Flashing instructions for the E1550

After using the trailed build for the initial flash (the file containing the router name) only use nv60k builds to upgrade with or you will brick your unit!

  1. Read the Peacock Announcement carefully.
  2. Disconnect all cables and wireless clients.
  3. Do a reset
  4. Connect only a LAN cable to the PC doing the flash.
  5. Log into Linksys Web Interface Firmware Upgrade page
  1. Wait 5 minutes to assure flash integrity.
  2. Power cycle by unplugging E1550 for 10 seconds.
  3. Plug the E1550 back in and wait about 2 minutes until it finishes booting.
  4. Do a reset. Another power cycle after the reset might be required if the LAN is not working.
  5. Wait 3 minutes and log into web interface.

  • After the initial flash - should you want to flash to a build with more features you can use a k2.6 nv60k Big or mega build or any of the other build flavors that are of your liking for features.
  • The nv60k Big build provides USB support (also NTFS, unlike mega), unlike the initial trailed mini build.
  • K3X builds should work (it has a trailed build), but have had very limited reports of usage

Build information

As noted in bold at the beginning of the flashing instructions, only use builds with nv60k 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 nv60k 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 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!

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 @
