Manually updating router firmware over ethernet cable - CMD/TFTP2
Hey! I'm at my wits end here so I hope you folks can help me. I was activating my new router with the Nighthawk mobile app - a stupid move, I now realize - when the firmware update was interrupted b...

You appear to be a candidate for the TFTP recovery scheme. See, for

What kind of "responses", when you do what? As usual, showing actual
actions (commands) with their actual results (error messages, LED
indicators, ...) can be more helpful than vague descriptions or
interpretations. Especially when using a command-line program,
copy+paste is your friend.> [...] Trying to use TFTP within Window's cmd leads to "can't read from

file on your Desktop, then you need to point the TFTP program at your
Desktop folder (directory).On Windows, I'd expect your Command Prompt shell program to start up
in your (user-specific) home directory, perhaps something like
"C:\Users\fred" (for a user named "fred"). By default, the Command
Prompt program displays this directory path in its command prompt string
("C:\Users\fred>").
Your Desktop folder would then be "C:\Users\fred\Desktop". To get
there:cd Desktop
I'd expect the command prompt string to change accordingly.
After you've done that, the following command should show you your
firmware image file:dir *.img
If so, then the TFTP program (with the command which I'm guessing
that you were using) should find the file.And, if you've set the computer's (Ethernet interface's) IP address
properly (not ".1"), then you might have more success. Or, at least, a
different error message.> [...] Sadly, I don't think returning the router is an option.
It got you off the phone. I'm sure that that was considered a
success.
