If “Reboot from NAND/EMMC” is no longer available due to another skin, there is another alternative. Simply install this addon and run it every time you want to reboot the Android TV system. Works on Nokia 8010, Homatics, Dune HD etc. I can’t say if it works on other devices (untested).
Here the .zip file.
