Aura Kobo Aura blank screen, blinking line

[FelineFeral]

I'm having problems with my Kobo Aura. The battery was dead for a little while. I charged it for about an hour and it attempted to update but froze. I managed to get it to restart and go into restoring in mode. I was at the Setup screen when it froze again and the screen went blank with a vertical line of blinking black lines down the centre. I can get it to restart but it goes right back to the same screen.

Is it done for?

Thanks
