Yes.
I have owned WNDR3700v1, WNDR3700v2 and also WNDR3800, which all are identical (except RAM and flash size). During the 11 years that I published a community build here for the router family (Build for WNDR3700v1/v2 / WNDR3800 (discontinued)) , I had to use both the OpenWrt failsafe and the Netgear TFTP mode several times with all the routers.
