    So, is the only reason you can't downgrade from a TA-082 is that you can't update it to a firmware that has a downgrader for it? Or is it an actual hardware restriction formed by sony? Because for the 2.5/2.6 downgrader, you have to *update* to 2.6 and then downgrade to get 1.5, right? You can't downgrade from the original firmware on it, is that it? Flame me if you wish, call me a noob or whatever because I never updated my 1.5 and I just wanted to know what all of the fuss was about with downgrading... if a downgrader came out for 2.71, would TA-082 owners be in luck? I'VE WANTED TO KNOW FOREVER! lol

    From what I hear the ta082 boards require a higher voltage to power up (when you slide the power button up it sends power to the board) From what I hear 1.5 sends less than 2.6 so it doesnt get enough power to turn on. Thats just what I read it sounds confusing.

    It has to do with the 1.5 ipl being blacklisted on the board. I believe that volatge change also has something to di with it, at least thats what Ookm said when he realised that the Up would not work on 082's. But im not sure exactly.

    i knew that but i was wondering what does the power voltage have to do with messing up the downgrade?

    If i'm correct, the downgrade isn't the problem in the voltage respect. If this blacklisting didn't exist, then the downgrade would still run correctly, right down to 1.5. So you would have a 1.5 PSP. The catch is that the 1.5 firmware, particularly the part managing the power, wouldn't/doesn't send enough power to the motherboard to boot it up, as those motherboards require more power than the ones that can be downgraded.

    So the downgrade runs perfectly fine. The problem is that 1.5 doesn't know that there is a different motherboard, which requires more power, and doesn't send enough power to it to boot it up. Seeing as you can no longer get enough power to boot it, you now have a sort of brick. The firmware and BIOS are fine, but your motherboard just isn't getting the power it needs.

    Which begs the question. Could a 2.6 W/ these motherboards perhaps downgrade to a custom firmware? One which would send the correct amount of power to the motherboard? That way, the blacklisting can be worked around, as can the power restrictions.

    Of course, that's just my thoughts. I know very little about this stuff.
