Support Restored to bad contacts file, device stuck on booting...

view story

http://androidforums.com – So I was using Titanium Backup to restore the contacts on my device, and I really wasn't considering that the contacts file data wouldn't work, but it did come from my galaxy s2. So after this it eventually froze, and now it gets stuck on the Samsung logo while booting. I used CWM recovery when I rooted just yesterday. What can I do to fix this without losing my data? It's just the Contacts file that needs to be restored. (General)
