Help with restoring backup

Hey guys I'm new to Android in general so sorry if these seem like dumb questions. I've searched online for a while now and I can't really seem to get a concrete answer. Anyways so I got CWM 5.5.0.4 running on my 7510 just fine last night. I then did a backup of everything from within CWM 5.5.0.4. Then I went and flashed CM10 Jellybean to see if it worked fine. Went back to CWM and tried restoring back to ICS, to check that too and it worked fine. I want to mention at this point I couldn't get Titanium Backup or ROM Manager working from withint ICS at this point because it kept saying that it couldn't get root access (I rooted my 7510 through the method listed as a guide in the Developers section of this forum), but since I could restore back without a problem to ICS with all my settings intact, I thought I'd give it a try anyways.

I then flashed back to CM10, and upgraded to the newest CWM Touch version 5.8.x.x from within ROM Manager once in CM10. I then decided I wanted to go back to ICS so I tried to restore back to ICS through CWM Touch, and it didn't work. I’ve tried doing an entire normal backup, and then strictly the apps, nothing works. Keeps telling me there’s an error.

What’s the best thing to do? Switch back to 5.5.0.4? Can I do that without turning on USB debug mode? Because I didn’t check this beforehand but I can’t click on Storage in settings and even access USB period, whether it’s to transfer stuff or to turn on USB Debug mode.

Any help would be appreciated! I mainly want to go back because all my apps are setup the way I like in ICS. Unless someone knows away to restore apps properly back without going through CWM, maybe through some app that can read the backup data if that makes any sense?
