Hello,
I have the same problem too. The steps mentioned here don't resolve it.
Specifically, the problem occurs with the first pairing of a (new) Apple Watch on a (new) iPhone, so there aren't any options to delete update files, beta files, profiles, etc.
So:
- the first part of the pairing (bluetooth) is successful,
- the Activation process starts,
- then the Apple Watch App on the iPhone demands software update,
- the software update app tells me the current software version is up-to-date at version 2.2.1, no update is starting,
- the Watch is stuck in Activation mode, and,
- the only option in the App on the Phone at that point is to Cancel the update, which terminates the Activation process.
The watch (series 1) has been sold to me as (officially/certified) pre-owned and I'm running iOS 10.3 on the iPhone. The watch was bought off German eBay from an authorized seller and I'm running it on a Slovenian iPhone.
Please someone help.
Thanks!
