Roku 3 - Micro SD Card format fails
My Roku 3 accepts my Sandisk microSD 2 gb card and the microSD card detected - format-cancel screen comes up. However, when I select format, the screen quickly shifts to the channel lineup screen. ...

While an SD card would be of some help, the bigger problem is your Roku 3 is now 8 or 10 years old, depending on the model number. It's really a slow device compared to the newest models. The Roku 3 was a fantastic player for many years, but it simply can't keep up with the newest apps written in a language that didn't exist (or was in its infancy) at the time your player was new.
The SD card won't work with the formatting done on the computer. Rather than formatting it again in your computer, instead delete the partition and let the Roku work with a raw SD card. On Windows you can delete the partition using the Disc Manager app.
I'm having a similar issue. I have a half-dozen Roku Premiere+ (model no. 4630X). I bought a 5-pack of cheap micro SD cards.
I put one card in one of the Rokus, and when it was powered back up, I was given the dialog to format the card. I accepted "format" and it took about 2 minutes to finish. After that, it apparently worked without issue.
I put a second card in another of the Rokus. When it was powered up, it did show the format/cancel dialog, but only for a second or so. The dialog went away very quickly, not giving me time to select "format." I haven't tried all of the other 20 combinations, but every other Roku and micro SD card combination that I've tested has had the same problem.
When the format dialog vanishes, an ad for the Roku channel at bottom-left of the screen becomes active. Is it possible that the ad is somehow overriding or canceling the dialog?
