Well, I have an asus VivoStick and I can't acces to the storage manually, so I erased all the data from that booting with ubuntu in a usb.
The thing that I've done is to paste the data from a flashed image with Batocera and let it runs.
It happens that it shows the main logo and then, very quickly appears the white second logo and the screen goes black and don't do anything.
What gone wrong?
