We will try to prepare the Recovery SOP in Japanese version.Meanwhile, is it possible for you to try 1 or 2 NUC in your stock to see if the activation problem still exist?Our Engineer tried 4pcs last Friday and none of them have activation issue.We didn’t hear anything from Microsoft yet, we are not sure why we cannot see activation issue now.It will definitely help if you can let us know the situation in your side, thanks a lot!
