In attempting to install OpenWrt on a Belkin F5D8235-4_v1, I found that it failed to flash through the web interface.
I also failed to install via TFTP from U-Boot. It never requests the file and times out.
I recompiled busybox to include tftp command and can successfully retrieve the file from the router when it is booted up normally. Next, I thought I'd try using Kermit to flash OpenWrt from U-Boot but that functionality was not included in the installed U-Boot version so I recompiled U-Boot and am unable to flash from linux on router presumably because the U-Boot partition is read only.

So, I seem to be pretty well stuck with this and could use some help.

so what firmware is on the router now stock still or it is bricked?

When I got it, it had 1.01.19 at the moment it has firmware 1.01.28, but I can and have (re)flashed 1.01.19, 1.01.24, 1.01.26 and 1.01.28. All versions stock from Belkin.

Maybe this helps you?

That did the trick, thanks! That was lots easier than I was making it. Can't believe I didn't happen upon that information  in any of my google searches. Thanks again.

FYI: I just added installation instructions according the linked LEDE forum posting to https://wiki.openwrt.org/toh/belkin/f5d8235-4
