It seems u have applied too many patches to your backup. I had the same problem. Backup your game again or restore the original PSARC and Eboot files and then apply the "Uncharted3FixRepackv5.zip" patch only as mentioned by
. You don't need to extract the psarc files. It also fixes the freeze in Chapter 11 on Drake's Journal. Also check your file size. The Pak22/23.psarc should be around 8.14GB or u have a bad rip. Works on rebug cfw 3.55.2, I have the same.
