Has anyone run into an issue with 8.1.79 when the power goes out for more than an hour that the system will not power back on correctly and all the light stay solid red? I have had 2 within a week do the same thing, I did find a solution, had to remove the SD with 8.1.79 insert SD card with 7.0.36, upgrade via the SD then power back down and re-insert the 8.1.79 SD card, and wa la it works, trying to figure out how to fix future issues
