DGND3700v2 Firmware corrupt during update

hi all,
during update firmware of my DGND3700v2 something goes wrong.
So now when I power on my router, the power led remain red.

Searching on internet I found this link:

So I powered off my router.
I pushed the Factory reset button and I powered on holding it down.
Now power led and DSL led blink alternatively (power led red and DSL led green).

I connected the lan cable to my pc, setted the static ip address ( and, subnet mask and gateway and but nothing. router doesn't respond to ping.

Every issues with tftp method does not cure it.

Sounds like unit has bricked.

I have the same problem as posted here.
Is there a way to un-brick the router?

I have the same Modem. I upgraded to the latest firmware ver. V1.1.00.17_1.00.17NA. I'm unhappy with it. the modem works. I just have problems with setting static ip on the lan. The upgrade firmware button in the GUI, does not work, and I too tried to do the tftp2, and got the same result you did, with the flashing leds. So I don't think your modem is bricked yet. We just don't know the correct procedure, get it into the flash mode.

 had trouble where the power light was solid red. Luckily old router still worked so connected that again After a couple of hours on Google tryed this​8 but still had no luck


This did work though.

Down loaded the firmware for my DGND3700v2 from Netgear un zipped. Disconnected old router, connected DGND3700v2 with ethernet cable & opened internet browzer. typed in message came up about updating firmware. browsed for the firmware that I had already down loaded. Clicked on OK.


After the update had finished I could not log into the router, turned the power off & on, plugged the phone line back in now it works fine. Did not even have to set the router up again.


I only know a bit about the internet & computers so sorry if you need to fill in the gaps.
