[edit] Flashing Instructions

After using the initial flash trailed build (the file with the router name in it), only use nv64k builds to upgrade with or you will brick your unit. Don't confuse this unit with some other Linksys E-Series units that use nv60k builds!

[edit] Initial Flash

  1. Read the Firmware_FAQ and Peacock Announcement.
  2. Connect a LAN cable to the PC doing the flash, and disconnect other cables and wireless clients
  3. Do a hard reset on router
  4. Log into Linksys Web Interface Firmware Upgrade page
  5. Upload the known good initial flash E1200 (v1) Trailed Build
  6. Wait 5 minutes to assure flash integrity, then power cycle the E1200 (unplug for 10 seconds).
  7. Plug the E1200 back in and wait about 2 minutes until it finishes booting.
  8. Do a hard reset, then wait for it to boot.
  9. Open web interface to set a user and password, then configure as needed.

[edit] Upgrade DD-WRT

  1. To upgrade, use a k2.6 nv64k mini build (_K2.6_mini-nv64k.bin) from the /broadcom_K26 directory.
  2. Research build threads first to avoid bad builds.
  • WARNING: only use nv64k builds that fit a 4MB flash footprint, bigger builds can either fail or brick your unit.
  • Do not try to flash K3X: while a K3X trailed and nv64k build exists, the files are for minimum 8MB flash devices.

[edit] 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.

[edit] Build Information

Support for this model was added with build 18946, so do not use any older builds. To be safe, only use builds that are linked within this wiki, or otherwise read New Build and model-specific forum threads. To find the latest builds, look here in broadcom_K26 folders.

[edit] Reverting to Stock Firmware

Download the stock firmware image from the manufacturer's website, 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
