Custom Firmware 5.00 M33-3

Custom Firmware 5.00 M33-3. Fixes a bug in 5.00 M33-2 that made some games and homebrew to not work.

How to Install PSP Custom Firmware 5.00 M33 on your PSP

Now here’s what you’ve been waiting for, the simplest easy to follow guide that you’ll find on the web. Here’s how to install custom firmware 5.0 M33 on your fat and slim PSPs - no hack for the PSP 3000 yet.

Remember: do this at your own risk. I won’t be held responsible for anything that would happen to your PSP

The Requirements
* PSP with previous custom firmware installed, at least 4.01 M33-2 * At least 75% battery, connect your PSP to an outlet via the Adapter. * USB Cable

The Guide 

  1. Download the installer pack I compiled here
  2. Extract the file you have downloaded anywhere on your computer. 
  3. Connect your PSP to your computer and copy the UPDATE folder you extracted to ms0:/PSP/GAME/ 
  4. On your PSP, go to the XMB menu and scroll to GAME > Memory Stick and run the 5.00 M33 update. Follow the onscreen instructions. 
  5. After the installation, you’ll be taken back to the XMB menu.


Ensure that all parts are in the same folder.

Winrar will automatically extract the needed parts from all the files and join them up.

How to combine game parts:

Step 1: Make sure you have all parts of a game in the SAME folder, or all on your desktop
Step 2: Open up the FIRST part of the file and extract it to wherever you wish
Step 3: The rest of the parts will all come with it

Q: What is a .rar file?
A: A .rar is a compressed WinRAR file. To open a WinRAR file you must file you must download WinRAR.
A: A .cso is a compressed .iso file.
Q: "My PSP shows 'Corrupted data' when I put a game on my PSP"?
A: This means that you did not extract the file in the .rar.
Q: Every time I try to start a game, my PSP shows The game cannot be started.(80020321)?
A: This means you either do not have custom firmware(OE, M33), or you have the wrong UMD Mode(Normal -UMD required-). Try switching your UMD Mode to 'M33 driver: NO UMD-)' or 'Sony NP9660: NO UMD -)' for best results. If you do not have custom firmware(OE, M33), you must downgrade your PSP using a 'Pandora's Battery' and 'Magic Memory Stick'.
Q: My game freezes at the start menu/during game play?
A: Try switching your UMD Mode from 'M33 driver: NO UMD-)' to 'Sony NP9660: NO UMD -)', or vice versa.
Q: What does it mean when you say the Update is ripped?
A: This has nothing to do with the game play at all, it is only the firmware update that comes with the game, but since you are running an ISO/CSO instead of a UMD disc, it is not necessary.
Q: How do I from MegaUpload?!
A: If you're a premium member, type in your user name and password to get an instant clickable link(no size limit). If you're a free member, type in your user name and password and the image verification code and click 'Download'. Next, click 'Free Download' and wait 25 seconds and then click 'Download' again to your file(500MB limit). If you have no membership, type the image verification code and click 'Download'. Next, click 'Free Download' and wait 45 seconds and then click 'Download' again to your file(500MB limit). accelerator's only supported with a premium membership, sorry!
