While I was out, I noticed that I was unable to reach smart devices via my mobile device. When I got home to reboot my modem and router, I noticed my Archer AX6000 has the status light cycling/throbbing blue.

I reset my modem and my router, but the router still cycled blue. I tried to factory reset (repeatedly) both via TP Link instructions & 30-30-30. I've reconnected the devices, etc... but no matter what I did, the router would  flash red, green, and then promptly begins cycling/throbbing blue light mode  (which according to the Tether app, indicates "The system is starting up or the router is being reset.") and then stays there, stuck. 
 

I've tried to scour this forum, Reddit, and Google, but was unable to find any solution beyond 'factory rest' - which is the point of the process the device is stuck in. 
 

Has anyone had a similar experience or can offer a potential solution outside of 'factory reset' which I've tried repeatedly.
