Not bricking per say, but related. I have 4 ONNs. Three 4ks and a Pro. For some reason just in the last three weeks, my Pro (by far the most used) has been restarting on it’s own and sometimes going to Safety Monitor Dot update page on it’s own. Far preferable to bricking obviously since all you do is wait for it to restart or press the back button to get out of the Safety Dot page. Each happens usually once during a baseball game. Still strange. Hasn’t happened on any of the 4ks. I run a usb powered fan under this Pro too – not that I needed it, but just had it laying around anyway.
Also do not use Wolf launcher, which possibly has a connection to the bricking. Don’t feel any launcher is needed, though I can see how some would see this as part of the hobby.
