Downgrader for PSP v3.50 firmware

There hasn’t been a lot to write about on the PSP homebrew and modding front for a bit, but this downgrader is pretty exciting. Now you can downgrade (which is like an upgrade) any PSP to play your own games and more…

This downgrader is for v3.50 firmware, and includes a port of the Homebrew ENabler (HEN) for firmware 3.50. It will automatically detect all known PSP motherboard types, and do the appropriate steps to ensure a safe downgrade.

To use this downgrader, you will need the following:

1. A PSP, upgraded to the official Sony v3.50 firmware. You should also set your language settings to “English”.
2. A legal Lumines UMD, either the EU (ULES00043) or US (ULUS10002) version. The original, Platinum, or Greatest Hits versions are all fine. Support for the Japanese version will come soon.
3. Sufficient intelligence and english language skills to be able to carefully and throroughly read the instructions.
4. It would also help if you’ve previously run the Illuminati Hello World, so that you’re familiar with how to run the Illuminati exploit.
