Jason, first try to do a complete reset of the phone from the settings along with the USB storage (Remove your SD card from the phone though). then if it won't work try the link i posted above, it shoud return you completely to stock 2.3.5 GB
Edit:
i've never updated through Kies, Everytime I'd plug my phone to Pc and activate Kies it would say "you device is not supported upgrading via Kies" I'm just guessing here but the Kies update might have messed up your phone even more, what you also may try is search for a DarkSide superwipe on xda site flash it through CWM touch and that should completely clean your phone, and then try the UCLF5 again or the GB 2.3.5 stock via Odin.
here is the link for Darkside Superwipe http://forum.xda-developers.com/showthread.php?t=1477955
I've used it a few times and it works great.
