Finally, you can downgrade your 3.03 PSP to homebrew-friendly 1.50. You will need the following:- Unpatched GTA: Liberty City Stories
- 1.50 firmware
- 3.03 firmware
- 3.03 downgrader
[Thanks, Ben!]

This is great. Now I won't have to pay for games anymore.
I was only upset in the past because I had been left out of the piracy goodness.
No more.
And I am damn serious, too. I only care about this because I won't have to pay for games any more.

Please, can anyone help me? In the back of my PSP, where you put the UMDs, the number "IC6001" is shown instead of "IC1003". Is my PSP a TA-082 or a TA-086 PSP? I need to know this to downgrade my PSP succesfully. Thanks and please give me an answer!

It doesn't matter what motherboard it is, when you run it, it'll ask you if you want to patch it. If it does ask you that means two things. 1: You have a TA-082(if it doesn't ask you you have an original) 2:You hit yes.

If you want, pop by my forums at 5punk.co.uk and I have all the files hosted, along with a guide on how to do it.
I can also talk you through the process as a number of my members have all downgraded then upgraded to several different releases of OE

This worked a treat on my PSP (european).
If anyone didn't already know, you can play your original PlayStation One games on your PSP if you downgrade and then upgrade to 3.03 OE-C. There's tools around for ripping your discs.

Dark_Alex is a PSP God!!
Firmware 3.03 OE-C is fantastic, best of both worlds, Homebrew and PSP services.
Works on IC1003 motherboard
2.60>2.71>2.81>3.03>1.50>3.03 OE-C

Just downgraded from 3.03 to 1.5 using the gta lcs then upgraded using DAlex 3.03oe. Left the game inside and tried to load...Now it seems like the unit is bricked..So I will warn those who will try this. DO NOT TRY TO LOAD GTA LCS again it may happen to you too.

#32 asked a question that I would like the answer to also. Can you use Star Wars Battlefront 2 instead of GTA: LCS? I bought both today and my GTA is patched, but Battlefront has the 2.0 firmware. I read somewhere else that someone used the gigpack that had the 2.0 on theirs and it worked. Don't know if that is true or not.
Thanks!

OK. I have been trying to figure out this whole homebrew thing for a few weeks and I am very confused. I upgraded my original PSP too high so I bought a 2.81 version off craigs list. I successfully upgraded then downgraded, then upgraded again. It is now running Dark Alex's firmware 3.03 OE-C. NOW what do I do? Please help! :)
