Nighthawk M1 bricked mode?

Hey guys,

So I purchased one of these today after being advised that I could try it on a different network and return it if I wasnt happy.

Had it setup within in mintutes. However while messing around with the mobile app, i accidently tapped on the "use 2.4 and 5g combined" icon. The unit then attempted to reset itself, but has been stuck in what i would best describe as a bricked mode. main lights (screen, power and trasnfer) are on with the orange light intermitently flashing. I've attempted to reset it multiple times to no avail. I've removed the battery, sim, put it on charge and attempted different button combinations. I've attached an image.

Any ideas on how to get it back up and running?

Cheers
