Root [AT&T] I think I flashed without nand backup

[kosmic]

I hope I didn't mess something up, but I used Titanium Backup to backup all my apps. Then I installed Ultimatum ROM on my AT&T GS3. It seems to be working fine. But I did not make a nandroid before installing the ROM.

If I ever want to go back to a completely stock phone, am I screwed? I thought the Titanium Backup was enough but apparently I need a nand backup?

I'm finding procedures online to restore my phone. I'm going to go ahead and do that since there are a couple of features of Ultimatum that I don't like.

Good homework!
As you know you're not screwed, as long as you can enter download mode you can flash back to stock no problem.

Make a backup of your efs, if you haven't already. And put it on your computer.
