Nighthawk 8500 bricked after update

hello community, I own a nighthawk r8500, I downloaded the latest firmware update off the website and uploaded the firmware via Ethernet, router login, walked away for about 15 minutes and came back to the router with the amber light on solid, will reboot every couple of seconds, I’ve did quite a bit of searching on other threads and tried the tftp2.exe, which seemed to have worked but after about 45 minutes it goes back to the solid amber light, I also tried the windows tftp, I have windows 7, and it seems it isn’t able to locate the file while trying to put it, help is much appreciated!

You may want to contact support if you are unable to recover the unit via tftp

   "seems"?  Actual command?  Actual error message?  As usual, showing
actual actions with their actual results (error messages, LED
indicators, ...) can be more helpful than vague descriptions or
interpretations. Copy+paste is your friend.

 

   Which "the file"?  Where is the file?  What is the current directory?

 

      dir
      echo %cd%

 

   If the file is not in your current directory, then you can either move
the file, change your current directory, or else specify a proper path
to the file.

I’ll take screenshots when I get home of my process, I currently have the file in a folder in the desktop. To be honest I’m not to sure how to change my directory or locate it.

   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

 

   To get to a sub-folder named, say, "Firmware":

 

      cd Firmware

 

   Then a command like the following should work (or, at least, not
complain about not finding the specified file):

 

      tftp -i 192.168.1.1 R8500-V1.0.2.130_1.0.99.chk

 

   Alternatively, starting in "C:\Users\fred", specify a path to the
file (instead of only its leaf name) in your TFTP command.  For example:

 

      tftp -i 192.168.1.1 Desktop\Firmware\R8500-V1.0.2.130_1.0.99.chk

 

   A Web search for terms like, say:

 

      windows command prompt directory

 

should find any number of elementary guides (some better than others, no
doubt).  There are many details which may or may not affect you, too,
such as using quotation marks to cope with space characters in
file/directory names.  Research as needed.

I only receive communication from the router for a couple seconds then it times out and it’s usually when it’s powering on.
