PS3 Linux firmware -- gitbrew

Hello,

I wanted to try and get Linux on my PS3 tomorrow. I used to have it on when OtherOS was supported but then updated. So I now have Rebug firmware but want to upgrade to gitbrew firmware. I seem to remember him successfully supported the model CECHG03 which is mine a few weeks back. But I have no idea what firmware to use. CFW355-OTHEROS++-22GB.PUP is that the best from the gitbrew web site (since I use 3.55 Rebug)?

I have a 320GB drive inside so plenty of space. And I need to backup right? Just FTP everything across to my PC? Flash firmware then I'm confused as to the steps from there. Just enable otheros like in the old days? Or just use this

PS3:Linux - wikibrew I'm all a bit confused and don't want to brick my phat ps3. But I am comfortable with using linux, I use it nearly every day at work and have done since I was about 14years old (now in my early 20's).

Cheers for all the help.

http://git.gitbrew.org/~glevand/ps3/...OTHEROS_ON_HDD this helps a bit more but still need help on firmware cheers

So I managed to get quite far today.

1. I backed up everything via FTP..took like 3hours lol but I'm glad I did
2. Flashed the firmware CFW355-OTHEROS++-22GB.PUP did it in recovery menu just to be safe but absolutely no problems
3. Did the reformat drive thing in recovery menu all went well
4. Followed all the steps at http://git.gitbrew.org/~glevand/ps3/...OTHEROS_ON_HDD now I have petitboot running

I just need to install Linux all the drive is ready to go. Perhaps another day. Here is an image for you.
