Well I just dropped in to say thank you to GregoryRasputin.
I had a fat ps3 3.55 before but then go ylod..Reballing it didn't not pan as I ripped pads when lifting the rsx chip..
Anway finally got the E3 after awhile of waiting and waiting for progskeet 1.2, come back here to load up ultimate fool proof guide downgrading tut and I'm forced to view this page..Which I might add was awesome to be forced to view as I was just going to load up a rebug firmware.
I've successfully downgraded 4.25 to 3.55 and am now running Rogero CEX-4.30 v1.00 / multiMAN ver 04.08.01 / Showtime 04.01.208..I realize alot get worried about bricks but if you read, almost and if not everything is on this site and you should have no problems if you just read enough and follow directions
Looking forward to my second downgrade tomorrow
Thanks again GregoryRasputin and to others that made it possible..Also to ps3hax.net for all the useful info I've obtained in as little as 8 hours to perform this install
