WARNING: Enabling JFFS bricks the router: "That seems to nuke all the way up to 0xFEFFFF in the SPI flash."

  • TheDoc's fix for bricked v3/v4 is here.

Troubleshooting

Device Forum Thread: https://dd-wrt.com/phpBB2/viewtopic.php?t=282831

Bricked Router

Symptoms: all the LEDs are ON, and you can't access to UI

Follow these steps:

  • Switch off the router
  • Download a complete binary-image of firmware
  • Rename the downloaded firmware with the following name: archerc9v1_tp_recovery.bin or "archerc9v2_tp_recovery.bin" if you have a v2 router
  • Serve as TFTP server the renamed firmware on the following IP: 192.168.0.66
  • Switch on the router, holding the RESET button for 2-4 seconds
  • The firmware will be automatically downloaded and installed by the router

Symptoms: after the dd-wrt installation the MACs are changed!

Recovery Mode

The v3 CFE has a built-in Webpage Firmware Recovery mode for bricked routers: see TP-Link article.
