Flashing instructions for the E900

After using the trailed build file for the initial flash (yes 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 of the other Linksys E-Series units that use nv60k builds, this one uses nv64k builds!

See: Where do I download firmware? for build links.

  1. Read the Peacock Announcement carefully.
  2. Disconnect all cables and wireless clients.
  3. Hard or GUI reset the router
  4. Connect via LAN cable to the PC doing the flash.
  5. Log into Linksys Web Interface "Firmware Upgrade" page (default:
  6. Flash a trailed build (with 'E900' in the file name) from the broadcom_K26 folder.
  7. Wait 5 minutes to assure flash integrity.
  8. Power cycle by unplugging the E900 for 10 seconds.
  9. Plug the E900 back in and wait about 2 minutes until it finishes booting.
  10. Reset again. Another power cycle may be required after this, as noted by some forum users.
  11. Wait 3 minutes and log into web interface.
  12. You are done.
  • After the initial flash - should you want to flash to a build with more features you can use a k2.6 nv64k BIG or mega build or any of the other build flavors that are of your liking for features. K3X builds will work on this, provided they are smaller than 8 000 000 bytes in size and nv64.

Build information

As noted in bold at the beginning of the flashing instructions, only use builds with nv64k in the name for upgrading - otherwise follow the initial flash instructions above if you are going from stock to dd-wrt, any other builds for upgrading an exsisting dd-wrt install without nv64k in the name will brick your router! This unit was supported with build 18946 or greater, this means you cannot use a build with a number lesser than 18946. For the safest results, use builds that are linked within this wiki as they have most likely been forum tested with ok reported results.

To find the latest builds, you can browse the DD-WRT file server and look for the latest build number then look for broadcom_K26 folder, in there is the appropriate for your unit. Be aware that these are beta test builds and should be used with caution!

See: Where do I download firmware? for build links.

Reverting to stock firmware

It has been asked about: "how do i revert back to stock firmware?" and the answer is 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 @
