Do the mods apear on your 3.41 PS3??? Go into LAN and see.
No, just a normal game, I know for a fact I've transferred the patch back over to PS3. I've had experience with WinSCP and Cyberduck so I know how to use FTP and other SSH programs.
It's Mossy's patch that I opened it Hex WS and copied over to my patch and then uploaded that back to the PS3. Turned PS3 off, switched of from back, removed the USB, turned PS3 back on and went back into MW2, went to Lan and no mods.
I guess I'll try again tonight or on weekend or something as my PS3 light keeps flashing red and turns on for about 5 minutes before giving me a message about getting too hot and turning off. I doubt it's getting hot when the fans on nearly full and pushing out hot air at the back before going cool because the fans pushing hot air out so quick.
I never got this "hot" error before, only after I jailbroke it.
