Nighhawk m1 keep rebooting can't update

[RamyJones]

I just got nighthawk M1 unlocked but it is not working with the sim.  It keep rebooting even I tried different sim cards, I did factory reset so many times, took the battery out so many times, even run power plug only still in boot loop .  I can't update either it won't download anything frorm server, error update everytime or keep saying CHECKING for ever...
