ASUS WL-500GP v2: flash firmware using CFE

I had a bricked router Asus WL500GP v2, luckily the CFE bootloader was still reachable through serial port. After setup a TFTP server and downloaded the appropriate upgraded firmware from OpenWrt, the CFE command was:

flash -noheader flash1.trx


  • flash1.trx is the destination flash (and not flash0.trx as I saw in some tutorials)
  • is the TFTP server IP
  • openwrt.trx is the firmware image
  • -no header is that option to override header verification
