3.50 Downgrader by Noobz

YOU NEED LUMINES I, NOT LUMINES II

Here's a video of me successfully downgrading a 3.50 PSP to 1.50.

This is by far the fastest and easiest downgrading I've done so far.

Good job Noobz!!

And just for clarification, this is just a video of me enabling 3.50 HEN using the exploit that was found in Lumines and then downgrading to 1.50. Nothing more, nothing less. This is more of a video just showing that the downgrader does indeed work.

But here's a video of me setting up the files


For further information, go to and/or

And just for quick access...here's a guide on how to downgrade.

Wait, when I press start, it says please put in a nickname, of some kind.

That means you didn't install the files properly. The screen is supposed to flash as shown in the video.

Refer to the tutorial vid that i have linked in the description

does that mean i cant downgrade my psp slim 3.72 version this is only for 3.50??

For slims you'll want to make yourself a Pandora/Despertar del Cementerio v5 as mentioned above. You need an already hacked PSP to help you to make one.

can you pick what firmware version you want it to be downgraded to or does it go straight to 1.50.
shortboy (April 6, 2008 at 4:21 pm)
For older downgraders they all go to 1.50 because that's the initial firmware that one must start on in order to be in a custom firmware.

For newer downgraders such as Pandora/Despertar del Cementerio, you can go straight to the current custom firmware which is 3.90 M33-3.
