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!

  • Read the Peacock Announcement carefully.
  • Disconnect all cables and wireless clients.
  • Do a 30/30/30 reset on router
  • Connect 1 Lan cable to pc doing the flash.
  • Log into Linkysys Web Interface Firmware Upgrade page at and flash the firmware E900 Trailed Initial Flash Build
  • Wait 5 minutes to assure flash integrity.
  • Power cycle by unplugging the E900 for 10 seconds.
  • Plug the E900 back in and wait about 2 minutes until it finishes booting.
  • Do a 30/30/30 reset on router. Another power cycle may be required after hard reset as noted by some forum users.
  • Wait 3 minutes and log into web interface.
  • You are done.
