This submission relied heavily on the work of
Santiago Rodriguez-Papa <contact at rodsan.dev>

Specifications:

*  Flash:          Winbond W29N01HVSINA         (128M  NAND)
*  Eth:            MediaTek  MT7621A            (10/100/1000  Mbps  x5)
*  Radio:          MT7603E/MT7615N              (2.4  GHz  &  5  GHz)
                     4  antennae:  1  internal  and  3  non-deatachable
*  USB:            3.0  (x1)
*  LEDs:
          White    (x1  logo)
          Green    (x6  eth  +  wps)
          Orange   (x5,  hardware-bound)
*  Buttons:
          Reset    (x1)
          WPS      (x1)

Installation:

Flash factory image through GUI.

This might fail due to the A/B nature of this device. When flashing, OEM
firmware writes over the non-booted partition. If booted from 'A',
flashing over 'B' won't work. To get around this, you should flash the
OEM image over itself. This will then boot the router from 'B' and
allow you to flash OpenWRT without problems.

Reverting to factory firmware:

Hard-reset the router three times to force it to boot from 'B.' This is
where the stock firmware resides. To remove any traces of OpenWRT from
your router simply flash the OEM image at this point.
