Flashing instruction

TFTP flash

The latest DD-WRT build has a new, easy, and safe way to flash a WHR-G300N router. To do this, just Tftp_flash the new image to 192.168.11.1 in the 1st three seconds of booting when the router is in recovery mode.

Web flash

From now on there is preflash image in the whr-g300n folder that makes the serial access unnecessary for the initial flash to DD-WRT.

  • Flash DD-WRT-WHR-G300N-preflash.enc via web-if
  • The device will reboot
  • Then flash the firmware.bin image via web-if, too, to finish the way to dd-wrt.
  • After the automatic reboot DD-WRT will be accessible at 192.168.1.1

Serial flash

It's also possible to flash this device with serial interface, this is handy also for troubleshooting.

  • Solder pins to the 4 pin serial header near the wifi part:

  • Prepare TFTP server (e.g. the one from the dl area).
  • Download the latest DD-WRT WHR-G300N build to the root folder of the tftp and rename it to firmware.bin
  • Set the IP address of your PC or the device which runs the tftp server to 192.168.11.2/24
  • Set your consolte programm to 57600,8,n,1
  • The boot timeout is 3 sec so you will have to be very fast with the following step.
  • Power-on then following message will be displayed at the console.
---------------------
Please choose the operation:
1: Load system code to SDRAM via TFTP.
2: Load system code then write to Flash via TFTP.
3: Boot system code via Flash (default).
4: Entr boot command line interface.
9: Load Boot Loader code then write to Flash via TFTP.
---------------------
  • Select [4] and put in this command
run ut_fw

Then the firmware.bin will be loaded from the tftp server and automaticly flashed.

  • After the automatic reboot DD-WRT will be accessible at 192.168.1.1
