PSP downgrader for firmware 3.50 released

Posted by multippt

Fanjita and co (the Noobz team) in just a short space of a few days since their latest discovery of the Illuminati exploit have released their downgrader. This downgrader allows you to downgrade from the official firmware, 3.50, to lower firmwares like 1.50.

Why downgrade you may ask? Older firmwares have greater support for homebrew. This downgrader is tailored for firmware 3.50, so if you want to downgrade your PSP which is at a firmware lower than 3.50 (and higher than 2.80), you will need to update your PSP to that version. The downgrader will automatically detect the correct motherboard type to downgrade the PSP appropriately.

Note that if you downgrade a TA-082 (or tA-086) PSP with this downgrader, you may not be able to update to the latest version, since firmwares past 3.11 (3.30 onwards) will have checks that prevent downgraded PSP using new motherboards from updating (the problem is some corrupted registry values). However, you can use new custom firmwares (like the OE series).

To use the downgrader, you will need:
-A PSP, with official firmware 3.50. The language settings should also be set to “English”.
-A legal copy of Lumines, either the Europe or US version.

The instructions for using the downgrader is provided in the “readme” text file.

As with any downgrader, there is a risk that you may accidentally render your PSP unusable, so always read the readme.

In addition to the downgrader, they have released a port of HEN (Homebrew ENabler), which allows the execution of homebrew on 3.50.
