1. Don't manually update the game from multiman(#YouCant)
2. Upload your BLES BO3 Games, Internal, Not External(Which I havent tested, but could be an issue)
3. Download the update packages from pc, and install it on ps3 from the package manager.
4. Load the game from either Multiman or WebMan (Don't Lauch it)
Once you did that, Lauch the game from APP_HOME.
If you still get errors, try using the BLES fix.
But, tbh. I installed bo3 with no problems like any other normal game would.
