I am also considering installing OtherOS(++) onto my PS3.
Relys' video looks wonderful; I can definitely see a really good use for Linux on a PS3!
However, I just wanted to ask whether I need to be on a specific CFW and whether I need to have either a CEX/DEX to use the setup/installation tools.
I had just formatted my PS3 via the recovery menu a few minutes ago for the setup tools, then I installed Setup_flash_for_OtherOS.pkg via the Package Manager, but when I booted the tool I encountered a 80010017 (error during start operation) error.
Currently, I am running 4.80 Rebug CEX firmware, and this is why I asked if I needed a specific CFW and type to successfully use the tools and get the beeping sound to tell me it's all worked out.
Any help would be massively appreciated
