Flashing instructions for the E1200 v1

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!

  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 E1200 Trailed Initial Flash Build
  6. Wait 5 minutes to assure flash integrity.
  7. Power cycle by unplugging the E1200 for 5 seconds.
  8. Plug the E1200 back in and wait about 2 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.
  • Due to this unit only having a 4MB flash, you can only use nv64k builds that fit a 4MB flash footprint, using any bigger builds to upgrade with can either fail or worse, brick your unit. You been warned!

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 existing 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 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!
