tftp/reflash firmware

The basic procedure of using a tftp client to upload a new firmware to your router:

  1. unplug the power to your router
  2. start your tftp client
  3. give it the router's address (usually 192.168.1.1)
  4. set mode to octet/binary
  5. tell the client to resend the file, until it succeeds.
  6. put the file
  7. plug your router, while having the tftp client running and constantly probing for a connection
  8. the tftp client will receive an ack from the bootloader and starts sending the firmware

Please be patient, the reflashing occurs AFTER the firmware has been transferred. DO NOT unplug the router, it will automatically reboot into the new firmware.

  • Linux tftp steps:
    bash-prompt$ tftp 192.168.1.1
    tftp> binary
    tftp> rexmt 1
    tftp> timeout 60
    tftp> trace
    Packet tracing on.
    tftp> put openwrt-xxx-x.x-xxx.bin
