Cant we get linux to boot up and write to flash0 from there?
Just an idea.
-DarkJEdi | I believe that you'd need more than that dump to successfully do anything with the PSPs firmware, some kind of authentication or 'key'.

So, how do we do that? Well, we can't at the moment. And as far as I can tell, people sorta tried tricks to get round it, but nobody really mentioned WHY it was read only.
So, I got thinking, about how files are read only. Im no developer, but importat read only files, like the SAM password files on windows, are read only by having them constantly open, giving the 'is being used by another person or program' error.
Anyways, Im thinking there has to be somebody here who can figure out how the files are read only. If we know that, then we can be on our way to getting round it. | Please there should be a door in your room, walk out of it and go have fun. Leave the computer. |

| | | | I have a question for you. How the upgrade has such access to this admin mode. There is a code in the upgrade to launch the admin mode?
If anyone can launch the upgrade which is on ms, anyone could launch another thing containing the access code and the signature of the original upgrade file ??
ps:sorry for my bad english* |
