Flashing instructions for the E2500

After using the trailed build file for the initial flash (yes the file with the router name in it) 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 30/30/30 reset on router
  4. Connect 1 Lan cable to pc doing the flash.
  5. Log into Linkysys Web Interface Firmware Upgrade page at and flash the firmware E2500 Trailed Initial Flash Build
  6. Wait 5 minutes to assure flash integrity.
  7. Power cycle by unplugging E2500 for 10 seconds.
  8. Plug E2500 back in and wait about 3 minutes until it finishes booting.
  9. Do a 30/30/30 reset on router.
  10. Wait 3 minutes and log into web interface.
  11. You are done.
  • 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.

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, also avoid the test builds within the E2500 forum thread and the builds linked in the dd-wrt router database as they are known to cause a reboot loop. For the safest results, use builds that are linked within this wiki.

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!
