On the way home today, i went in to the mall, and i though no harm in asking a reseller of the psp if he know how Sony flashes there psp's... i did not believe i would get any response at all, but what the hell, you don't get dumber if you ask.
To my great surprise he told me that his coworker had flashed the psp whit a USB cable.. i know it might not be proof to you guys, but its proof egnuff for me! he also said this was official Sony stuff
He told me he did not know much more, but if i came back at 16:00 (local time for me) then his cow worker would probably show me how, Unfortunately i had to catch my bus at 13:20 and i could not stay much longer.
anyway i will go back to the same store to see if i can get a hold of this flasher, it would mean downgrades for everyone every firmware any time.
if i cant get any software out of this guy at the store i have a theory in how we might get to know our beloved psp more, if someone created a software that read all signals from the psp while it booted it might lead to something.... or it wont that depends on if the PC tells the psp to boot into a re flash or if the psp asks the PC for re flashing files
