Gh0st’s UPMS Installer packs a collection of useful software tools for converting to & from a Pandora’s battery, writing the IPL to your memory stick, and creating the Ultimate Unbricker/Downgrader solution.

Easily achieve any of the following when combining both the Pandora battery and Ultimate Pandora Memory Stick (UPMS):

* Upgrade a Slim to 3.71-2 M33;
* Upgrade a Phat to 3.71-2 M33 w/ 1.50-2 kernel patch;
* Upgrade a Slim to 3.80-5 M33;
* Upgrade a Phat to 3.80-5 M33 w/ 1.50 kernel patch;
* Downgrade a Phat to 1.50;
* Upgrade a Phat straight to 3.52 M33 from Extended Boot Menu, then install update 4 via XMB — with no need to downgrade to 1.50;
* Boot the PSP using Ultimate Loader with support for choosing which Pandora you require — V1, V3, or V4;
* Boot to the XMB with the Pandora battery inserted (Phat Only);
* Boot to a full 1.50 firmware from the memory stick (Phat Only);
* Use PSP Filer and other tools;
* Upgraded a Phat or Slim to 3.71-4 M33 from the XMB with the update;
* Recover any bricked PSP (Phat or Slim).

Of course you’ll require the corresponding [official] firmware EBOOT(s) depending on your selection. Copy each EBOOT to the root of your memory stick — 1.50 (rename to 150.PBP), 3.71 (371.PBP), 3.80 (380.PBP), and also a second copy of 1.50 named “UPDATE.PBP.”

To start using UPMS Installer:

1. Ensure UMD Mode is set to “Sony NP9660.” Hold R-Trigger while booting to enter the recovery console, go to Configuration, and set the UMD Mode there.
2. Copy UPMSInstallerV3.cso to the ISO directory on your memory stick; i.e.) F:\ISO or /Volumes/PSP/ISO
3. Browse to the XMB game menu and launch.
