I do not recommend to try it without a flasher installed and a dump of the flash.
To quote, roughly translated: Hi all, What better than to come back with this kind of news! Our friend and SGK developer releases today the result of hard work. Indeed, in the shadow he worked to bring us a CFW with features interesting and not yet seen the new CFW 4.xx
The basis of this CFW is based on Rogero 4.30 and the 4.21 Rebug CFW which is the most stable and most successful of the moment. He added SGKXMBM + Package Manager for our greatest pleasure. Some files from firmware 4.31 which ensures compatibility for the latest keysets. So you can play your backups favorites without a patch or fix. 4.31 is a spoof includes access to PSN and avoid unintended updates.

Thanks for all the Help, I have fixed my PS3 but lost all my DLC, SaveData etc. RoGERO to the Rescue.
After I accidentally whipped my LT HD (I do not recommend doing this with a important HD unless you ave to) it took a few days to get Win7 back on it, the darn thing wouldn't boot Win7 install from anything, I had to sneak it in on a USB.
I had to pull my laptop hard drive and start up the PS3 with the LT HD so it would give me the select + Start option, bring it right to where it says hold select + start for 5 seconds to start the process. At this point I removed the LT HD and put back in my PS3 HD while I also have Rogero on my USB plugged in. It always starts, but gives an error (most likely because the HD specs etc are different, I was using a 500g HD from my lap top the PS3 is 360g)
However, at this point (AND ONLY THIS POINT) I could shut down, then restart, and it would give me the plug in your DS3 and press PS direction, leading me again to the Select + Start format option again. This time it goes through, and insted of just giving me the BSOD again, like SGK would, I got the system install and rebooted into ROGERO when it was all done.
I'm gripped I lost my GT5 Save Game with Speed Test and Motegy. I would really love it if somebody could hook up a save game after patch 2.11 with speed test ad motegy up on it.
