If you are looking to enjoy the famous game from Valve on Portal 2 CFW3.55, well you should take your troubles patiently, because in the short term it is impossible to play with it on a console CFW 3.55.
Our friends at PS3 Crunch we learn that the first game the keys encrypted with firmware 3.60 arrives, and it is the famous game from Valve => Portal 2.
Based on early returns, despite all the tricks commonly used to run all games on CFW 3.55, it is impossible to cast.
Without the decryption key firmware 3.60 which will allow us to decrypt the eboot. Bin, it is currently impossible to run the game from Valve.
And it appears that future titles such as LA Noire may follow suit.
We hope that our friends hackers manage to find a new solution to start the next game with encrypted keys FW 3.60.
