I know this is an old thread but I'm running into the same problem. I've been using DD-WRT, Tomato, and OpenWrt since the original WRT54G came out. I've bricked some routers but usually I could recover them using TFTP. But I'm stuck on this one.
I have my laptop connected via a USB gigabit adapter to a basic 8-port gigabit switch which is connected to 'port 4' (nearest to the WAN port) on the router. I've added a route to 192.168.11.1. I've tried TFTP putting (using Windows 10's tftp client) wzrhpg300nh2-pro-r30356.enc 10-20 seconds after power on to try to find the TFTP window.
I actually created a simple batch file to make sure the timing was as good as possible. I tried it at 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, and 20 seconds after boot. I tried all of those with the uboot MAC address 02-AA-BB-CC-DD-1A, and also with the MAC (SSID) address printed on the router 4C-E6-76-3F-2F-10.
I've also tried countless times using other tftp clients (tftp2.exe, Pumpkin, or tftpd64. Also, using the 'user fiendly' firmware `wzrhpg300nh-176`.
Anyone have any ideas? I'm guessing my only option might be to hook up to its serial port.
Here is the batch script I used:
Code:
@ECHO OFF
REM Power-on to TFTP window delay
SET delay=10
REM Adapter # from `route print`
SET adapter=12
REM Uboot MAC address
SET routerMAC=02-AA-BB-CC-DD-1A
REM sticker MAC address
REM SET routerMAC=4C-E6-76-3F-2F-10

r45000 bricked my buffalo_wzr-hp-g300nh.
Luckily references below helped me out.
"Now quickly plug the power cord back to the router." - I personally needed to do this task many times before I was able to successfully send original firmware to router via tftp.
