Factory reset button is not functioning

[joshhb]

I'm having an issue with my RBR50 Orbi router. I'm not sure if the router is bricked at this point, neither the Ethernet or Internet ports are responding so I can not trying and manually update the firmware. I've tried the 30-30-30 reset to no avail as the power LED will only remain a constant green (not changing to amber whatsoever). I've tried various power supplies which are all 12V - 2.5A and of Netgear varitity. I'm well aware that all my ethernet cords are in good condition and working fine. If anyone has found a fix for this please let me know, thank you.

Need to press the reset button for 30 seconds then release, then it send to PUT the command and upload the FW. 
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.
