Hello.
I have installed 9.2.0 on a UBS and booted on X96 Max 4/32 (with proper device tree), and I get green screen. Just as described here: Khadas VIM3 testbuilds
LG tv, tried switching different HDMI cable and HDMI ports on TV, no difference.
Cannot boot nighly build, getting a boot loop.
Adding: device is now based on Android9, with update, dated 20190926.
Update: tried to run nightly again with a tooth stick, and it worked. Coreelec loaded fine and no green!
