Downgrading versions higher than 2.8?

[masqueofhastur]

I looked through the guide, and since it was last updated a year ago, it only has info up to 2.80. What's the downgrade status for firmware versions past that?

2.80 was the last one that didn't need anything extra

After this one is 3.03 downgrader wich requires an unpatched umd of GTA LCS (how to know, it comes with update 2.00 not 2.60, and no greatest hits)

Then 3.50 downgrader wich needs a lumines UMD to work, sony patched it and released a lumines that required 3.52 update, but there are more unpatched ones, not like GTA

These two required a game, because the exploit was on the savedata

3.51 up to infinity, pandora's battery, wich works accesing some sort of service mode with a modified battery (yep your battery contains data), and a memory stick wich installs 1.50 firmware, or 3.71M33 for the psp slim and lite

check the link on my sig, I couldn't believe that all the info about homebrew is on wikipedia
