Can't flash UI to Netgear DM200 modem

Please dont throw working lantiq xrx200 hardware away! Its just the firmware you have to reflash because for some unknown reason you have disconnected the power of the router inside of the upgrade process - a workflow that its never done on any router, independent of the OS running on it.

Your ISP requires VDSL vectoring support? Then follow my howto here:

Howto: Updating the Lantiq XRX200 devices with latest DSL vectoring firmware

Because i had to struggle around some time i would like to release a howto for updating the firmware. Most information is available somewhere over the internet. Here a more combined version. This howto is for GNU-Linux OS. I dont care about closed source OS like Windows, MacOS, ... In general i would recommend to use the AVM Fritzbox 7490 firmware to get the firmware from. Reason for this is because this Router get most frequent firmware updates. It also have Annex A and Annex B firmware insid…

I checked the wiki of your device:
U-Boot 2010.06-12284-ga4702df (Mar 03 2016 - 13:07:38)
[...]
Client starts...[Listening] for ADVERTISE...TTT
Retry count exceeded; boot the image as usual

It looks like a propper u-boot. Please defenetly dont throw it away. Just install the firmware without cutting off the power while updating - or even - without cutting off the power ever when you are not just willing to get into u-boot.

Thanks again, I'll try the tftp thing and get back to you later

@tmomas
Could you please remove the "done" flag on this forum topic? Because the solution is for sure not "throw working hardware away"! And it should never be on working hardware! We live in a non-endless world! Dont waste the world!!!

I've tried putting the modem into Recovery by powering it off then holding the reset button turning it on and holding the reset button for about 20 seconds. I tried

• tftp 192.168.1.1 then mode binary finally putxyz.img
  All I get is 'Transfer timed out'
  Tried pinging it > no luck
  Any suggestions?
  Thx

Hi, finally was a problem with the firmware file that i was using. (i dont know why)
I tried with an older one from a .de mirror repository and it worked doing it using tftp in ip 192.168.0.1 (default ip for this router is 192.168.5.1).

Maybe IP is 192.168.0.1

You are right and a life saver! THANK YOU!

Thank you all. The modem is back on OpenWRT 18.06.0!
Persistence is useful (wink-wink Douglas Adams)
This is now solved!!!
Thanks again!
