I'm having trouble with the flashing of libreelec.
I have updated the Lollipop firmware okay. "Burned" the libreelec image above for the h-plus version - renamed the file to boot.scr and press and hold recover + power on.
I have tried 4 different SD cards of many brands (because it can be picky I think I read?)
But every time all it does is take me to the android recovery menu (where I can update from SD/usb but it wont accept .img files).
do you have the receiver for the Neo A2/3 remote plugged in ? If yes, unplug it before switching on your Minix. For me that does the trick (btw, on every boot not just when flashing)
