How to Install the Custom Firmware 3.90 M33-3 Update

If you checked out Dark-Alex’s website, you’ll find out that he has already released the latest update for the 3.90 M33 custom firmware. There’s still no news if he’s still planning to work on the 3.93 M33 custom firmware update since the 3.93 update has really no major features added. Just a support for a few games. So what was fixed on the 3.90 M33-3 update? Here are the changes.

* March33 NO-UMD driver compatibility has increased to support games like Coded Arms, Patapon, Harvest Moon Innocent Life and probably others affected by same errors.

There are two ways on how to install the update. But like all of my guides, there’s always a requirement to follow before you can do the update.

The Requirements

  • A fat or slim PSP installed with custom Firmware 3.52 M33-4 or higher.
  • A WiFi connection
  • A USB Cable

The Easy and Painless Way

Important: This procedure is only applicable to folks who have their PSPs installed with 3.80 M33 custom firmware or higher.

  1. Turn on your PSP and on your XMB, scroll to Settings then go to Network Update. Select your Wifi access point. The PSP will search for an update and it will automatically download it.
  2. After the update has been updated, it will ask you to run it now or execute the update later. If you want to run it now, press the corresponding button. If you have chosen to go back to the XMB, you can access it by scrolling to Game > Memory Stick > 3.90 M33-3 update.
  3. Run the update. After the update has finished your PSP will restart by itself.
  4. Congratulations, you now have a 3.90 M33-3 custom firmware. Go grab a soda or something.

The Not-So-Hard Way

This not-so-hard procedure was made for PSPs installed with 3.90 M33 or higher custom firmwares. If you don’t have 3.90 M33 custom firmware yet, follow this guide.

  1. Download the 3.90 M33-3 update from Exophase forum. Unzip the file anywhere on your computer.
  2. Connect your PSP to your computer via USB Cable. Copy the UPDATE folder from your computer to your PSP in this directory:/PSP/GAME
  3. On your XMB, go to Game > Memory Stick and then run the 3.90 M33-3 update. Watch the update do it’s thing.
  4. Follow the last step from The Easy and Painless Way procedure.

    You can actually access the VSH Menu on the XMB if you haven’t disabled it on the recovery menu. Changing the UMD Mode will be faster. Just press the Select Button. ;)

    Try this.

    Go into recovery mode [Hold R shoulder button down while turning on PSP]

    Now go to configuration then to UMD MODE and select Sony NP9660 NO UMD.

    Then go to ADVANCED then press X

    Go to ADVANCED CONFIGURATION and press X. (make sure everything in here’s disabled)

    Exit out of recovery :)

    try the iso/cso
