I am having the same issue with my Ultra 4640. I have tried various methods to fix the problem, but the device inevitably goes back to Recovery Mode. This seems to be a widespread issue, one that occurred recently around the same date for each user. It certainly seems like a software issue, perhaps a bug in a recent Roku system update.
I just got off a chat with Roku support. In the end I was told to buy a new Roku. I questioned why, basically Roku send out an update and now I have to buy a new Roku? The response was that they added features that my 4640x couldn’t handle.?! 🤬

Another Roku support person that has no idea what they're talking about. There's been no added features that the 4640 would not be able to handle. Even the much older Roku 3 and 4 are still supported with the latest OS version, and there's been no reports of any of them being bricked by an update. The 4640 uses the same CPU as several other devices from the same generation, and none of them seem to be bricked either.
