after 2 days of reading now to find either checksum utility... Oh a point of order... after OFW3.55, KMEAW3.55, should the most recent ver. of MM be downloaded, checked, installed (does it have tools necessary i.e. key dumper) ?
Since there is little on my new fat 60gb (a couple of demos, saves, psn acct. installed back in 2009 just to check unit) should I reset to default before starting updates from OFW3.15?
Don't know how I missed this the past 2 days, early onset dementia maybe... or staring at tiny notebook instead of the PS3 crap-o-browser on my 55"LED Sony HDTV.. THEN using notebook for downloads... sucks being senior citizen... lol
