Dear DD-WRT,
I have been using DD-WRT with a lot of pleasure the last couple of years, and as I came home from China after half a year I thought it was a good moment yesterday to upgrade my router(WZR-HP-G300NH) with the latest firmware.
At first I tried the official DD-WRT upgrade for the WZR-HP-G300NH but the old DD-WRT install didn't seem to accept that, so than I went to the DD-WRT website to get the latest unofficial update. Unfortunately (probably because I didn't sleep for 40 hours because of my travel back to Holland) I downloaded the WHR-HP-G300NH firmware and it updated without any notice and even said "succesful", but as I can understand now it bricked the router.
The router is now stuck at the red DIAG led and reboots every 15 seconds, I did 30/30/30 reset, I tried every TFTP method(Linux, Windows 7, Windows XP, with or without switch in between and with multiple router firmwares from the buffalo website) but it never seems to accept the files. I always see notices that it tries to push it to the router but I never saw the router accept anything during boot-up so after a day of trial and error I'm still stuck with a bricked router and I don't see any solution.
What should I pay attention to for a final try or is there any other normal solution next too TFTP? I read some similar stories but I never get it working :(
Hope you can help me, before I need to buy a new router... And what would you suggest if I did(120mbit internet so it needs to be quick )?
Like I didn't try that The problem is that it didn't work...
Anyone have other good options, I have a Netgear WNDR3700 in the mean time, but I would also like to get my WZR-HP-G300N back to work
from my oppinion the guide is wrong.
first you need to assign a mac address for 192.168.11.1 with arp. but the mac address shown in the guide is wrong. you must use 02:AA:BB:CC:DD:1A
so arp -s 192.168.11.1 02-AA-BB-CC-DD-1A
then use tftp -i 192.168.11.1 put ....bin
the bin file must be the factory to dd-wrt flash image and not the dd-wrt webflash image.
ah and by the way. the tftp server will listen for just 4 seconds, but not right up after you plugin the power. no you usually have to wait up to 10 seconds until you can hit enter with tftp. just all about timing _________________ "So you tried to use the computer and it started smoking?

I just happened to pick up a WZR-HP-G300H to replace my old WRT54G (w/dd-wrt). It shipped with V24-SP2, I wanted to checked out the Buffalo firmware. I flashed like normal and waited the some 300s, now the diag light continues to flash.
That worked! I flashed it using win7x64 with windows tftp using the buffalo version wzrhpg300nh-176.
After flashing dhcp wasn't working. Set my nic to a static 192.168.11.25/255.255.255.0. After trying to figure out why I couldn't connect to 192.168.11.1, I fired up WireShark and watched for traffic from any .11.x IPs, the router showed up as 192.168.11.100.
The web interface loaded right up with root/no password.

yes. this can be used for tftp recovery as well as for flashing dd-wrt out from the original buffalo firmware _________________ "So you tried to use the computer and it started smoking? Sounds like a Mac to me.." - Louis Rossmann https://www.youtube.com/watch?v=eL_5YDRWqGE&t=60s
Thanks a lot BrainSlayer, it worked perfectly Feel a bit stupid that I didn't find this solution before I bought a new router but at least it's still useable now so that I can put it as an extra switch and wireless access point
Hope this solution can be added to the documentation/wiki's so that everyone facing compareable problems can fix it before buying a new router
