Updating your ps3
So if you really really do need to play online, you cannot have the jailbreak too.However, playing splitscreen games or local LAN multiplayer does not need PSN access and will still work on jailbroken PS3s. Sony Hates Jailbreak Unlike Apple, Sony is way more anti jailbreak.First you need to verify that the TV has the ability to have PS3 connected by examining the back of the TV for RCA plug inputs.The PS3 comes with a A/V cable with 3 RCA color coded plugs on the back and you plug those in to the back of your TV.While you’re safe to keep a jailbroken PS3 offline, it might get banned from PSN permanently if sony detects it.
To back it up, go into settings and find the place where you back it up. No, but there are system updates which apparently crash your PS3.A wired connection works best with the PS3 so that it doesn't have to maintain a wireless signal. Check the red light is on, on the front of the machine. The back of the PS3 has a spot for an Ethernet cable to allow wired connection with the internet.Try using your connection without the router or computer and then… Decide on your input method (Audio/Visual cable, or HDMI) Plug the appropriate ends into the TV/PS3 Ensure the power switch on the back of the PS3 is off. Purchase a Cat 5 or Cat 6 ethernet cable long enough to go for the back of the PS3 to the source of your internet connection.If you like more pros than cons go ahead and jailbreak your PS3 system.I have two PS3 systems so I can have best of both worlds.
