I finally managed to boot in Maskrom mode by shorting the clock pin (red circle on the picture) to ground, then loading the loader (rk3528_spl_loader_v1.07.104.bin) and u-boot with rkdeveloptool. 

救回来了吗？试试通过这个进入刷机模式试试。这个是我问电视盒店家给我的强制刷机点，我没试过。

I also added a usb3 ssd to the usb3 port.
To use it, you still need to load the kernel from an internal SD.
- flash the usb3 drive
- plug to the box
- e2label /dev/sda2 ssd
- change /boot/armbianEnv.txt : rootdev=LABEL=ssd
 
i also removed /dev/sda1 and /dev/mmcblk0p2 with fdisk
 
also, to install homeassistant/haos, here's the tutorial
 
Reboot and voilà !
 

This case is a clone of X88PRO:
 
 
However i use HK1 rom because regular x88pro lack of many features like saf  and without this dolphin-emu and others dont allow use external devices

another thing added in HK1 rom is cpu thermals, cpu load and memory load in status bar

but use this rom make frontal screen in tvbox dont work
 
 
In my case armbian works using information from this themes:

In other things can install xfce desktop, lightdm,  xorg, chromium, firefox, nm (for lan), xarchiver, dolphin appimage

also can enable panvk using this:

VK_ICD_FILENAMES=/usr/share/vulkan/icd.d/panfrost_icd.aarch64.json PAN_I_WANT_A_BROKEN_VULKAN_DRIVER=1
 
from here:
 
 
 
Add some images of tvbox, i make a mod (i dont have experience with tools) for add a fan, results are very impressive this tvbox at max stay around 79 to 80 degrees but now with fan stay around 35 to 45 degrees

Of course. I wrote a little script for it that shortens the process a bit. It is important to know that I am not working as a root user within armbian.
The necessary steps: 
   copy openvfd-fd6551.dts to /home/<username>    copy install_kernel_debs.sh to /home/<username>    copy OpenVFDService file to /usr/sbin,  AND set permission to 777 !    copy openvfd.service file to  /lib/systemd/system        sudo armbian-add-overlay openvfd-fd6551.dts    sudo /bin/bash install_kernel_debs.sh 
After reboot:    cd linux_openvfd/driver    edit MAKE -> KERNELDIR = /lib/modules/$(shell uname -r)/build    sudo make -j4    sudo make modules_install    sudo modprobe openvfd     sudo usermod -a -G i2c <username> Start the Service:
sudo systemctl enable openvfd sudo systemctl start openvfd

   
openvfd-fd6551.dts openvfd.service OpenVFDService install_kernel_debs.sh
