It took me some time to figure out how to install this update on my PSP, because of a small misunderstanding.
When you download the Update #4 (M33-4) file from any of the PSP sites, it is not the installer.
This is perfectly OK, because the M33 Creator is doing it’s work in the background. Look into the applications menu again, and you should see another application called the “M33 Upgrade 3.52”.
After you have run it, you will be shown a disclaimer and asked to press the X key to confirm.This file will only patch an existing M33 3.52 firmware PSP with the new version.To save people a lot of work, I decided to write this tutorial which includes all the necessary files in one location.The archive avaliable on this website includes the M33 Creator, 1.50 and 3.52 official firmwares, and the M33 Update #4 patch. You can download it from one of the following website: M33-4Mirror: M33-4Extract all the files onto your PSP in the PSP/GAME150 folder.It has to be the GAME150 folder, otherwise the upgrade file will not start.In a few seconds a message will tell you that your PSP has been patched successfully, and pressing X will turn off the PSP.
