you dont need to use the Pandora's battery you can do it via the menu:)

or i believe Despertar del Cementerio v3 will do the trick:)

there is no firmware as of this date that cannot be downgraded via pandora battery method 3.90m33-3 can be downgraded to 3.80m33 use the umps i posted above and you will have an ultimate pandora memory stick which will let you install any custom firmware you want on any psp period it just has to be installed on a memory stick using a psp that already has custom firmware

Wasted420 I'm sorry for giving up before but as the guide said
The battery and stick combination is now capable of doing all the following:
1. Upgrade a slim to 3.71-2 M33.
2. Upgrade a phat to 3.71-2 M33 w/1.50-2 kernel patch.
3. Upgrade a slim to 3.81-5 M33.
4. Upgrade a phat to 3.81-5 M33 w/1.50 kernel patch.
5. Upgrade a phat to 3.90-3 M33 w/1.50 kernel patch.
6. Upgrade a slim to 3.90-3 M33.
7. Downgrade a phat to 1.50.
8. Upgrade a phat straight to 3.52 M33 from Extended Boot Menu then install
update 4 via XMB with no need to downgrade to 1.50.
9. Start up a psp with Ultimate Loader with support for choosing which Pandora
you require V1, V3, V4 or V5 (by holding down the L trigger).
10. Boot to the XMB with the Pandora battery inserted.
11. Boot to a full 1.50 firmware from the memory stick (Phat Only).
12. Use PSPFiler and other tools (if it requires 1.50 slims can't as there is no 1.5
kernel).
13. Upgraded a phat or slim to 3.71-4 M33 from the XMB with the update.
14. Recover a software bricked psp (phat or slim).

As you can see it doesn't say anything abou "DOWNGRADE FORM 3.90-3 M33" Is this only for Upgrades if not How do I downgrade it, if the guide is only for upgrade it
Than you man and thank you for been patience with me, but is my first time and i'm super stuck

ok once you create the stick you will see each when you boot into pandora mode it will give you the option to chose which pandora you want to load you can choose the 3.80m33 option it will format you flash0 and install 3.80m33. pandora erases the firmware on the psp then installs what you tell it to in most cases people are upgrading hence the term in the guide but in your case (really everyones case)the term would be incorrect so every time it says "upgrade" just pretend it says "install" or "flash"
