Nexus 6 5.1 upgrade endless boot loop

[Pug]

Keeps saying optimising apps, never gets out of the rut.

I have gone in and factory reset/wipe cache but still doing it.

Any options? Arrived from Motorola yesterday, is it going straight back or can I do something? Worked fine pre-update.

is it possible if it's not in developer mode? cos it isn't

Managed to sort it, was actually very painless once I got the google USB drivers working
