Is there another way to downgrade my PSP without using the GTA Liberty City Stories Downgrader?

Question

I have a Sony PSP with official firmware 2.82. I got it in January 2008. But I can't buy all the games I want to because of the costliness of them all. So I thought it would be great to download the games off the internet for lesser money. But I found out that I had to downgrade my PSP with a hacked firmware and pandora battery and the magic memory stick was the safest and the most effective way. I bought it but I found out that it doesn't work on my PSP official firmware 2.82. So now I have to Buy the GTA Liberty City Stories UMD Unpatched. I thought if anyone would know somw other way it would save me some money!!!!!!!! Please please please please please please please please please please please please help!!!!!!!!!!

Answer 1

There is another way to downgrade, but it also requires a game, which is harder to find than GTA LCS. If you have Lumines, then you can upgrade your Firmware to 3.5 and then use the Lumines game with files on the memory stick to downgrade it. I'd say you'd have a MUCH better chance just getting the GTA game, but get it used, because you may get the patched version.
