Nighthawk MR2100 M2 wont turn on completely, red flashing light.

Hello all,

I currently have an M2 nighthawk, have had since april and has been working fine.

It went flat the other day so i put it on to charge and not it wont turn on. It gets to the white start up screen and shows the netgear logo. 2 of the 4 loading indicator circles are full and then it stops loading.

Have tried full reset, with battery in and battery out, let if drain full and tried recharging and still nothing.

Thanks in advance.
