Yes, I did try without restoring settings. Basically started with a blank slate and didn't get too far before the reboot loop. Here is what I did.
I originally saw the problem after installing a plugin so I reflashed and just restarted the GUI while at the home screen to replicate the reboot problem after a plugin is installed, no problems. I then scanned terrestrial channels and watched for a few minutes, everything fine at this point. I then restarted the GUI while tuned to a terrestrial channel and the reboot loop started. I also tested OpenATV on my ZGemma H7.AC and had the same results described in this post. Front display shows 2537 after reboot.
So that test minimized the possible variables.
The log file I provided was generated after I tuned to a terrestrial channel inducing the reboot loop.
