Picked up a Netgear R6900 for $10 at Goodwill. Wanted to put DD-WRT on it so followed the excellent instructions by @r39o in the following thread:

https://forum.dd-wrt.com/phpBB2/viewtopic.php?p=1042859#1042859

Unfortunately telnetenable was NOT activating telnet (could not open port 23).

I spent the last few days trying to get this procedure to work (on Win 10 Pro and later on Win 7 Ult) with no joy.
My router is an R6900 v1 that I had flashed to firmware R6900-V1.0.1.16_1.0.15.

After having given up, did one more search and found a post in another forum concerning a Charter issued R6300 router, and followed his instructions. Combined with @r39o 's tutorial (and making sure telnet was installed on the PC) the following method worked on the first try.

1.
a. Download nte.exe (I paced it in Windows\system32 for ease of use).
b. Download factory-to-dd-wrt.chk image for R7000 (Kong build would NOT flash!)

2. Hard reset router (button on back).

3. (I used Win 10 Pro for this part)

a. Open Windows PowerShell (Admin)
b. (Making sure to use YOUR routers LAN MAC, LAN IP, password and username) run the following command:

nte mac=MA:CA:DD:RE:SS:XX name=192.168.1.1 password=password user=admin

c. (After nte reports it recieved packet) run the following command:

telnet 192.168.1.1

d. At the # prompt run the following command:

set burnboardid U12H270T00_NETGEAR

e. At the # promt run the following command:

nvram erase && reboot

f. Close Powershell and wait for router to reboot.

4. After router has rebooted, once again hard reset router (button on back).

5.
a. Log in to router with default user and password.
b. Use the GUI to reset router defaults.
c. Use GUI to reboot router.

6. After router has rebooted, Log in to router and flash with your factory-to-dd-wrt.chk

7. After router has rebooted, once again hard reset router (button on back).

8. For good measure I also logged into the DD-WRT GUI and reset defaults and rebooted once more.

9. Set your preferences and be done.

Perhaps this will help some other weary soul trying to accomplish basic things with a near-zero budget.

If I am not mistaken, you have to flash the oldest firmware version on R6900 to get the original telnetenable function to be visible or work.

I had also tried the oldest firmware in the beginning, and when it did not work I flashed it to firmware R6900-V1.0.1.16_1.0.15 thinking maybe telnet was not there in the oldest version (I don't exactly know where telnet ability resides in a router).

My apologies for not having mentioned this in the OP.
