Hi there, this is my first post in the Vita section I bought today a used Vita slim on 3.55. Unfortunately I'm a couple days late and there is now 3.57... I would like to activate my device to download Mimana Iyar Chronicle which I purchased thru the browser. Doable? I don't have a PS3 (I do have a PS4). I have VitaUpdateBlocker setup and working, doesn't seem to help. Thanks!
