I'm currently researching on a way to re-enable PSM support on 3.52 for PS Vita. The one thing that came across my head was to inject files from a lower firmware Vita, or to simply edit the 3.52 files to make them PSM-friendly. To start off my research, I am asking anyone with a 3.51 Vita just to dump their app.db and then PM it for me, so I can see whether there is any differences in the 3.51 and 3.52 app.db's. (This may also help me to track down any other files I need to examine.) I'd be extremely greatful for anyone who does this for me. Thanks in advance!
