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!

  1. Read the Peacock Announcement carefully.
  2. Disconnect all cables and wireless clients.
  3. Do a hard reset on router
  4. Connect a LAN cable to the PC doing the flash.
  5. Log into Linksys Web Interface Firmware Upgrade page
  6. Upload the known good initial flash E1200 (v1) Trailed Build
  7. Wait 5 minutes to assure flash integrity.
  8. Power cycle by unplugging the E1200 for 5 seconds.
  9. Plug the E1200 back in and wait about 2 minutes until it finishes booting.
  10. Do a 30/30/30 reset on router.
  11. Wait 3 minutes and log into web interface.
  12. You are done.
  • WARNING: only use nv64k builds that fit a 4MB flash footprint, bigger builds can either fail or brick your unit.

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 @
