PS3 Slim 3.70 Downgrade and
PS3 3.7x Downgrade for Slims and Fats with NOR Flash news, this weekend Italian PlayStation 3 hackers
DiGiTaLAnGeL (linked above) have made available a guide to fast swap PS3 Slim CFW 3.55 to OFW 3.70 with 2 HDDs and
ProgSkeet followed by a
New Method - PS3 Downgrade v2 Supports all NOR Flash from
TwoStone.
To quote, roughly translated: Today I'll write a tutorial to "fast-swap" between CFW 3.55 and OFW 3.70, using 2 HDDs... at the end of the tutorial, you'll be able to swap between the firmware just flashing a dump on your PS3 using Progskeet. (instead of downgrading and losing all data).
The first steps are not so easy, so take your time and go on, by the way, you must have some skill with Progskeet, and it must be 100% working...
