Nighthawk AC 1900 WiFi Cable Modem Router
I have an AC1900 R6900V2 that has become bricked during an update R6900v2-V1.2.0.36_1.0.1.
I cannot do a factory reset Depending on how I Start it, Method 1 Power On) I get an orange power light and an orange light for the port I am hardwired to. No other lights.
Method 2 Press Reset and Power On) I get and orange then Flashing White with no other lights including the Port that my laptop is connected to.
What I have tried: I used the Netgear Instructions for a manual install of the update using two different versions. I pinged 192.168.1.1 before starting and the router returns the ping as successful 4 of 4 packets 100%. I tried connecting to 192.168.1.1 via browser but cannot connect.
Update results:
1) Manual Update using Win 10 tfpt put command for R6900v2-V1.2.0.36_1.0.1 Failed, Command prompt says transfer successful but no change on the router
2) Manual update using Win 10 tfpt put command for R6900v2-V1.2.0.24_1.0.1 which is the last version it was running on. Failed, Command prompt says transfer successful but no change on the router.
Am I missing something or is this unit unrecoverable?

Hard to tell with incomplete details of what you did. No full "printout" from your TFTP session, for example.
TFTP is not the easiest thing to get right.
Netgear's advice:
How to upload firmware to a NETGEAR router using Windows TFTP | Answer | NETGEAR Support
is OK as far as it goes.
You might get clearer information if you ran a search to find a video that takes you through the process.
I followed Netgears instructions to the letter using Windows 10 TFPT as I mentioned above using The latest version and Trying the version before that.
As I mentioned, I can put the router in two different states:
1) flashing white power light and no port light where the PC is plugged in 1,2,3, or 4. This is acheived by Doing a Hard Reset, and the transfer fails
2) Orange power and orange port where the pc is plugged in 1,2,3, or 4 and transfer fails.
I followed the Netgear instruction to the letter AND I have the correct firmware
Ethernet settings:
192.168.1.10
255.255.255.0
192.168.1.1
I also tried using TFTP2 program with the same setting and set it to 3 tries and all attempts timed out.

What is the actual TFTP command which you're using?
