To downgrade do the following: (read entire post first! notes @ bottom) or go to http://blogger.sahaskatta.com/2005/09/downgrade-psp-v20-to-v15.html

Create the X://PSP/GAME/UPDATE directory if it doesn't exisit.
Copy EBOOT.PBP (v1.50) into X://PSP/GAME/UPDATE folder.
Unzip the PSPdowngrade.zip package and open the folder.
Copy overflow.tif into X://PSP/PHOTO/ folder.
Then copy h.bin into the root folder. (X://h.bin)
Finally copy index.dat into root folder as well (X://index.dat)
Make sure your AC adaptor is connected.
In your PSP enter the Photos section, which will launch a little app.
You will need to wait ~30 seconds and then restart your PSP.

Then finally Game Menu and launch the v1.5 updater (downgrade).
Follow instructions and then at 99% an error should popup.

Thats normal so just restart the PSP and it should show an error.
Now restart the unit one more time and the PSP should be ready.
