1. I got a problem, I deleted my old PSN account to login wid the new 1 but every time i try to connect it says the servers are down. (BTW i was using PSN enabler too to play SFCO). Then i tried to login with Gen B but it says "System Upgrade needed". My question is : Should i use Gen-D2 to access PSN from VSH menu?

2. Secondly, I need to downgrade from D3 to D2. Is pandora battery necessary to downgrade CFW?

Any help will be greatly appreciated
