Model: Archer A7  
Hardware Version: V5
Firmware Version:

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):

Connection received from 192.168.0.86 on port 2509 [03/03 12:35:39.580]
Read request for file <ArcherC7v5_tp_recovery.bin>. Mode octet [03/03 12:35:39.581]
OACK: <timeout=5,blksize=1468,> [03/03 12:35:39.588]
Using local port 65483 [03/03 12:35:39.588]
<ArcherC7v5_tp_recovery.bin>: sent 10606 blks, 15568476 bytes in 2 s. 0 blk resent [03/03 12:35:41.707]

 

Any help or is this router completely bricked?

Really the only thing you can do if a firmware upgrade/downgrade has failed and bricked the unit is the TFTP manual recovery.  If that also fails then a replacement may be in order.  I see you are registered from the US.  Here we just need to confirm that the Firmware you were attempting to install were from the US site and not another region.  If that is the case then please register here and let me know so I can approve the RMA.
