it or a new Rom, put back in ya phone & access the recovery menu via the bootloader screen (if you don't know how Google it), now once in clockwork mod recovery just wipe the partitions, then into advanced & wipe the dev cache, then flash your Rom! Reboot then should be fine again. If this doesn't work follow the steps again & do a full wipe after the dev cache wipe & then you will be ok. If this still doesn't work.... Google the rooted stock Rom for your phone, download that & follow the steps again.
Hope this helps :)
