Need Testing:
- WPS button

Install via Web UI:
- Attach to a LAN port on the router.
- Connect to the Linksys Smart WiFi Page (default 192.168.1.1) and login
- Select the connectivity tab on the left
- In the manual update box on the right
- Select browse, and browse to
  openwrt-ipq40xx-linksys_ea6350v3-squashfs-factory.bin
- Click update.
- Read and accept the warning
- The router LED will start blinking. When the router LED goes solid, you
  can now navigate to 192.168.1.1 to your new OpenWrt installation.

Sysupgrade:
- Flash the sysupgrade image as usual. Please: try to do a reset everytime
  you can (doing it with LuCI is easy and can be done in the same step).

Recovery (Automatic):
- If the device fails to boot after install or upgrade, whilst the unit is
  turned on:
1 - Wait 15 seconds
2 - Switch Off and Wait 10 seconds
3 - Switch on
4 - Repeat steps 1 to 3, 3 times then go to 5.
5 - U-boot will have now erased the failed update and switched back to the
    last working firmware - you should be able to access your router on
    LAN.

Recovery (Manual):
- The steps for manual recovery are the same as the generic u-boot tftp
  client method.

Back To Stock:
- Use the generic recovery using the tftp client method to flash the
  "civic.img". Also you can strip-and-pad the original image and use
  the generic "mtd" method by flashing over the "kernel" partition.
* Just be careful to flash in the partition that the device is currently
  booted.
