And make sure: NO DISC IN WHEN YOU UPGRADING!!!
One time I had a disc in & I upgraded to 3.72 OFW. So be careful
This is totally out of context but. I upgraded to Rogero and everything went perfectly. I was able to play all my games with the fixes.
Then I installed the 4.40 spoof, and now when I try and play one of my games (Naruto Shippuden Ultimate Ninja Storm 3) It says
"Game data is corrupted, The game will close. You must delete the game data to play this game"
I don't have the game data installed, nor do I have patches. This only started happening once I installed the 4.40 spoof.
