    I really need help with this same exact question. I didn't know what I was doing and upgraded my black psp to a version 2.81, and now I don't know how to downgrade. I gave away my GTA, so I cannot use that method of downgrading to a 1.50

    upgrade to 3.03 and then use the 3.03 downgrader to get to 1.50

    If you have an 2.81 then there is no way to do it without gta.Upgrade to 3.03 and use gta to downgrade to 1.5.

    No don't do a network update cause it cold update yor psp to the latest version which is 3.50.Just download the 3.03 update and place it in your memory stick and run it from there.

    I think after you download the file you need to rename it to EBOOT.PBP if im not mistaken.It would be easier if you had an access to a pc cause its kind off hard to do this kind of stuff using your psp only.

    Just go here and download the PSP up and down all in one. Run this program on your computer with your psp connected to your pc...this will walk you through the whole process as well as download all programs/updates for you. Hope this helps:
