1. work for sony and form a crew like Sly Cooper
2. Devise a plan to secretly gain access to thier central security unit which contains the bans.
3. Bypass security checkpoints.
4. 'Silence' any obstructions by all means.
5. Have your bently character hack into the main processing unit to find the password.
6. After hacking into the system find a file named 'bandilist' right click and delete.
7. Escape as the alarm is at high alert, there will be a window. Fly out 007 style, you should have your own theme song.
8. Meet up with team via PS3Scene, confirm that all bans have been released.
9. Prepare high five with team.
11. Profit, Sony will be shitting themselves in fear. We will then have control over sony.
But seriously, create a new account and a new PS3 profile and delete the banned profile. Then run the program, it should work as this only unbann the PS3 itself, not the account you use for PSN
Are you trying to use the same account that was banned? There is only one way to unban an account.
