Hello everybody

This will downgrade your psp to 3.80 m33-5

Ok First to start things with you need another fat psp that is alredy been modded.

And you need a memorystick of 256 mb or higher if it's lower then it doesn't work.

And you need a fat battery not a slim battery
And your psp must be 78% battery

Download these eboot.pbp

340.PBP

380.PBP

Unrar these files and put it in a different map.
If thats done download this "disinter" a program that install the stuff for you

And install disinter to your pc.

Open disinister and choose 3.80 unbricker/installer
Load those sony eboot files (i think you know how to do that)

Plugin the modded psp and choose your psp drive.
And click Copy files to psp in Stage 1.

Go to Hellcats Pandora Installer for 3.xx
Press R and X to format and then press L / R and x to confirm it.

Then Plugin your psp again and go to stage 2 and click copy files.
This will take a while.

When it's done Go to game and then to despater del cementario.
Click x to start despater and wait untill it finished.

When it has finished go to Hellcats Pandora Installer for 3.xx again and click
L+X to copy the msiple.bin

When that's done go to Hellcats Pandora Installer for 3.xx again and click
0 to convert battery to pandora.

Now turn off the psp and take off the psp battery and the memorystick.
Put the memorystick FIRST in to the psp phat/slim and the the battery.

The psp will start automaticcly.
then press x to install 3.80 m33-5

Now leave the psp and don't do anything.
When it finished it says press x to shutdown psp, so do that, press x.

Take off the battery and put the charger in the psp.
Start the psp up WITHOUT the battery but the memorystick must be in the psp.

Go to Hellcats Pandora Installer for 3.xx and click [] (square) to return the pandora battery to normal one.

And just format the memorystick.

To go to 3.90 m33-3
download this file and put it in GAME folder.
