Cnut Update issues

I am currently using cnut to update our sm’s to 7…0.7

Hower I can update the ap’s and some sm’s using auto aupdate.

The issue is some sm’s fail to update. The start the auto update process and go through just fine with no errors. They even reboot just like after being updated. But the firmware still remains the same.

However they dont come back and say update completed.

What can I do or has anyone seen this?
