I'm a noob and I need help with a firmware upgrade!

Ok, I've basically haven't been in the homebrew scene for a really long time. I don't even remember my old username! Anyway, I just bought a 4gb stick but realized that I need to update the firmware in order to use the full capacity. Therefore, I figured, why not put one of those hacked firmwares, right? the only problem is I do not know how...could someone please help me out? I'm guessing the most recent one is the 4.01 m33, but I really have no idea.
BTW, I have a "fat" psp with the 2.01 firmware.
thanks!

You are in luck indeed, there are possibly 3-4 downgraders you can use on that firmware to get down to 1.50. From 1.50 you can upgrade to a Custom Firmware. Do you happen to own a copy of Lumines or GTA: LCS? You can use those games to downgrade.

Check out this page for the downgraders.

oh sweeeeet! I was reading up on some tutorials and found that to upgrade to the 4.01 i have to have at least version 3.52. whats the deal with that though?

Certain firmwares have updated security patches against downgrades so you have to be at a certain firmware.

The GTA: LCS downgrade will allow you to downgrade at firmware 3.03 and lower.
The Lumines downgrade requires you to be at 3.50.

I suggest just doing the 2.71 downgrade though, that would be an easy one for you to do.

so the 2.71 downgrader would work for the 2.01 firmware?

I think you have to be on 2.71 for that one. However if you choose that downgrade, be sure to check and see if you have a TA-082 Motherboard or not and do the correct downgrade.

yea I already checked, its not ta082. i think im going to do the pandora one...i cant find my 32mb card thats recommended for the 2.71 downgrader.

If its not TA-082 then you can do this tutorial http://psp.brewology.com/forum/viewtopi ... downgrader

Do you own Lumines or GTA: LCS though?

hhmmm. oh yea, i forgot to mention i do have gta...its how i used to play with some emulators.

check to see if it is the unpatched one -

ULUS 10041 - Unpatched/Can use to downgrade

ULUS 10041GH - Patched/Can't use

If so, use it to downgrade.

its unpatched. where may i be able to find the tutorial to downgrade with the gta game?

In that link in my first post, click on the downgrader for 3.03. There should be a tutorial there that will tell you everything u need to do.

hhmmm...the link with the 3.03 firmware update no longer has the file anymore. I am going to google it.

im almost done....

ok...ive been done for a while now, but i dont know how to open up my snes emulator...do I just drag the folder with the emulator into the game folder on the memory stick?
