OpenWrt Firmware for Archer c6 v3.2

For Developers
218

Anyway, assuming that:

  1. You installed a snapshot image (without LuCI)
  2. You want to revert to stock firmware
  3. Your device does not have an Internet connection
  4. You have a Windows 10 PC
  5. Your OpenWRT Archer C6 v3.2 is turned on, up and running
  6. You can ping and ssh your OpenWrt device at 192.168.1.1

Then execute the following steps to revert to stock firmware:

  1. Download a ZIP with the revert image of the Archer A6/C6 v3 I've made from [here]( a6c6_v3_sysupgrade_factory_revert.bin.zip (Password: a6c6revert)
  2. Unzip the file contents to a folder in your PC (ex: "C:\tmp"). You should get a file named "a6c6_v3_sysupgrade_factory_revert.bin" in this directory
  3. Open a windows command prompt and change the current directory to the folder you unzippped the revert image: cd c:\tmp
  4. Copy the revert image to the device using the Windows scp command:
    C:\tmp>scp a6c6_v3_sysupgrade_factory_revert.bin root@192.168.1.1:/tmp
  5. Open an ssh session to your device:
    ssh root@192.168.1.1
  6. Flash the revert image with the following command (ignore the warnings):
    root@OpenWrt:~# sysupgrade -v -F /tmp/a6c6_v3_sysupgrade_factory_revert.bin
  7. Wait for the flashing process to finish. After the device reboots, you can access the stock firmware at http://192.168.0.1
  8. Using the stock firmware after the revert, it is strongly recommended to flash a new firmware stock image downloaded directly from TP-Link website.
