To everyone, if you download a game then patch it MAKE A BACKUP of the files you are patching first. That way when something like this happens where the patch is no longer needed you just restore the backed up files. EASY. If you didn't back up the files then your SOL and have to download the whole game again for your stupidity. How hard is that?
Here's a quick easy tutorial.
1, download the game, backup the game, however you get the game have it on your PC.
2, make a directory "355 patch" in in the game dir. That way you will know what files are patched and which patch goes to which game.
3, copy the patch files into that dir.
4, copy the game to USB HDD or Internal HDD via FTP.
5, copy patched files into that same dir.
6, play game. You now have a backup of the patch and a backup of the game with the original files. So when you update to 4.30CFW you wont be crying "has someone got the original files?"
If thats too hard to understand then HOW did you get CFW on your PS3 in the first place?
