Hay i am a bit of a n0ob n i donno much but i was thinking and came to this

Warning: Havnt tried this do not blame me for casue of bricking or anything related. (just an idea) I will try it when i grow some balls. Soon

1.you get 2 mem cards (i know what your thinking but this is a bit defferent to the hot swap so dw) u put eboot 2.6 on one and 1.5 or 2.00 on another.

2 then you run the 2.6 like normal BUT without the ac adaptor OK.

3. You then go through all the crap intill it says please connect the ac adaptor THEN you put the psp to sleep by quickly flicking the switch to off and then let it flick back the screen should then go black.

4. This is when you switch the cards (you would think this is more safe because it is sleeping but i donno havnt tried it) so you switch the card to the one with the 1.5 and put in the adaptor and turn it back of sleep every thing should go fine from there it should start loading the updade witch is really overiting ang putting in an old version.

must WARN you again i have not tested this just an idea i hope it works i bacicly thought of this to help the people who have the usb problems with the other 2.5 downgrader. I will son try this and post. again i am 13 years old so this is probs a bad idea
