Hi everyone! im trying to update the SO of a Smart Tv Crown Mustang with android 4.4.2. I put the android 8.1 ISO on a pendrive and made it booteable, however, i enter on the menu of the tv and click on "start from pendrive" (or something, my english could be baaad) right now the red light is intermitent, and the tv still with black screen. i tried restarting and disconecting the tv but it doesnt work
