My Roku Express+ (model 3910X on device; 3910RW on "issue tracker" screen) is unable to complete any operations that would normally be accompanied by a 0-100% progress wheel. It can still load its most-recently used applications, but it cannot remove any via the * menu and it cannot load any of my many apps that it does not have cached as "recent."
I have done device restarts, but I am extremely reluctant to do a factory reset: my primary application is the Spectrum app for my grandfathered skinny streaming cable package, and it will not be possible to reinstall it if I reset the unit. That app, Bally Sports (for Brewers), and Netflix are all still on the working list, but HBO Max and others would need to load.
The Express+ lacks a microSD slot, so no help there.
Current system software is 10.0.0 build 4195. Last update was on May 8, 2021; Last check was May 25, 2021. It hangs if I tell it to check for updates. I'm unsure of how to roll back the software version on this model and don't know if it would help.
I have explored several of the secret menus. The channel menu does allow me to successfully remove applications. I did that for a few expendable ones, but it did not make a difference for launching what I wanted to run.
I did find that the system is running hot, I think: mid 90s Celsius with or without an app running. The local environment is not hot, and ventilation is adequate and unchanged.
I can generate Issue ID #s, but this model does not have agent support and I can't find a means of submitting them.
Any ideas? I'm using this model on an SDTV with composite inputs; if this can't be revived, we'll be without service in that portion of the house. The 3910 is the most recent model with this capability. [Meaning "just buy a newer one" isn't exactly helpful.]
