    at the moment there is no way to downgrade 3.51
    you would need to downgrade to 1.50 and then go to 3.51M33
    so u either gotta wait or trade psp's wit someone

    no! u r screwed. no url can help u. u are finished until u do something drastic, like get and install a modchip, or new psp. u were a noob to upgrade. u missed ur chance with the 3.50 downgrader. there is not even likely to be a 3.51 downgrader, because we have exhausted all of our last resources (3.03 downgrader ported from eLoader downgraders of 2.00, 2.01, 2.50, 2.60, etc., 3.50 downgrader ported from the 1.51 downgrader). however, people will be very determined to hack the PSP slim when it hits the books, and with thousands of people dumping the 3.60 firmware that will be released with the new psp, theres bound to be some sort of exploit. until then, u r stuck. done. bye bye, see u later. wave goodbye to homebrew. it may never come back.

    You have to wait 2 months, and np9660.prx is Sony's ISO loader.

    cant wait till sony decides to blow an efuse or something so that downgrading will kill a psp

    thats what microsoft did with xbox360 before anyone else even found an exploit in old kernels

    they cant do that. the way oru hackers do it is to make it so th e psp thinks its going to firmware X.YZ. and, according to something, numbers come before letters, so the letters indicate a higher version. at the last second the flasher changes it to 1.50, after its already too late.
