I've got my PSPGo running on cfw 6.39 PRO-B9, and I can't get any of the plugins to work. I've followed all of the steps exactly as in all of the tutorials, but my plugins just aren't working. I'm trying to get any of the mp3player plugins and the hold.prx plugin to work, and neither one are doing anything. First I tried them on cfw 6.20 pro-b9 and they didn't work, so I thought that maybe I needed to upgrade the firmware, but 6.39 isn't working either. Can anyone give me some advice? Thanks.
