Hi Paolo, sorry to hear it hasn't worked for you. Have you checked that your box model is T8SE - if you go to Settings > About. My box shows T8SE, Version 7.1.2, Kernel version 3.14.29, Build T8SE.Nougat.20181024.V8.2.3 There are no available updates so I assume this should be the same for all T8SE boxes. I have just started up my T8 SE > switched from CoreELEC to Android and run the terminal emulator app. typing in cat /proc/device-tree/amlogic-dt-id and pressing enter it reports p212_2gp212 which equates to the device tree image gxl_p212_2g.dtb that I used to setup the sd card for CoreELEC. please make sure your typing is correct.
