I confirm functionality on MXQ 4K Pro + with S905X SoC (2G / 16G)
It was a bit of a hassle, but it's worth it. That box has a new life. It was no longer usable on Android. Boot from SD card 4 times failed. LE came up from the USB closest to the SD slot on the second attempt. Also installtointernal until the second time successfully.
LAN, Wi-Fi, BT, Remote control works.
Many thanks for your work!
