Serial hacker and modder George Hotz has successfully restored support for Linux on the PS3 (firmware version 3.21) by loading a custom generated PUP file.
"My ‘custom firmware’ [is] not any sort of version string change; I would have added something showing off the new features of 3.21, but oh wait, there aren't any," Hotz explained in a blog post.
"This can be installed without having to open up your PS3, just by restoring a custom generated PUP file, but only from 3.15 or previous. It's possible this CFW will also work on the slim to actually *enable* OtherOS; I'll know when my infectus gets here."
However, Hotz declined to name a specific release date and recommended that PS3 owners use a "proxy hack" to play online with 3.15.
"Note to the people who removed OtherOS, you are potentially turning 100000+ legit users into ‘hackers.’ There was a huge(20x) traffic spike to this blog after the announcement of 3.21. If I had ads on this site I guess I'd be thanking you," he added.
