1st backup memory stick. and put the UPDATE file and the pan3.xx folder on your psp.
then start the easy eboot installer, and select the option R+X, then it asks if you are sure and if you are, press L+R+X. then turn off your psp and turn it back on. (you might have to hold the switch up for quite a while for it to turn off).
then put the UPDATE file and pan3.xx folder back on your psp. once you do that, go back to your psp to the easy eboot installer in your game tab, and start it up. Press X to install full 1.50 on your mem stick. then after a while it will ask you to press L+X.
after you do that, go back to the game tab back to easy eboot installer and this time press the O button to make pandora battery. once you do that exit out and you just made pandoras battery and the magic memory stick.
then to unbrick/downgrade a psp. turn it off and insert the pandoras battery and magic memory stick and your psp should light up. and you will be taken to the XMB in 1.50 firmware.
