Troubleshooting on Downgrading in General

[SKLLMNKY]

Hello everyone, i am sorry if there is another thread with this topic, but i been having some trouble modding my psp. I wanna say last year around this time i stupidly installed the OFW 5.03 just so i can a demo, not realizing that it could not mod it at that time. Now that the new psp go came out, i wanted to see if i could take some games from my brother, which turns out i need another update for which i am not doing Because i finally decided to see if i can downgrade. Now the problem is, i keep trying different methods of doing this but so far i still have been unsuccessful.

Tools I have
--------------------
-Windows XP
-Psp
-4gb Sandisk Mermory Stick
-Pandora Battery
(idk if this matter)PSP battery charger
--------------------------------
Things about the psp i know
--------------------------------
its a slim 2001
OFW 5.01
the serial starts with HU2
---------------------------------
What i tried to do
-------------------------------
Skyline969's Pandora-free M33 LITE Installer
RainsUltraLiteMMS500v12
mspformat(everytime open this program it does nothing)
ChickHEN (or something like that)(can someone help me figure that out a little be more? i know it says you have to let the thumbnails load up and let it flash but i could never get it to do that. i know it can takes multiple attempts but i tried it 21 times)
pspgrader

Also when even i try to do the pandora battery method, do i put the mms in there first (after making it, and ejecting it instead of keeping it in there), then hold L, then put the battery in? All i ever get is the flashing power light.
--------------------------------------

Thank you for taking the time to read this i would appropriate all the help i can get. I just don't want to play Kenchou Bachou, Little Big Planet, Monster Hunter, and Beatarator without upgrading to the current OFW.

mspformat is a command prompt program so thats why it does nothing when you open it

and as for chickhen try putting in a UMD and see what happens (dont load the UMD just keep it in the psp)

So what are you trying to do? Downgrade, or hack the psp?

Thank you it works~ i am playing Super Punchout on my psp as i am typing this. I was also able to use a mame emulator.

So what are you trying to do? Downgrade, or hack the psp?

uh....i guess both... i want to be able to play psp and psx cso on mine. i want to be able to play these newer games without upgrading to a OFW.
