- Download and install the official firmware 3.55: http://www.filefactory.com/file/c3f2a75/n/Firmware_officiel_3.55_Retail.rar
- Prepare a USB stick formatted in FAT32 and create a folder called PS3, then in that same folder, create another one called "UPDATE" in which to copy the file (PUPs should be renamed PS3UPDAT.PUP).
- Connect the USB to the console and turn it on.
- Install 3.55 OFW through the XMB
- Once the firmware is istallatoo, download and unzip CFW 4.21 Arch
- Replace the PS3 folder on your USB stick into one file provided by the CFW Arch 4.21: http://www.filefactory.com/file/5jq9mdw4njqd (CFW Arch CEX 4.21 Finale version v0.1 PS3FAT / CFW Arch CEX 4.21 Finale version v0.1 PS3SLIM)

Update: They have now released (via ps3-solution-pour-tous.doomby.com/blog/news-ps3/cfw-arch-4-21-finale-version-0-1-for-all-ps3.html) PS3 CFW Arch CEX 4.21 Final v0.1 for both PS3 Fat and Slim consoles (above) for those interested!
What FW would you recommend? If you have any links, they would be much appreciated. I could probably even update my CFW guide if I had a better understanding.
As for the procedure, it is covered fairly extensively in the Rebug and Rogero threads... if you need links I can dig them up.
And if I do, what's the procedure? Same crap or did something change?
Thanks in advance to anyone who answers it.
To quote, roughly translated: Revision 2.00 CFW Update to 4.30 released with CEX ARCH fixes and additions detailed below and a version of MultiMAN v04.13.00 Stealth.
As a reminder, a version of MultiMAN Stealth allows you to play backups of your games when connecting to PSN but you will appear as extended spirited play on the game demo version of JAP-NPJA90067 instead that you see on MultiMAN. A big thanks to Deank manager for Great About!
