What sketch? You didn't say. You do have some posts left today, though. What I can see, you find it hard to imagine what it's like to be on the other end of your communications, a world away maybe, with no idea what you've done except for what you have posted.
For example, it is perplexing that you would be checking firmware versions and get hung up on that. So there must be more you're not telling us. One would expect someone in your situation to be attempting to upload wifi example sketches, or something like that...
Please read the forum guidelines that are found in the first few forum topics. You would see advice there like, "don't paraphrase error messages, post them in their entirety".
