thanks.

what about updating the firmware or I don't need to do this unless I want to run something besides OpenELEC or LibreELEC?

So is my analysis true that LibreELEC seems to be more bleeding edge with development than OpenELEC as far version release currency and beta updates and this project (ChromeBox) is moving in this direction too?

what I would recommend is:

• backup existing user data (to USB) using backup utility under OE general settings
  
• download GalliumOS ISO, write to USB, boot it
  
• install standalone firmware update
  
• create LibreELEC install media using their USB/SD creator tool
  
• boot install media, install LE
  
• restore backup from USB
  

LibreELEC is the preferred distro as OE is essentially dead IMO. The OE developers and project owner had a disagreement on the project's direction and administration, and all the devs left and formed LibreELEC. While some do still contribute to OE as well, LE is where all the work is being done, is the best supported distro. It's far more stable as well, given the amount of people working on it and their project philosophy regarding updates of internal components.
