Hello all's, after several tries, I have functional path how to install latest Armbian with functional Wifi (perfectly work) and Ethernet (semi-functional (slow speed) to emmc, on Hannspree 80-AK000001G002 Android TV Box (RK3288).
!!! Use at your own risk !!!
Download Multitool https://users.armbian.com/jock/rk3318/multitool.img.xz
Create SD card with Multitool using balenaEtcher https://etcher.balena.io/#download-etcher
Download old Armbian image (Armbian_21.05.0-trunk_Rk3288_focal_current_5.10.27.img.xz) from balbes150 https://mega.nz/folder/j9QSDQSQ#6WpasOlbZYIInfw6yo4phQ/file/Sw5nHADY
Put image onto SD card, into images folder
Put SD card into tvbox, without attached HDMI cable
Power on tvbox
Wait for blue led blinking, after that connect HDMI cable
Create backup (for your own safety)
Erase flash
Burn downloaded old Armbian image into flash
Shutdown
Power on tvbox and complete initial setting (its important for emmc resize)
Power off tvbox
Download or compile (I prefered compile it own) latest Armbian image for Thinkerboard (be careful, must be Thinkerboard with RK3288, not Thinkerboard-2 !!!!)
Create SD card with Thinkerboard image (my recommendation is use another SD card)
Insert SD card into tvbox
Power on tvbox
Wait for boot complete
Complete initial settings
Using lsblk identify correct device address for emmc storage (in my case its mmcblk2p1)
Create mount path: sudo mkdir /tmp/emmc
Mount emmc into it: sudo mount /dev/mmcblk2p1 /mnt/emmc
Paste Thinkerboard files into emmc using rsync: sudo rsync -avx --exclude=/mnt/emmc / /mnt/emmc
Power off tvbox
Eject SD card
Power on tvbox
