Do this:
MINIX U1 / U9:insert SD card, plug in power cord. Then hold in power button for at least 6 seconds or until LE Logo appears.
Or this:
Terminal Emulator: boot to Android, insert SD card/USB drive with LE, install Terminal Emulator app (either from Google Play or
APKMirror), run it and type reboot update. Your box should reboot to LE.Be shure to prepare SD card properly.If Your device boots every time to Android it could be Your fault preparing SD card
Thanks!!!
