Here it is, a fix to keep Linux on your PS3 and still update to 3.21.
Last month, Sony announced that the next PS3 firmware update, 3.21, would disable support for the PlayStation's "OtherOS" feature. A lot of people never used the feature at all, so it was no problem. However, those that did make use of OtherOS support, valued the fact that they were able to run Linux on their console.
Though Sony didn't specify why it was disabling OtherOS (aside from mentioning it was for security reasons), many speculated that it had everything to do iPhone hacker George Hotz' recent revelation that he had hacked his own PS3. Hotz promised users that if they refrained from updating to 3.21, he would find a workaround. And he has!
Today he published a post to his blog detailing a custom fix he had come up with that allow users to upgrade to 3.21 without losing support for Linux.
"Here is a video demoing my "custom firmware". It's 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.
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.
No release date yet, use the 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."
