A while ago I remember reading about how to get linux, or some other OS to run on a psp which was done via the headphones port because it had unrestricted access. However I've never seen anyone post anything about this getting blocked in any firmware updates (obviously not by sony, I mean by testers)
So I was thinking, using this port couldn't you access flash0 and edi the file to tell your psp you have FW 1.49, and then use the 1.5 update?
Or if that bit dosn't work, isnt there anything that could be done via the port?
I really regret upgrading to 2.7 :Argh: At the time I was like one of the first and no one had said anything about homebrew.....man Sony owned me big time :humped:
