Tip

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

Well my psp at first had a version of 3.71(i could play iso games)... then i updated it to 6.00 (i can't play iso games)....now i want to make it 3.71 ....how is that possible?....could you tell me step by...


Hi There!
Honestly, downgrading the firmware is tedious compared to upgrading it. I would suggest you have someone who has the technical knowledge to do this. Failed downgrade could lead to a bricked psp. Which will render it useless. Some can be reflashed and will work back while some cannot.
However, you can purchase a Pandora battery for you PSP. Remember: You CANNOT downgrade your PSP with any firmware higher than 3.50 without a Pandora's Battery.
You may check this link for a self-help guide in making your own Pandora battery. This is for a PSP slim model.

How to downgrade custom firmware 5.51 to custom firmware 4.01


The easiest way to do it is to bring your psp to a game shop that modifies or downgrade/upgrade psp units. If you want to do it yourself you need to have a Pandora Battery and a genuine memory stick duo, download CFW files including Pandora battery files and procedures. Be aware that there s a risk of bricking your psp if you happen to make a mistake downgrading.

If you have a PSP-1001 or PSP-2001, you can downgrade your psp from 6.10 with a service or pandora battery. If you have a PSP-3001 you are out of luck.

You can create a service (pandora) battery and the 'magic' memory stick from any psp-1001 already running custom firmware. You can also buy them online, and if you look in the local classified ads website where you live, you can probably find people offering a downgrading service.

I cannot run through the steps here but tutorials are all over the net and sites like youtube.
