So, this will be the thread as my understanding is increasing about armbian and my stupid allwinner board
Progress
config file for armbian config/boards/t95-h616-2gb-x.conf may be orangepizero2
defconfig for the board (can be obtained from either /proc/configs.gz or /boot/config-$(uname -r) from tvbox)
build uboot.bin
dts file (by installing dtc through termux and getting from /proc/device-tree or something).
boot0_sdcard.fex, sys_config.fex and u-boot.fex (by unpacking firmware img file can be achieved by using imgRePacker_206 from xda) what to do with them i dont know yet
Try hexdump0815 github u-boot for h616
then read more about linux kernel to be used
Rest will be coming
