I saw there was un update available and it successfully downloaded and rebooted but upon restart It starts the update then I get error, the system restarts after a couple of minutes and is not updated.

I have the following version

Android 6.0.1
Kernal 3.14.29
Soft Version V1.0.20170215


Tried several times to update with the same result.

I am going to try a factory reset then update OTA to see if this helps
