[Q] only 1 ROM topic

I hit the wrong button the other day while trying to reflash stock to my S3 and wiped the system folder. the brain had farted and forgotten about the lock out. only had a older version of TWRP so was only able to install Cyanogen 10.0.0.0 and now I can't flash anything else. not a newer version. not a different ROM. everything else fails. I think the error message said something about a boot loader.

it works but CM 10.0.0.0 just isn't working for me (I HAVE to have a camera for work).

any recommendations or suggestions would be greatly appreciated.
