(adsbygoogle = window.adsbygoogle || []).push({}); I have the b777x eboot on but my account was working fine yesterday , but I signed in today & when I click play online , it does it unlimited times without doing anything... ): I just created this account too , anyone help ? I've been stuck like this for days & im not getting a lot of info from people ...

Click play online about 10 seconds after you see the store appear.

Sign in through the XMB. You need to do it every time in order for it to work.

Load up BO2 while offline.
Sign into PSN via XMB
Wait 10 seconds and then play online.

Also, if the problem persists and you just can't play; your acc is banned from the server. It seems that you don't get a ban message anymore on cfw ( personal experience recently ).

i made new acc and used new unbanned cid still not working

You need to sign in through the XMB or you will get the infinite loop.

mine says server unavalible and i did that aswell

Delete the updates and reinstall them.

Can I back it up?

It won't erase anything... Why would you want to back it up?
