Info:
I have tested the firmware on my PHAT PSP and all have worked. My model is a IC1003. I have not tested the firmware on a SLIM.
I use a pandora battery and a magic memory stick [jigkick] (128mb) to place 3.71-M33 firmware on my PSP
After i check the system setting to make sure I have 3.71-M33 on my PSP then I use the M33-2 firmware to update to that version. And then I continue to upgrade till I have the most recent version. I am using 3.90 M33-3
example:
connect PSP to your PC, then open the folder "Custom Firmware 3.71 M33 Update 2" and copy the UPDATE folder and place it on your PSP in the folder PSP/GAMES/ after you did that it should look like PSP/GAMES/UPDATE Then disconnect the psp from the pc, Go to the games on the psp and select the memory card. from there you should be able to select upgrade, follow the onscreen instructions. After that go to the system setting, system information and it should show you should now have 3.71 M33-2

PLEASE HELP
I just bought a 4GB memory card (official Sony one) and it shows that it's 4GB on the PSP but PC says its 1.6GB!! I formatted the card using the PSP but then my pc shows that's its unformatted. If i format on the pc the pc shows that its 1.6GB.
My PSP has firmware 2.01. I read that you have to downgrade to 1.50 firmware using eboot and MPHDowngrader and then upgrade to 4.01 M33.
Anyone know how to downgrade from 2.01 to 1.5?
