I would like to install LibreELEC-S8X2.arm-8.2.RC3-MXIII-PLUS from the link below:
on SD-Card on my MXIII-PLUS
I couldn't find a manual, could someone point me to an explanation how to do it?
I started mine with updating it to the latest of the manufacturer. (Had to do some searching the web).
This way the bootloader becomes more compatible with stuff used in the LE-image.
Then i found the "toothpick" method very practic.
Start putting the image on a SD card (rufus / usbit as a DD-image), insert it and turn the machine on with a toothpick keeping the reset button for a while.
(from memory) Once you see the boot logo, release the toothpick and you'll see stuff happening there.. (maybe a keyboard for confimation? I don't remember).
Then it reboots from the SD card and you can play directly from it....
Later when you decide it to be stable enough (and wipe that android), you can install it to the onboard flash (from the shutdown menu).
I couldn't find the "main-instructions" either, by the way.
