Night hawk AX4 does not show network and red light is blinking

[SirKoogles]

nighthawk router's power light is blinking red. It also doesn't show up on available networks.  User manual says blinking red light means it needs a firmware update, but I can't update the firmware withought being connected to a network.

   You may be a candidate for the TFTP recovery scheme.  See, for
example:

   What, exactly, does "connected to a network" mean to you.

   You need an Internet connection to fetch a firmware kit.  Once you
have the firmware kit, a minimal network connection between computer and
router may be sufficient to use the TFTP recovery scheme.
