I've discovered a repeatable crash. This happens on at least these models:
- Roku TV 5000X
- Roku 3 4200
- Roku TV 4k (which I now can't remember if it's a 6000X or 7000X)
I believe all are on 9.0.0 (and I'm currently looking at my Roku TV 5000X which is 9.0.0 build 4148-08)
If I let my 2D game (roScreen) sit long enough for the Roku screensaver to kick in (no visible screensaver, just blank screen), then via the Development Application Installer webpage portal I "Delete" the currently installed application, the Roku immediately crashes. The way I experience is the crash is that I first immediately get a connection error from PurpleBug from the 8085 connection, and then after a few moments of being frozen and unresponsive even to pushing Home, the Roku resets itself like a full power cycle.
EDIT - I tested again while not using PurpleBug, same crash.
