I've installed UPMS Installer (Sapphire) on a memory stick and ran all the menus in the program. I did the menu 3 install with the left trigger for the dc3v folder installation. Now I'm looking at menu 4 and if I do the 352-M33, 371-M33, or the 380-M33 install, I go the system information in my psp and it still says 3.90M33-3. I've tried the whole holding down the left trigger to start the dcv3 folder and nothing happens. Is there something else I'm not doing right? pandora's battery to run this or in normal mode? I've been all over these forums and can't seem to find a good one that explains it all.

I like the program IRShell and the functions in the past that I used with it. My understanding from some of the forums on here, is that IRShell 3.9 does and does not work that great. I want to downgrade to 3.71M33 to use IRShell 3.8.
