De-bricking and TFTP Info
It has been asked about on how to de-brick this unit in the case that a flash goes wrong or how you can switch back and forth between Buffalo dd-wrt builds and community dd-wrt builds.
This method is if you are using Windows XP OS. I also always use a 10/100 or Gigabit hardware switch in-between the router and the PC, this way - Windows doesn't have to wait for the router switch to initialize, which can make you loose your TFTP timing window.
Power the router off for now. Make sure you are wired into the switch LAN ports and use the LAN ports only, not the WAN port.
1) Set a static ip on the pc of 192.168.11.2 / 255.255.255.0 Gateway: 192.168.11.1
2) Open a command prompt and type this: arp -s 192.168.11.1 02-aa-bb-cc-dd-20 [enter]
3) After entering the static arp have the command line ready with this command (and you'll have to be in the dir where the firmware image is at or it won't work): tftp -i 192.168.11.1 put wzrhpag300h-pro-v24sp2-17798-alpha.enc
4) Do not enter the TFTP command, just having it waiting for now, with the power to the router still off, Plug in the power for the router and count to 10 seconds or use a stopwatch, then enter the TFTP command that you should have waiting in the command prompt. This is an important timing step for TFTP to work
5) You'll know if it transferred by the command prompt telling you so, give it about 5-6 minutes after the transfer, if the flash was successful, it'll reset/program itself in this time. Once it is complete the Red Diag LED should go off and then you can access it at 192.168.11.1
Please note that the above method is performed using the Buffalo Branded DD-WRT .enc builds, to use a community DD-WRT build you will need to browse the FTP and choose which build number you want to use and get the file with the naming format of 'buffalo_to_ddwrt_webflash-MULTI.bin' and substitute the above .enc file. Please also note that if you use the community dd-wrt build to flash with, the IP access for webgui using community builds will be @ 192.168.1.1 instead of 192.168.11.1 So once the red diag led goes off you will need to use 192.168.1.1 for webgui access but all the other steps stay the same.
Also i am noticing alot of people trying to TFTP to 192.168.1.1 - this will not work, no place in this guide does it say TFTP to 192.168.1.1 - The IP for buffalo's bootloader is 192.168.11.1 so you must follow the steps above carefully in order for this to work and a hardware switch, 10/100 or gigabit is very important as well.
