Your colleague told you to read post.
The problem is that the frequencies are different. You have already downloaded the firmware. Now you need to process it

Or, on same Forum mentioned [Only registered and activated users can see links. Click Here To Register...]

If you actually were asking for older firmware to roll it back below latest V 4.60 (which the only one on Garmin's servers), go [Only registered and activated users can see links. Click Here To Register...].

Works perfectly on Alpha100 with version 8.60

Is there a software that does this job today with newer collars? I've heard stories of people successfully pairing eu devices with USA devices and vice versa and removing the regional block.

Hello, for new garmins i never see the firmware...

maybe works.
