Also in relation to the release of official firmware 4.55, KW has updated his popular PSNPatch homebrew. This version includes a more complete 4.55 version spoof, the importation of new certs, and an updated version of webMAN. For those that want to stay connected to the PSN with their modified firmware, this is one of the best ways to do it. However, it is said that at this time you may encounter issues when launching with Habib firmware that's spoofed to 4.55. Check out the complete rundown below!

Update:

if you are spoofing your cobra 4.46 to 4.55, please update to psnpatch 2.22:

CURRENT VERSION [2.22] Feb/06/2014

• Corrects small bug importing cert when spoofing version. if you spoofed 4.46 cobra version with psnpatch 2.21, please use psnpatch 2.22 to remove spoof, REBOOT and activate again.
• Spoofs cobra 4.46 firmware to version 4.55 (*);
• Imports new certs from files/cert/ when spoofing version.
• "cobra_version.txt" is now on files/ (older cobra_version.txt will be deleted at startup);
