The main problem is that the Vim box arrived today with stock rom, i guess it was Android 6.0, and McGyver though well let’s press reset and function button, and press power and function button at the same time booting. And “voilá”. Done. Black screen, led always on(despite i turned it off in android rom that means it’s not even entering the SO, and the video output is dead as the screen enters in economic mode.
I’m really embarrassed right now.
