With the release of the new Custom Firmware 4.01 M33 by Dark AleX, The U.P.M.S. Team found it prudent to update their own UPMSInstaller for the PlayStation Portable to version 4.3. The latest build of the application is now fully compatible with the newly released CFW.

Those of you not familiar with the app, UPTInstaller essentially helps clean your memory stick for a fresh install of any new Custom Firmware. This can be especially useful upgrading your memory stick from a working Pandora or UPMS stick.

Aside from being fully compatible with CFW 4.01 M33, the developer also noted that this version no longer needs to have fatmsmod.prx installed.

If you already have the new CFW 4.01 M33 installed, please note that using any other version of UPT or UPMS to install your Pandora Memory Stick will brick your PSP. Before running the app on your handheld, make sure to browse through the tutorial and other relevant documentation included in the file bundle.
