LibreELEC-AMLG12.arm-9.80-devel-20190913121812-60568a1-odroid-n2.img on Odroid n2 has an green overlay, after reboot over splasscreen and the menu.
For the LE to work properly on the N2, I recommend using the SPI startup mode (in this case, all colors work correctly and you can use USB media to start the system quickly). I've put together a new version of SPIboot that properly supports starting from all media (SD USB eMMC PXE, the startup order can be easily changed to your liking or add new options like NFS). For quick tests, a USB drive is best (you can use any USB stick >=2 GB USB 2.0 or USB 3.0). For example, you can post in the eMMC system Armbian and quickly run the LE from the USB stick (or Vice versa , in LE eMMC, Armbian on USB 3.0). The speed of the system from a fast USB 3.0 medium is significantly higher than eMMC. Step updates on new SPIboot can be seen here.
