Flashing Instructions

WARNING: only use nv64k builds to upgrade. Don't confuse this with other Linksys E-Series units use nv60k builds!

  • These instructions were performed with an e1200v2 running FW_E1200_v2.0.07.002_US_20150108.bin
  1. With a wired connection, log into the Linksys Web Interface Firmware Upgrade page.
  2. Do a reset using the stock web interface. Wait a minute.
  3. Flash the initial flash firmware: dd-wrt.v24-19519_NEWD-2_K2.6_mini-e1200v2.bin
  4. Wait 2 minutes for the router to flash and reboot itself.
  5. Wait about another 2 minutes until it finishes booting.
  6. Log into the dd-wrt web interface and set a password
  7. Flash the -nv64k.bin upgrade build then when complete, reset using the GUI
    • Wait 3-4 minutes for the flash to complete, then if isn't accessible, manually power cycle the router

For download links, build information, and more: Where do I download firmware?

Minimum build with the Broadcom krack fixes is 33772. See here for more info.

No LAN ports After Reset

There is a persistent bug with some E-series routers in DD-WRT after a reset, where the LAN-ethernet ports are not bound to anything, and only wireless (WLAN) is working initially.

Fix: access the web interface using wireless and add vlan1 (ethernet ports) back to the bridge.

  • For a step-by-step and more details see here.


Recovering from Management Recovery Mode

Follow the E1500 directions, substituting e1500 for e1200v2 and using the appropriate firmware.


Reverting to Stock Firmware

Download the stock firmware image from the manufacturer's website (link), reset the router back to defaults using a 30-30-30 hard reset, then flash the stock image from within the dd-wrt webgui. After 5 minutes it should finish, you will then need to do another 30-30-30 reset and then access the stock webgui @ 192.168.1.1
