Flashing
Warnings
- The e4200 is very sensitive to the nvram size. The only safe nvram size identified for this router is an nvram size of 60kB. Recovery from a firmware with the wrong nvram size requires use of a jtag cable to erase the nvram.1
Flashing Process
- Perform these steps when flashing from the stock linksys GUI:
- Disconnect all cables and wireless clients.
- Perform a 30/30/30 reset on the device.
- Flash the latest E4200 specific mini build (dd-wrt.v24-<build number>_NEWD-2_K2.6_mini-e4200.bin) to the router.
- Wait approximately 5 minutes for the flashing process to complete.
- Perform a 30/30/30 after the device has successfully updated.
- Flash to larger build of your choosing (Mega, Big, std_usb_nas, OpenVPN, VoIP.)
- WARNING Only flash -nv60k builds, flashing anything else to the router will brick it as noted above (dd-wrt.v24-<build number>_NEWD-2_K2.6_<build type>-nv60k.bin)
- If flashing to another build always perform a 30/30/30 before and after flashing.
