Hi guys i want to know how to update my ps3 from 3.41 (with a jailbreak dongle) to 3.55 OFW safely and once there at OFW, format my hard disk and restore my ps3 to factory settings.
i would like to know a safe way to do this and ensure no bricks or bans of my ps3 as after i have gone to 3.55 OFW i would like to update to the latest 4.31 firmware to play with my friends online and yes i am aware of the fact that updating past 3.55 means there will be no dongle or cfw compatibility.
Some background information about my ps3 is
when i insert my jailbreak and do the old power eject trick my ps3 boots successfully and allows me to use hombrew although oddly it does spoof my ps3 to 3.55 when my ps3 is in fact not 3.55 but, 3.41 when i boot without the dongle.
also multiman works correctly and backups i have made all function with the correct eboot fixes, multiman does work without the dongle but an error comes up when i start it and i cant launch any games because the correct files to make the game backups work are not present without the dongle but movies music etc work within multiman. the reason i mentioned this is because i am not sure if multiman should even boot without the dongle hence makes me think that some alterations have been done to the firmware when it was jailbroken which then makes me ask will it brick when updating.
I have various other homebrew such as blackbox, open manager, backup manager, psn duplex cracked games and various game fixes eg: batman arkham city by zombie killa
i also have two corrupted files in my ps3s installed data files came from gt5 and mortal kombat i case that matters so basically what i am is asking is how to make my ps3 like it was when it came from the factory (completely stock not even a slight trace of modding,if possible) so i can ply with my friends
also since i used a dongle am i still on ofw, if any more info is needed just tell me and i'll post it
any help will be greatly appreciated
