Flash Instructions:
D-Link normal OEM firmware update page
1. upload OpenWRT factory.bin like any D-Link upgrade image

D-Link Fail Safe GUI:
1. Push and hold reset button (on the bottom of the device) until power led starts flashing (about 10 secs or so) while plugging in the power cable.
2. Give it ~30 seconds, to boot the fail safe GUI
3. Connect your client computer to LAN1 of the device
4. Set your client IP address manually to 192.168.0.2 / 255.255.255.0
5. Call the fail safe page for the device at http://192.168.0.1/
6. Use the provided fail safe web GUI to upload the factory.bin to the device
