KaKaRoTo: I also don’t plan on doing any kind of homebrew development, it’s not challenging or motivating enough.

KaKaRoTo: My main and probably only reason for working on the PS3 was the curiosity, the challenge, the fun, and most importantly the knowledge I would gain from this experience. The satisfaction of achieving something you’ve spent hours debugging is incredible, and the knowledge you gain from it has no price.

Kacex asks: Well, my question regards homebrew… While at the moment we cannot run unsigned homebrew, when those apps are signed, PSN friends could see that I’m running these apps, therefore Sony could too, and that could potentially lead to ban… Is this correct? So basically homebrew developers would have to implement some kind of stealth way for someone to use it, could that feature be implemented on this kind of homebrew? And I don’t mean “Look I’m playing Lemmings”, something that doesn’t share the current game being played for those apps.

KaKaRoTo: For now, the people who want to install custom/modified firmware, or to jailbreak their machines, should be smart enough to know that they are breaching the license agreement with Sony, and that it’s Sony’s rights to prevent them from accessing their service (PSN) if they wish to. If they want to take that risk, they have to accept the consequences. In my case, I never used my jailbroken PS3 to connect to PSN.

Brandon asked: You said before that you want to be responsible and not allow piracy with something that you do, yet it is known that you can use PL3, the payload you developed, with backup managers, even though it could have been made to not support it. Why is it that you were willing to allow it with the payload, but not with a firmware modification?

KaKaRoTo: Thanks a good question Brandon. The reason is simple, PL3 was an incremental modification on a payload that was already released by the psjailbreak team, which itself already allowed backups to run. I didn’t implement backup support into PL3, it was there, and I just kept it there. With this new MFW, not only is it new and there is no already available solution for backups (so I have no reason to actually spend time to add support for it) but also, allowing backups (or piracy) to run means modifying the LV2 kernel, and doing that can be dangerous because a single mistake could lead to an irreversible brick of the machine and I’m not willing to take that risk, not for my PS3 and not for the PS3 of those who would use my tool to create their own modified firmware.

You need to have a goal before you start. Here are some tools released by fail0verflow to use:

He Knew where to start because he used sonys original 3.55 and just made some changes. This MFW is not a "CFW" Becuase it uses sonys orginal patch. CFW us one that is made from scratch.
