Hi, a quick start for this TV Box. There are several comments on the 905x3 thread but, for the sake of easiness, I've created this blank new thread.
My experience with H96 Max X3:
(1) Downloaded (from yandex) and burned Armbian Armbian_20.05.3_Arm-64_buster_dev_5.7.0-rc2-next-20200424_desktop.img
(2) Copied the /dtb/meson-sm1-sei610-ethfix.dtb into the SD card and modifed uEnv.txt to load that dtb and uncommented the 'APPEND' entry on aml s9xxx section
