OK re-formated the card, waiting on that.
Tried installing enso, thought I couldn't the first time due to base firmware on vita or something, it certainly failed when trying to install it off the site, but now when I use the repo version 1.1 it's saying it's failing to load the kernel?
Sorry @256BitLink ,did you manage to install Hencore on the PS Vita?
If you are successful,install modoru 2.1 and downgrade from the app.
I still don't understand if you want to downgrade or not!
