Need to press the reset button for 30 seconds then release, then it send to PUT the command and upload the FW. 
Make sure you enable tftp: https://www.thewindowsclub.com/enable-tftp-windows-10
Video walk through using a tftp client. Use the built in one for windows 10 though. the video is more of an example of how its done:

Do you have the WAN port connected? If so remove the WAN port, then factory reset again by pressing button for 30 seconds and try again

There is no WAN port connected, and the laptop is connected to port 1 next to WAN port

The RBR750 should load firmware the same way as the RBR50.

 

I do this very seldom (because I have not bricked my router in some time now).  I find the process a bit frustrating, what with having to disconnect all the other cables, set the PC up with a static IP address, etc.

 

The last time I did this, the first five attempts were failures.  I was about to toss the router into the trash and thought, "what else do I have to do right now?"  Why not do this some more.  The sixth time, it took.

 

What I observed is that there appears to be a window of time when the router boot process looks for a TFTP connection to upload firmware.  After that, it proceeds to load the saved firmware image and quits accepting a TFTP connection. Try to upload too soon, and it fails.  Wait too long, and it fails.  Hit the "sweet spot", and it works.  i (literally) would get the TFTP64 program (Windows) set up to transfer, press the power button on the router and count (one potato, two potato) and click the Send button.  Then, (one, two three - button).

 

My impression is that nmrpflash is a version of TFTP that is built to handle the timing issue internally. (Maybe it tries over and over until something takes). https://github.com/jclehner/nmrpflash
