I have a 3G model Vita on firmware 3.36 I am following the instructions here: http://wololo.net/2015/07/19/how-to-install-psm-dev-for-unity-on-ps-vita-firmware-3-20-and-above/ I just want to get my Vita and PC ready for now in case Rejuvinate ever amounts to anything But I wanted to ask, does anyone know if these instructions will corrupt/delete any of the information currently on my Vita? I have a lot of stuff on there. Do I have to backup my Vita then restore from the Content Manager? Or can I send that Dev thing to it without having to "merge" it with the rest of my files? Also, I don't understand the e-mail step. When I open it in Thunderbird, it's already addressed to a test address at gmail, how do I modify it to send it to myself? And finally, what if I don't have a game that needs an update?
