I have read and re-read the thread and am not sure if there is a definitive answer on how to "upgrade" the Openelec OS in a Dual Boot Chrome/OpenElec installation to get the new Kodi 15.0. As far as I can determine, it is a reinstall of the OpenElec.

Is it better to use the OpenElec upgrade function from within Openelec/Kodi or should you do a clean and install the dual boot utilizing the latest (if and when available).

That is what I thought and did. I also tested the Openelec update option from within Kodi and it also worked on the update from .5.95.2 to 5.95.3.

Fun to learn and experiment ...

FYI, it's explicitly listed on the ChromeBox wiki how to Update OpenELEC.

I understand that and followed it. I also wanted to test to see if then internal also worked and it did.

The ChromeBox information that you have put together is great and I thank you for your extraordinary efforts in that and maintaining this thread.
