Warning: Be aware this PS3 CFW is still under development, and like all PlayStation 3 Custom Firmware should only be installed if you are aware of the risk of possibly bricking your console. Although not a requirement, ideally it should only be attempted if you have a backup of your PS3 NAND / NOR and a hardware flasher available.
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 the
REX Rebug CFW 4.21 which is the most stable and most successful of the moment. He added the Debug menu and Rebug Package Manager for our greatest pleasure.
Some files from firmware 4.30 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.

with the xillia release is coming near, I hope mamu is still there to help us with undub job 
...
I popped out the HD from my laptop & put it in the PS3, I was able to get the screen that tells me to have 4.40 on a USB and press select & start then again holding them.
I put my PS3 HD back in then held select start, it went through the format process all the way to 100%, the system then reboots to the Blue Screen of Death.
I can get it to format the HD booting with my laptop HD and the blue screen only comes with the PS3 HD, it will also give me the "Cannot start the appropriate system storage was not found" error if I boot sans HD. I'm thinking SGK fried my HD so I'm going to see about buying a used laptop hd at a PC shop later today.
