Installation

NOTE: During configuration or flashing a device, the only cables that should be attached to the device are the network cable to your computer and the power cable.
Warning: This unit MUST use K2.6 firmware.
Make sure you use a firmware with wrt610nv2 in the filename like the one below.

ftp://dd-wrt.com/others/eko/V24-K26/svn13575/dd-wrt.v24-13575_NEWD-2_K2.6_mini_wrt610nv2.bin

a. Flash firmware through the Linksys WebGUI.

b. After a couple minutes you should see an "Update Completed Succesfully" Screen.

c. Wait...at least three minutes after that just to be safe.

d. Do a power cycle of the router. (Unplug the cord, count to 10 and plug it back in.)

e. Wait for the lights to return to normal, usually about 2 minutes.

f. Do a HARD reset. Wait. Check for the password page and login to change the password.

g. After you have DD-WRT on the router then you can flash a different firmware from this folder through the DD-WRT WebGUI.

ftp://dd-wrt.com/others/eko/V24-K26/svn13575/

Make sure that you do not flash any build to your router that has the name of a different model router at the end of the filename.

Recovery (Unbricking)

A simple way to recover a bricked device is:

  1. unplug all ethernet ports (Important!)
  2. unplug power
  3. plug power in
  4. wait 2-2.5 seconds
  5. press the reset button and keep it pressed for 5 seconds, then release it
  6. reconnect ethernet (DHCP shoud give IP address to computer)
  7. point your browser at 192.168.1.1. You should see a "Management Firmware update" screen where you can flash the original (Linksys) firmware.

NVRAM Erase breaks Management Mode

Many people have difficulties getting the 610nv2 into management mode using the technique above. It appears that after the nvram is erased (via a 30-30-30 reset for example) the regular "press reset after startup" technique no longer works. Alternatives are to recover via serial console, or to short two particular pins on the flash chip (see http://www.dd-wrt.com/phpBB2/viewtopic.php?p=387245#387245) during startup. Sadly tftp is not an viable option (it will appear to work if your firmware file is under 3.8MB, but the upload will not be flashed).
