I've found a way to permanently (?) alter the board ID to enable the flashing of stock Netgear (non-Charter) firmware by activating telnet via a tool called telnetenable2, connecting via telnet, changing the board id by running a few commands, and then uploading the standard firmware.

1) download telnetenable2: http://www.mediafire.com/file/tcen54n6k66yu58/telnetenable2.zip/file

2) run powershell or cmd (win + r)

3) provide it mac id from bottom of router as instructed along with 192.168.1.1 and default port 23 - the magic packet will be sent activating telnet

4) connect via telnet by running cmd/powershell "telnet"; proceed to connect to default telnet port 23 on 192.168.1.1

5) submit command "burnboardid U12H240T00_NETGEAR"

6) submit command "nvram set board_id=U12H240T00_NETGEAR"

7) flash default firmware

I'm in the process of downloading and flashing the the proepr ddwrt initial flash for the non CH edition.

The wiki needs to be edited. The md5 in the wiki is from the old desipro.de link. I'll let @jwh7 know. Thanks for letting us know!

you might need to flash the smaller file initially, 13MB file, then upgrade to latest. attached to this post. i've bought many used R6300v2CH and thats the only file that would flash initially.

Kong recommended not to change board ID, i would stick to that.

latest will not flash from stock on charter version

please use the sub 13MB file, it's the only one that works as an initial flash from stock.

FWIW I converted my charter to a regular r6300v2 many months ago as explained in this thread. It has been super stable and have no regrets but YMMV.

I've managed to brick mine (flashing power light) and nothing I seem to do will restore it. Tried flashing every firmware file (including CH) via TFTP and nmrpflash. I'm guessing altering my board id and the recovery process may be conflicting. Ping is successfull with ttl=100.
