[OpenWrt-Devel] [BUG] NAND sysupgrade broke ubifs on Netgear WNDR3700v4/4300.

[Paul Blazejowski]

John,

Yes i use the reset with pin and from there i tftp the original firmware
from netgear after that i go to the gui and upload the open-wrt image
because the router will not accept the wndr3700v4 image (there's a
cosmetic fix for that, i created a patch that someone from the forums
has sent months ago to this list but it was never accepted...)
https://dev.openwrt.org/ticket/16840

With that patch tftp'ing the
openwrt-ar71xx-nand-wndr3700v4-ubi-factory.img works without need to
flash the original firmware.

If there's another method that can be used to flash the image(s) please
let me know i would want to try any alternative ways of flashing and
could learn a thing or two in the process as well ;-)

Thank you,
-paul
