I have a FIOS G110o gateway from ebay which works perfectly but I am not getting updates from Verizon. The part of the reason I believe is its a frontier gateway router. I tried to apply the update via http://192.168.1.1/#/advanced/fwupgrade after downloading the firmware file from https://www.verizon.com/support/residential/internet/equipment/open-source-software.
As soon as I upload the file it shows busy cursor for couple of seconds and then nothing happens. Please suggest if there are any other possible solutions
