I think (not 100% sure) that holding pwr button 20+s is equivalent to reset button,
call it "hard reset" ,, because there is a battery the cpu can get in a "confused" state
ie try to boot a SD with an A64 OS on it,,, you will think you have bricked it,,
no, it just needs a hard reset (& , of course, the A64 sd removed)
