If you have a WNDR3700 v4, download from here following the same flashing steps: Use the r23503 factory file to get on DD-WRT first, then use the webflash below to be updated to the latest build. If you flash with a factory img file newer than r23503, stock firmware will give a cgi timeout error. V4 units are labeled on the side of the box, in firmware, & under the router as "WNDR3700 v4". K3.X builds do work on this unit but you must first flash K2.6, as there is no mini K3.X build.Įnsure mega builds are less than 7995392 bytes (7808 KB) in size before flashing or you will brick the unit.This is a Broadcom unit with 64k nvram, identical to WNDR4000.

Upgrade Builds: Use nv64k.bin (or trailed) builds. Initial Flash: From the WNDR3700 v3 OEM GUI, flash a k2.6 trailed build (broadcom_K26 folder): V3 units are labeled on the side of the box, in firmware, & under the router as "WNDR3700 v3". Netgear has put a check in later firmware revisions to see if you are not using their firmware and will fail. Note: You must have no later than 1.0.0.12 of the netgear factory firmware in order to flash dd-wrt to this unit. Web Flash BIN (Both) to upgrade dd-wrt: Go to the netgear-wndr3700v2 folder then download the wndr3700v2-webflash.bin file World Wide (WW): Go to the netgear-wndr3700v2 folder then download the wndr3700v2-factory.img file North America (NA): Go to the netgear-wndr3700v2 folder then download the wndr3700v2-factory_NA.img file If you have a WNDR3700 v2, download from here following the same flashing steps: V2 units are labeled on the side of the box, in firmware, & under the router as "WNDR3700 v2". Version 35681 has been confirmed to work by tmittelstaedt on the version 1 Netgear 3700. Then upgrade to the latest version of DD-WRT using the webflash file. Success for the initial DD-WRT build was found using r29059 (a 2016 build). Please note, a smaller sized build will be required for the first flash, as newer ones (2018+) are too large for the factory sized linux partition.

Webflash is from upgrading an existing DD-WRT firmware to a newer build via update firmware option. factory_NA.img is the same except for North American units. Note: factory.img is for worldwide units flashing from NETGEAR firmware to DD-WRT, or recovering from TFTP mode. Installation of DD-WRT is very simple and can be done in a few steps. v5 is not supported and there is no ETA, each of which requires its own firmware build, whether you use stock firmware or DD-WRT. To date there are 5 hardware revisions of this router, v1, v2, v3, v4, and v5.
