1. It's impossible to say without box opening. Just try with the image and see if it's working...
2. Download .zip file (you don't need .tar at the moment). Put it on SD card (do not extract zip file). Insert SD card into box. Put box into recovery mode using toothpick method (google for toothpick method if you're not familiar with the procedure). Choose "Update from EXT", select zip file from SD card. Wait. Reboot box.

You're a star, the update worked perfectly and I now have LibreElec on my device
The only issue I have now is that four of my remote button functions are transposed (volume up / down mapped to Home / submenu, rather than the other way round). Other than that it works like a dream.
Thank you very much for your help, I really appreciate it.
