I'm curious about this as well.
I want to revert to official 3.55 so I can try a different jailbreak method. I used Geo's and I wanted to try one of the others.
i found out how to do it here are the steps
1. get the original firmware from the sony website and put it nto a usb, put that file into a folder called UPDATE and put that folder into another folder called PS3
2. remove all power from your ps3, with the slim remove the cord and with the fat use the switch
3. insert the usb
4. give your ps3 power again
5. start you ps3 into safe mode to do this
hold the power button on your ps3 until you hear 3 beeps and it turns back off. then hold the power button again until you hear two beeps right after each other. get your controller connected to the ps3 with your charging wire, and select update system (not sure what its actually called
but you get the idea) you will now go back to OFW and you still get to keep all your pkg's since they are now signed
if you have ?s feel free to ask :bro:
