Are you referring to the colossus here? Boss, that would be gross!
I do have a complete backup of GoW III anyway.

For no points, there are several DIY jailbreak tutorials readily available on the net. I'd recommend these two:

1. http://www.ps3hax.net/2011/01/tutorial-how-to-play-backups-with-kmeaw-cfwpsn-without-risk-of-brick
2. http://psx-scene.com/forums/f118/cfw-kmeaw-ofw-3-55-gaia-2-05-ready-install-pack-77294/

Some digging on Geohot, Wutangrza, Waninkoko, and Kmeaw should give you an interesting read.
I'm running Kmeaw CFW + Kmeaw lv2 update on the slim console. Multiman is my backup manager.
The only hitch I've had is that I haven't managed to run my Black Ops backup as yet. Could be due to anything.....

NB: I survived the risk of bricking the console, so I have nothing to warn about that.


PS: I'm still looking for folks to lend me their Discs for a test-run ;).  Jangita? Any takers?
