Ok, sorry for double posting, but I just finished following the directions, rebooted the system, and now it's... stuck loading the card. I don't think this is a faulty card, as I got a samsung evo3 128gb, and the PS2VITA is also new.
Basically it's like it's not detecting it...
Ok, so I tried using a different SD Card, and tried rebooting it, and the Vita screen kinda froze. It's black but still displays the status bar at the top. The reader is clearly on and blinking, but it's taking way too long for it to do anything...
It rebooted, and it's taking a long time (a few minutes) to read it, and I think it's just defaulting to the original memory stick, and I don't know what's wrong. Is it possibly the SD2vita card then? Do I need to send it back?
