[Cerowrt-devel] WNDR3800CH varient doesn't load WNDR3800 firmware

[Sam Chessman <sam.chessman@gmail.com>]

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
https://forum.openwrt.org/viewtopic.php?id=49390

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
SingleProfile,Netgear,64kraw,WNDR3800CH,wndr3800ch,WNDR3700,ttyS0,115200,$$(wndr3700v2_mtdlayout),0x33373031,WNDR3800CH,"",-H
29763654+16+128))

and modify the WNDR3800CH model to the Multiprofile line

$(eval $(call MultiProfile,WNDR3700,WNDR3700V1 WNDR3700V2 WNDR3800
WNDR3800CH WNDRMAC WNDRMACV2))

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.
