It didn't work. after it finish the router keeps flashing green power light.... reset button doesn't work! how u make it install the firmware and get out of tftp manually? it should be a way to do it.

Removed router board and hooked up a serial 3.3v ttl connection. This allows you to see what is going on and why the update is failing.

The firmware uploads correctly, but the router then checks for hardware ID, which for the erased firmware is now ff ff ff ff etc, it wants to see 29763551+04+32.. no go
error message:
Board HW ID mismatch, it is forbidden to be written to flash!!

With serial 3,3v ttl interface cntl c twice, this gets you into a command line mode, type ? to see the list of commands.... there are a lot of commands.

have
"board_hw_id_set" good set HW ID

board_hw_id_set 29763551+04+32

" board_model_id_set" need this one too

board_model_id_set wrn2000v3

Bingo.. now the firmware will upload and run. Router good to go..

WOW! things are a little different than I expected...

Did a serial probe of a stock out of the box unmodified wrn2000v3 firmware V1.1.1.58 router and
board_hw_id is set to ff ff ff ff
board_model_name is set to ff ff ff ff

There is a command "protect [Enable Disable]" that enables or disables FLASH write protection.

OK bulldog, I will test if I can upgrade an unmodified router with tftp..... try uplaoding a netgear firmware update.

No the update fails with "HW ID on Board mismatch, it is forbidden to be written to flash!"

Looks like its not possible to tftp any firmware to the router without without board_hw_id set and board_model_name set or protect disabled. Serial command line can do that, I am not sure about OpenWrt.

I guess one could have a GUI firmware update that wrote to the 9f3f000 area that would allow tftp updates.

So far to me it looks like serial is required to set up the router to accept and run tftp uploads.

The following is for a new wrn2000v3 router firmware V1.1.1.58 GUI updated through firmware V1.1.7.2. No DD-WRT firmware ever loaded.

The router can be set to tftp mode by holding reset button down, turn power on, it will flash yellow then start flashing green, at this point it is in tftp mode.

Firmware update "img" files can be sent to the router and the transfer looks good.

Now per the Wiki, Peacock, Rooster, off-sight info etc we wait 5 minutes for the router to update.

BUT this router will not update the firmware because it fails an internal check.

Bottom line is I wasted a lot of time trying to get the router to update in the tftp mode.

Now is this a "feature" of this router or a "bug" in the router?

I am going to guess that it is a "bug" in the router and maybe there will be a factory firmware update that will take care of this "Bug".

As pointed out by Mangix use http://www.techinfodepot.info/index.php/Netgear_WNR2000_3.0#Serial_Recovery
to set the parameters and eliminate this "bug" or "feature".

PS The firmware img file must have that it is for hardware 29763551+04+32 and model wnr2000v3 which the factory firmware updates have.
