Dust Off The PSP And Update To M33

March1

With the announcement last week of a few big titles coming to the PlayStation Portable over the next 12 month, including Little Big Planet, Motorstorm, Assassins Creed and Rock Band, it will soon be time to dust off the old PSP living at the bottom of your closet. If it’s been there for a while, the firmware may be out of date. Like most PSP owners I know, you’re probably running custom firmware like Dark_AleX’s OE or M33 firmwares. Here is a short tutorial on updating your PSP to the most recent custom firmware release.

  1. Turn on your PSP and navigate to Settings >System Settings > System Information.
  2. If your System Software is 3.52 M33-3 or higher, skip to step 13.
  3. First you have to update your firmware to 3.52 M33. This will allow you to update to any of the later M33 releases.
  4. Download the 1.50 Official Firmware, 3.52 Official Firmware and 3.52 M33.
  5. Rename the 1.50 and 3.52 Official Firmwares to 150.pbp and 3.52.pbp if they aren’t already.
  6. Copy the M33CREATOR directory from the 3.52 M33 zip to the PSP/GAME directory of your Memory Stick.
  7. Put the 2 Official Firmware files onto the M33CREATOR directory on the Memory Stick.
  8. On your PSP navigate to Game > Memory Stick and launch 3.52 M33 CREATOR.
  9. Accept any prompts that appear. Once the program is finished, it will return to the XMB.
  10. Navigate to Game > Memory Stick and launch 3.52 M33 UPDATE.
  11. Accept any prompts that appear. Once the program is finished, it will prompt you to press ‘x’ to shut down PSP.
  12. Start up your PSP.
  13. Download the 3.52 M33-3 update.
  14. Copy the M33Update3 directory from the m33-333.zip to the PSP/GAME directory of your Memory Stick.
  15. On your PSP navigate to Game > Memory Stick and launch 3.52 M33-3 UPDATE.
  16. Go to dark-alex.org and download the latest M33 release. Also download the associated Official Firmware. (As of writing this, the most current M33 release is 5.00 M33-6 so download that along with 5.00 Official Firmware.)
  17. Rename the Official Firmware to <versionnumber>.pbp (eg. 500.pbp) if they aren’t already.
  18. Copy the M33CREATOR directory from the M33 zip to the PSP/GAME directory of your Memory Stick.
  19. Put the Official Firmware file onto the M33CREATOR directory on the Memory Stick.
  20. On your PSP navigate to Game > Memory Stick and launch M33 CREATOR.
  21. Accept any prompts that appear. Once the program is finished, it will return to the XMB.
  22. Navigate to Game > Memory Stick and launch M33 UPDATE.
  23. Accept any prompts that appear. Once the program is finished, it will prompt you to press ‘x’ to shut down PSP.
  24. Start up your PSP.

Now you will have a fully updated, custom firmware PlayStation Portable. Luckily, they have made the updating process in the most recent M33 custom firmware much simpler and can be done from the Network Update menu under Settings so you should have no issues keeping up with new custom firmware now and have no trouble installing it. I hope this helps all my PSP friends with outdated systems who cannot wait for some Little Big Planet PSP action. This is especially for you!
