Is this a NG retail system or did you get it from a ISP?
IF this is ISP FW which some ISP do handle, then you'll need to contact the ISP about FW updates.
You can try using TFTP and see if NG stock FW will load...

I had a problem on a Windows 10 PC where this didn't work to use TFTP, so I switched to a Windows 7 PC and the TFTP worked.

If that failed, I would return the Orbi system back to the ISP.
You'll need to find a different system then. Something Retail and not ISP developed.

Netgear routers have pins for a serial (RS232) interface on the internal circuit board. A USB to serial converter is under $20. But then you have to learn how to access the underlying U-boot and Linux systems from a command window and figure out what to change. Could be 100's of hours of learning curve. Meanwhile.... no internet.
A clever person discovered how to change an RBR50 into an RBS50 by using telnet to alter one parameter in the ROM. Since that hack was discovered several years ago, it has not been repeated with any other Orbi model. (Lack of interest? or... too hard? no one knows)
Verizon did a similar thing with the original RBR50 systems. Sold them to customers with promises of support, and then never updated the firmware. Not once.
