I have been super busy and have only just managed to get around to looking at this. The long short though, no real progress.
I found some useful output from a working WNR2000v2 here (http://www.linksysinfo.org/index.php?threads/tomato-nd-usb-mod-with-kernel-2-6-tomato-rt.31335/page-17#post-154650). This shows the offset for the board_data partition at:
Code:
0x003e0000-0x003f0000 : "board_data"
So, based on Dark_Shadow's attempts in his debrick for a WNDR3300, I tried to flash LOMs BIN file above to the offset listed above by using:
This resulted in an I/O error, but must have done something as it over wrote the routers IP address. As such this needed to be reset using the 'ifconfig' command. I then tried to flash the stock firmware, wait for the programming, and then reboot, but all seem to go back to the same as before. Have tried powering down and up as well.
I have tried a few variations such as using the -size parameter (-size=0x10000, which was calculated by taking the beginning Hex memory position for the board_data partition from the end Hex position) of the flash command, but no dice.
Sample output below:

Looks like Dark_Shadow's ran into similar issues, but seemed to get around this by flashing a cut version of a whole flash backup (removing the initial CFE section - thanks the EKO and LOM). See page 6 (https://www.dd-wrt.com/phpBB2/viewtopic.php?t=72874&postdays=0&postorder=asc&start=75).
LOM, you don't happen to have a whole flash backup of the WVN2000v2 do you?
Otherwise, does anyone want to buy a partially used WNR2000v2 ?
Many thanks for all the help with this, but I haven't been able to fix it. As such if anyone wants it to play with (UK) please let me know, otherwise I gonning to junk it.
