We are unable to carry out this modification to

Slim 3K and 4K models - This is due to the fact that the consoles left the factory on a higher firmware than V3.55, so this means we are unable to downgrade your console to a firmware lower than what it left the factory on.

Can you take a CFW PS3 on the Playstation Network?

Due to the fact that the console is no longer a standard console, it makes it unfair for other players on the Playstation Network. This is due to the fact that you can modify games to give you more money, infinite lives, etc.

Sony states that this breaks its Fair play ploicy, so you have a risk of your console being banned from the network. There are some utilities you can install onto the console to hide the fact that your console is modified (these are listed below).

Our recommendations are

Create a new user without PSN and set it as default user. It will prevent accidental auto-login that could cause a ban from PSN.
Never login to PSN with syscalls enabled (Alwaysuse SENEnabler, PSNpatch or webM AN MODto disable the syscalls before play online.
Do not cheat if you go online and enjoy CFW!
