Ok, so it seems that I did flash and need to undo it.
For what it’s worth, I don’t recall seeing that long post with all the warnings, and being so used to the frequent “click here to update” habit, I assumed it would just be another update. Yes, I am responsible for my gear and knowing what I’m getting into and should read the fine print. I’m a novice and will learn from this. Maybe a clearer warning on the “beta” status of products, and if they are optional or not.
I do appreciate the hard work from the team on chasing problems.
