Hacking Questions about installing PSM Dev on my Vita

[Cyber Akuma]

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?

No, it won't corrupt any data as far as I'm aware. I've installed it too many times and it hasn't deleted or corrupted a single thing!

You have to forward the email to yourself; you don't modify it as is.

I tried that but it seemed to mess up the attachments and the other contents of the e-mail

That's wierd. It doesn't do that for me...
What do you mean by it messes them up?

It seems to just toss the attachments in there and not in the order or with the text of the original e-mail.

When you email it to your Vita, can you still click the attachments?

Finally got it after much issues. I do have one last question though, since I tricked it into installing by using the update of a cartridge game I had just bought (to be specific, I used Freedom Wars), can I now update said game normally, or can I not install the original game's update it anymore?
