Can't update iOS version nor restore my iPhoneXS

I was trying to update the current iOS version (14.2) on my iPhone XS to 14.4 using my MAC but I receive the following error:

The iPhone “XXXX” could not be updated. Declined to authorize this image on this device for this user.

I've received this error when trying to restore the IOS as well.


I haven't experienced such issues before


Could anyone assist please?

Hi Peter,

Yes, there is a recent backup of the iphone.

I'd tried to update the iphone wirelessly before trying to do that through the MAC, but it failed saying the iphone wasn't connected to internet (which was not true as the iphone was connected to WiFi and all the applications were running smoothly w/o any cellular data consumption).
