If I understand correctly wouldn't this overwrite the first set of headphones by updating the remote again? ....or do you mean after the first set of headphones have updated....turn them off then continue (on the same update) to update the second set of headphones?
Here is the problem I think.
If following the instructions when it asked if you have another pair of headphones,,,there is no prompt telling you to turn off the first pair that were upgraded,,,,and when you turn on this second pair and proceed--- this is when you experience it seems locked up headphones.
So what I said orifinally in the post above,,,,just update one set of headphones,,select no you don't have another set.
Update is finished. Turn off updated headphones.
The just do another update using same remote or another,,and get your other headphone remote and turn on when directed,,,and all will be fine.
Will be taking fewer chances here of a meltdown.
I would hate to have to send my components off to any place to due a problem created with update.
Funny thing is Mr Sabisch tells folks it seems about this in is bootcamp,,,but why hasn't Xp fixed the program( adding a prompt to turn off headphones that are already updated),,and also placed a warning in the operators manual.
Makes too much sense I guess.
Or have a way to override the headphones to be able to save face,,instead of sending them for the undoing.
