one user reported on IRC having a WNDR3800 with FW 1.0.0.51CH , a branded device it seems
He could not flash the factory fw of WNDR3800
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
