    Well first of all, in order to downgrade, you will need an 'UNPATCHED' version of the game Lumines. The new versions of Lumines wont work (only way to tell if its the 'Patched' version of the game, is that itll have 'Update to 3.51' on the disk). Check your local gaming shop and see if the got a used one for sale, if not its gonna be a whole lot more on e-bay.

    Thats the first step, once you get the game post back, but here's a link for "How to downgrade" a PSP. Ultimate Downgrading Guide

    Not without Unpatched GTA UMD (for firmwares 3.03 and below) or the Unpatched Lumines UMD (for 3.50 and below). I know its a pain, unless you borrow it from a friend, then u gotta buy it. I own both just in case. But gl on gettin the game

    Theres an Exploit within the game that lets you access the kernel mode in your PSP, basically bypassing the security to opening up a backdoor to the PSP. originally when the PSP had fw 1.0 or fw 1.5 on it, you are using it in kernel mode, when you have that kernel access to it, you can run your homebrew stuff on it. Its almost like using dos in windows, granting you full access to render any file. Hope that made sense to you and i hope i worded everything right.

    But as of the game, once you use the game to access 'kernel' mode, then you can use that access to actually downgrade from 3.50 to 1.5 (Full kernel access) then to cfw (custom firmware) which gives you the abilities of that firmware and plus have kernel mode on it to run you homebrew, built in ps1 emulator, custom themes, and backup copies of your UMD's (iso images).

    I tried 4 stores... None had it, The cashier at gamestop said that they dont sell it because of the whole psp thing. He also said its illegal even though no one gets caught.

    Is this Creditable?

    i highly doubt that, i found 2 in my gamestop 4 days ago, hes full of crap if you ask me. It is not illegal to have the game, and i highly doubt the feds gonna bust up in your house just because a custom psp... im sure hoping they got bigger fish to fry:) But unfortunately you might have to go ebay with it :(

    Nope, that is a 'patched' version (meaning they fixed the expliot which let use access the kernel mode). So its gonna be harder to find the original version,. GL on the search man
