(adsbygoogle = window.adsbygoogle || []).push({}); EDIT: If it's not working for you, then I'm sorry. This worked for me, and I'm online on my 3.55. I thought I would post WHAT I DID to get back online to try to help others.
SEN/PSN Enabler: You must login or register to view this content.
Download PSID patch: You must login or register to view this content..
Install .pkg on ps3.
Start PSID patch.
Click "X" about 5-6 times(spoofs PSID).
Click "[]" about 5-6 times(spoofs Console ID).
Click "^"(Triangle) to exit the homebrew.
Reboot PS3.
Sign in.
That is exactly what I did to sign back in on my banned 3.55 KMEAW PS3.
P.S. I would highly recommend using a dummy account while online, and not your main accounts'.
