Smartthings vhome hub unlocked

Hi,
I have a ST vhome hub that has been unlocked by Vodafone. So no subscription is needed for activation. The problem that I’m getting is that every time I try to add to my ST account it gets stuck at 52% using an iOS device.
The hub was brand new and has never used still had the original security sticker.

Have been trying with Vodafone to get this to work for almost five weeks now.
Hoping someone here may have an idea or can help. I’m wondering if it’s a firmware issue, by that I mean it cannot get the latest from Samsung.

Hope someone has an idea or a solution.
Thanks
Wayne
