As I posted when I bought my S3, it was rooted and had an unlocked the bootloader. I also had clockworkmod installed, backup my rom before trying to install CM10...
Little did I know...
Remember a few weeks back, when it came out that there was a undocumented code that, from the dial pad, could factory wipe the S3. Well Samsung Pushed an OTA update to patch that exploit. And little known to me, I got it, and it locked my bootloader. FAIL!
So I still had root, Just not a unlocked bootloader, So after Much research on the subject, I am following these set of instructions. http://forum.xda-developers.com/showthread.php?p=28530409#post28530409
I am downloading the Rom now so I can Flash it back to stock, then fix the bootloader, then to CM10.
When I am waiting for it to download, I am going to play the Campain mode on Black Ops 2.
More to come...
