Sierra 10.12.4, Xcode 8.3.1 and TVOS4 10.2 works for me, no issues after I upgraded from El Capitan. My certificate and profile was created on El Capitan, they still work with the mentioned versions after the upgrade.

Make sure you don't have multiple versions of the same certificate and/or profile installed. Not sure how the re-signer app handles it, but Xcode have problems determining which one to use when there are multiple versions to choose from, which often result in code-signing errors.

Thanks for coming back to me, I certainly do not have multiple versions of the same certificate. I even went so far as starting from scratch setting up xcode 8.3.1, as suggested in post 1 - troubleshooting - but to no avail. Looks like I am stuck with Kodi 17.0 for now, at least until I have been able to sort this out.

Impactor would have been an option if I could roll back my ATV4 devices to TVOS4 10.1 or 10.1.1 from 10.2, but that seems impossible.

In the meantime I will dig out my El Capitan 10.11.6 hdd and try again to codesign Kodi 17.1 for one of my APTV4 devices with TVOS 10.2.

Should that be possible? Any other ideas are most welcome?
