Did you by any chance bootstrap? Might want to sbf, but instead of wiping data, only wipe cache. If you haven't, reboot to recovery (hold x and power recovery), and then wipe cache. Then reboot and let the update run.
On your stock 2.4.330, root and install CWM.
Head to CWM, perform a backup.
Once done, SBF, and update to 4.5.607.
On 4.5.607, root and install CWM.
Head to CWM, choose Advanced Restore and restore only the /data partition.
