I've got a 1st gen Nexus7 .

It's stuck at the coloured circles phase of bootup.
It's been like that all through the night.

I suspect it's taken an auto upgrade of some sort, but I can't tell what.

Anyway, there is something coming out which bricks these devices - so beware.

My device is out of warranty period, so I don't know how I'm going to get it fixed.

Best of luck.
