The hardware flasher is only needed to downgrade 3.55 if you're not already on 3.55. As 3.55 is the highest firmware you can install this from. If you're already on 3.55, you don't need the flasher for installation of my pup.
Sweet. I'm on 3.55.2 Rebug. I'm gonna sit back a little longer and see where this goes. But either way, I'm happy with the progress you've made so far. I hope this will lead to your username on 4.00 lol Cheers
Update on "Debug Settings" integration into my modified 4.00 FW:
I've modified the xmb to act like CEX so its still usable as a retail console (the debug vsh uses different parts of the xml files so the xmb is more stripped down as it is for debugging - I patched this) Of course special debug xmb item will still be there
The XMB use DeViL303's XMB File Manager (I had to re-port it so it would be used by the debug vsh.self) The Debug Settings in my FW are as functional as the Debug Settings in Rebug's CFW. This is because the system is not flagged as a debug console.
There is still one major bug which I still need to find a work around - the ps3 crashes when it tries to quit any application and then requires a re-installation of the firmware (which is not good). Although pulling the power cord escapes having to re-install the firmware, it's not an appropriate fix. But on the other hand it does load games and play online. I'd appreciate to help to fix this, although I could try to find a fix myself, but two or more heads are better than one. The sooner I fix this the sooner I can release it.
