Archer A7 AC1750 - US version, V5.8

I tried to upgrade the firmware on my brand new wireless router to the latest firmware, but after update for some reason when a device would connect, dns resolution would fail.  So I tried to downgrade to previous firmware, and the firmware update process seemed to complete.  But when I tried to access the router via hardwire, i couldn't access it.  And the lights on the front of the router only has the power button lit up.

I tried to use the tftp recover to the old firmware, but the router still does not operate correctly.

I have confirmed via tftp logs that the file transfer of the firmware was successful.  But the router doesn't update itself (expecting power light to flash after file transfer, but it doesn't):

Any help or is this router completely bricked?
