Black screen after update

[fspimenta]

Hi, I turned on my homemade Arcade with Raspberry PI 3 after a few days without using it, I had a recent version of Recalbox, I had just re-installed it a little while ago. But I was warned that it had an update and I selected to update in the menu, after that, I got a black screen and no sound, even after leaving it on for several hours... The card is initializing the wi-fi because I can access via ssh and through the browser too, but on the equipment screen only an image appears with "ExperimentalPI" when it starts and then nothing else.
I use a SVGA monitor with a hdmi2vga adapter...Does anyone know how to solve? Is it possible to rollback the update?
Thanks.

@zing , this tutorial helped me, I think the origin of my problem was no space left on the sd card, because my backup did not fit back on the SD card after creating a new image, maybe the recalbox 8 is bigger then the recalbox 7... anyway, I will consider moving the share folder to a usb device. Thank you.
