So I tried the official Armbian version as described here in the thread, I have an Alfawise H96 pro + amlogic s912 Box with blue PCB, android 7 and ddr3 3gb ram.
1. I downloaded the following image: https://github.com/armbian/community/releases/download/202304/Armbian_23.02.0-trunk_Aml-s9xx-box_lunar_edge_6.2.0-rc3.img.xz#aml-s9xx-box
2. Write the image in a SD Card with BalenaEtcher
3. I changed the boot configuration in the extlinux.conf as follow:
LABEL Armbian
LINUX /uImage
INITRD /uInitrd
FDT /dtb/amlogic/meson-gxm-q200.dtb
append root=UUID=da0b20c3-cbcf-4b30-a157-cecc5d4d9a53 rootflags=data=writeback console=ttyAML0,115200n8 console=tty0 rw no_console_suspend consoleblank=0 fsck.fix=yes fsck.repair=yes net.ifnames=0 splash plymouth.ignore-serial-consoles
4. I copied the u-boot-s905x-s912 and changed the name to u-boot.ext
5. Put the sd card in the tv box, press and hold the reset button and plug in the power connector
6. Android Recovery starts
How can I boot the SD card?
