Pandora's Ultimate Magic Stick 3.80M33-5


New version of UPMSv3 - universal PSP Unbricker/Downgrader/Upgrader, also known as Pandora's Ultimate Magic Stick, Now work with DC ver4 (Dark_AleX’s), for installing CFw 3.80M33-5 and creating memory stick into a “Ultimate Magic Stick” for use with “Pandora’s battery” (jigkick). Works for both PSP, Slim and/or Fat, and 1 stick for all functions for Unbricker/Downgrader tools. Also available is the “UPMS_v3.pdf Guide” to help you get started and usage.

The Ultimate Pandora’s Magic Stick is the simple solution to easily accomplish any of the following:
  • Recover any bricked PSP (Fat or Slim) and install sony firmware or CFw M33.
  • Upgrade Fat-Slims PSP to CFw 3.80M33-5, with 1.50 kernel patch-Fat Only.
  • Upgrade Fat-Slims PSP to CFw 3.71 M33-2, with 1.50 kernel patch-2 -Fat Only.
  • Update to 3.71M33-4 are installed to the ‘GAME’ folder from the XMB.
  • Downgrade Fat PSP to Fw 1.50.
  • Upgrade Fat PSP straight to CFw 3.52M33 from Extended Boot Menu then install update 3.52 M33-4 from XMB, without need to downgrade to 1.50.
  • Boot up PSP using Ultimate Loader with support for choosing which Pandora’s you reach V1, V3 or V4.
  • Boot up PSP to XMB with UPMS inserted-Fat Only.
  • Boot up to a full FW 1.50 from Memory Stick-Fat Only.
  • Use PSP Filer and other tools (If it requires 1.50, can’t for Slims).
Note: This software is free, and comes with no warranty. Despite it has been tested and it has worked, there is some risk with any PSP operation that involves flashing, so please try this at your own risk!.

Only Memory Stick "Pro Duo" are compatible. Memory Stick Duo are not supported. Read more... for installation

I dont know how to degrade my psp version so i can use PSPtube


Sony has blocked access to homebrew since 1.51. The higher the version the harder to degrade.

The M33 installer is considered as homebrew.

You need to downgrade to 1.50 with a pandora's battery and a MagicMemoryStick.

Buy one at http://www.ebay.com/

The you will be able to use the M33 installer.

The "Data is Corrupted" is a hoax for sony to trick players into deleting the Very, oh so, Very UNcorrupted Application.

Downgrade psp 5.01 to 5.00 m33


If you are on psp 3000 series then you will have to live with it and buy UMDs for the time being.If not you can get a pandora battery and downgrade it to whatever you want.Since you are on 5.01 OFW I highly doubt your mobo is still trigger-able by pandora battery though.

Downgrade PSP from 3.80


It's impossible to downgrade your PSP from it's current version. I'm not quite sure why you'd want to downgrade, but maybe you should upgrade (If a version is available) again and see if you like that version better. ^-^
