Q2: How can I update my CFW or OFW? A2: First you will need the updater file either from Sony's website if you want OFW or from any CFW team's site if you want CFW (for CFW I suggest using Rebug), then make sure the file is named to 'PS3UPDAT.PUP' (w/o quotes), so make two folder labeled 'PS3' and 'UPDATE' respectively (MUST be caps and w/o quotes).
