It's that time again whereby MFW users can enjoy PSN access for a brief while, as some anonymous parties have decided to put out the PSN version 4.21 passphrase in the wild, and "Luckystar Chinese" (kill me for using Google Translate) has posted up a tutorial on how to gain PSN access via FuckPSN, alongside the 4.21-passphrase-patched files/certificates.
Here's the post from the aforementioned forum member over at Duowan Forums

The networking cheating curse you BAN Oh. BAN directly off the account + the host ID + MAC address
How to use:
The 1. The program open permissions, etc. dev_blind (enter after twice choice, have opted for Yes), then run OpenPS3FTP. Replace the PS3 within CA27.cer certificate, replace the original file to / dev_blind / data / cert / suggestions to replace the backup finished to restart PS3.
Computer running FuckPSN. If an error to see if the computer takes 53,80,443 port. (Usually 53, if you have the machine running DNS service related procedures)
3.PS3 network settings will change the PC's IP DNS started if you do not know - run, enter cmd in window type ipconfig / all then view the local IP of the NIC
confirm works on REBUG, replaced the CA provided and restarted my console (well the current CA is cached on memory so I need to restart the PS3 to refresh the CA's.) then after that, just changed the DNS setting and all others remain untouched, and poof, PSN Access!!
Although, I still cant download PSN stuff on my PS3 due to an error (Installation Failed error, just like in PSP)
So, if I understood it, this solution requires replace CA + Spoof + F***psn + DNS settings.
Who had SEN Enabler installed should then revert to 3.55 (without spoof), install spoof 4.21 (not using SEN Enabler), replace CE via FTP (downloaded from this thread), reboot, change DNS settings and connect.
