XR500-100NAS v2.2.1.10 DumaOS Not Loaded Endless Cycle

[Nighthawk Pro Gaming]

I bought an XR500 the other day (so far, love it - getting ethernet-comparable pings through multiple walls at 60' with MU-MIMO), and I am having trouble getting it to update to the latest firmware. When I first tried to set it up, it was with the smart phone app, and I had some trouble. It started the update during this process, and it seemed to hang. When I connected to the router from a PC to see what was going on, I was greeted with "DumaOS not yet loaded" and the page refreshing every 5-10 seconds or so. I was able to connect to the internet via the default wireless network it was putting out, but couldn't configure anything. I pulled up the following page, and it got DumaOS to load:

But I prefer to have the latest version of any firmware loaded. I gave it another shot today. Updating via the router's built-in tool results in the "DumaOS not loaded" page. So I rolled back to v2.1.0.4 via the previous instructions, and tried again, this time by uploading the v2.2.1.10 .img to the router from my computer. Same result; white screen, "DumaOS not loaded". So, another rollback, and another attempt to update to v2.2. Updating via the previous link's instructions, but using the v2.2.1.10 firmware results in another "DumaOS not loaded" loop. So, one final rollback. I'm back at v2.1.0.4 for now.

 

I'm starting to think there might be an issue with v2.2.1.10 that prevents DumaOS from running on my particular router. Note: I still have connection to the internet with v2.2.1.10 installed, and I can still load the legacy firmware that seems to run in the background of every installation, it is only Duma that won't load.

 

Let me know if you need any more information to help figure this out.
