    Hi Gurus
    I accidentally upgraded my PSP to OFW 4.05, I want to downgrade it to CFW 3.90-m33. I have a pandora battery and created a magic stick, but when I tried to use them, the power light, wifi and mem stick light goes on, but it does nothing. after a few seconds all the lights go off. HELP! PLEASE...any ideas.
    Thanks in advance!

    hello i am going to tell you how to get your firmware 4.05 downto firmware 4.01m33-2 with out a pandoras battery

    first you will need to down load psp pandora deluxe v1.0 make sure3 it is v1.0 and not v.04 or it will not work
    then download psp firmware 1.50 ofm not cfm or will not work and firmware 4.01 ofm not cfm or will not work

    when you have them downloaded i would put them in folders on your desktop

    plug your psp in to your computer and copy all your stuff off your memory card and save it to a folder on your desktop called psp backup

    then open up the psp pandora deluxe v1.0
    when it comes up you should see were it says load psp firmware files
    click on load 1.50 and 4.01 when you do that a box should pop up go to your desktop and the the folders you made and click on the firmware files

    back to the pandora next to the firmware you will see that the install is now upen click it on both firmwares

    when you do that the install options are now open click on the 1.50 downgrader and the despertar cementerio v6 (4.01m33-2)

    when you click on them the padora button confiuraion is now open were it says dcv6 set the button to the l

    then where it says other options click it then there should be a box to click that says copy the 4.01 m33 1.50 addon click it

    then on the memory card options click on format that away when it formats the memory stick it will gave you the iso folder and others
    then were it says psp drive put in your psp drive letter

    then push start it will take a few mins and it might look like it is not working but it is

    when it is done unhook you psp and turn off the power then turn on the power and hold down the l trigger button and a scaren will come up that says
    insatall 4.01 m33 or install 4.01 ofw and others make sure it is on the 4.01m33 and push x

    then it should install and now you wave psp cfm 4.01m33-2

    Sorry, to budge in but the only way to get custom firmware is use the pandora battery. There are plenty of guides out there.

    Yes, it works. Yes it can play iso or cso games.

    Did you upgrade to 4.05 or did you got it when you bought it.

    the steps from Kanelita appear like they are for a Phat PSP not slim PSPs... do you have a slim?

    if so you need pandora battery... follow this tutorial:
