I'm using the Maidumptool and it's quite confusing. First I chose the option to extract and decrypt. Then it started with a note saying the Party cannot be opened. Then I chose to proceed, it opened the SFxT manual. The Vita then turned off, so I opened it. I opened the mai tool and it proceeded to open alternately with SFxT like switching tabs, showing logs of what it's doing. Then it says extraction was completed, so I open mai again and chose to install the game, and no matter how many times I clicked it, it showed me an error saying the game could not be installed. Checked the folder size on molecularshell and the file size was barely 300 mb which probably means the dump failed.
I tried Persona 4 Golden next, it opened up the manual, then a second or two later, Vita crashes(error with asterisks for loading).
