Running 5.2.1 tethered JB, how to upgrade to 5.3 untethered?

I have an ATV2 running 5.2.1 TETHERED JB and just saw the news about 5.3 untethered JB and I’m of course quite interested in this upgrade. I’m using a MacBook Pro running Mavericks.

I haven’t managed to upgrade though. I try to follow to the guide, but when it tells me to connect my ATV2 and I connect it, it tells me it couldn’t find any connected ATV2 :frowning:

What am I doing wrong?



Got it working!

I read somewhere that some people had problems on OS X, so I started an old Windows laptop. I also switched USB cable to a new one, so either of these changes may have done something to fix my issues.

However, I did the sensible thing and read through the guide again and found no changes there but then noticed the video guide. I highly recommend watching that, as it provides an extra step: You have to unplug the ATV at some point during the update.


Thanks! I’m happy to have an un-tethered ATV again and so is the wife :wink:
