Haven't you gotten past that with a clean install of a later version?
No, and I haven't tried yet as it's a huge time-consuming pain to possibly have a solution. Each re-install involves all the albums the grand kids like, MS Word (which is done on the phone with an interminable input of about 8 or 10 sixteen digit numbers), et cetera. All of that to get a solution to "The audio function keys don't work". For now, the audio volume is being done with the Command key and the up/down arrows.
Will, I get around to it? Yes....but that'll be when I have at least an entire day to spend on it.
Sounds like maybe the same d/l's you've already had trouble with.
I think you're right, these didn't work either. I just thought it was worth a try in case I lucked out and my issue was related to something in the downloads.
