26w ago - Following up on my guide, the way I see it Sony will soon patch my console unban method, in my opinion it will be possible to work around the patch, I however won't release it publicly but below I give you PS_Unban v0.1 for 3.55 and v0.1.2 for 4.21 Firmware.
PS Unban is a tool to unban your PS3 on both 4.21 and 3.55 firmwares (different pkg's) (the 4.21 should work on both but meh), no console ID needed.
If it gets fixed i'll patch it a few times.
Install either "PS_Unban v0.1(4.21).pkg" (UP0001-NOBAN0000_00-0000000000000000.pkg) OR "PS_Unban v0.1(3.55).pkg" on your PS3.
Update: PS_Unban v0.1.2 is now released HERE and is out of BETA so grab that version instead.

Let me get something clear, there is no 4.31 CFW, that's a 4.30 CFW spoofed to 4.31. So both Rogero and SGK CFW are actually 4.30. If by 4.31 you meant exclusively SGK, I believe that's under development and shouldn't be used at all due to instability and giving quite a few people bricks, so It would be recomended If you change CFW. I don't mean to be disrespectful towards the team but that's just the way It is.
