My main use is Kodi Video. I use Netflix and Amazon Prime Video too. I sideloaded each of those. The Kodi Version 15.2 installed with the box is 'special' and steers you to pay services and removes and limits some addons. A sideload of Kodi Jarvis 16.x failed and you have to uninstall Kodi 15.2 first. If you want to clone a different box, make an XBMC backup and restore. Were I to do it again, I would likely install SPMC Kodi Forkhttp://spmc.semperpax.com/ You can keep the stock 15.2 and run SPMC at the same time.
I didn't like the launcher and chose Nova Prime. Long press on the left mouse key or menu button will behave like screen press on phone.
Without a recovery or recovery image, I am reluctant to make many changes to /system. If I make a mistake, I don't know how to recover and vendor has not been responsive to pointing me to recovery image.
The Settings App is a pain. I used Quick ShortShortCutMaker https://play.google.com/store/apps/d....quickshortcut to make shortcut to the AOSP settings app.
I didn't like the unknown to me Supersu installed. I installed a more standard Supersu and then I was able to get to the settings and permissions for Supersu. Were I to do it again, I'd try QuickShortCutMaker to find a shortcut to the installed SuperSu.
Some apps, i.e. Titanium Backup did not fit the screen properly and the overflow menu was not accessible. Menu on remote works. Editing build.prop and putting qemu.hw.mainkeys=0 in the last line solved the menu over flow problems.
You can reboot into stock recovery with ADB over WiFi.
