Top reply?  Well, anyway I bought a refurbished WNDR3800 from amazon
$40.00 to run cerowrt.  I was hoping to get a compatible model but it
turns out I got a version with model change to WNDR3800-1CHNAS which
cause the firmware upload to fail gracefully.    I found out about
this at openwrt.org, see

The above referenced thread refers to an openwrt developer (zloop) who
says he built a version with a different model string WNDR3800CH.
See https://forum.openwrt.org/viewtopic.php?id=51025

"according to GPL fw sources the router is called "WNDR3800CH" (MODEL_NAME)

so adding a line

Makefile:$(eval $(call

and modify the WNDR3800CH model to the Multiprofile line

$(eval $(call MultiProfile,WNDR3700,WNDR3700V1 WNDR3700V2 WNDR3800

should create an image that can be flashed from factory firmware

PS: it's all untested - no guarantee it will work

feel free to test and send to the mailing list

I'm going to try patching the image header to have the model name
"WNDR3800CH" and see if it will load.

It would be a good idea for the developers who understand the above to
add this model to the makefiles so it also gets built.  I bet a lot of
WNDR3800-1CHNAS series routers are out in the wild and if someone
picks one up to run wrt or cerowrt they will be stymied.
