Seems to be also known as the HD18Q "black box". https://www.ebay.de/itm/153205410117 ("NEU MXQ S805 Smart 1GB+ 8GB Smart TV Box Android 4.4 Quad Core 1.5 G WIFI", seller "SILVESTRAS RUNTA Network Tech Co. Ltd"), EUR 14,99
I can boot with meson8b_m201d.dtb and wired Ethernet works.
U-boot thinks it is a 512 MB device. Linux does, too. The SDK used seems to be named "s805_0701_512M":

The board can be powered via USB.
The serial VSS is 3.3V though.
Serial console can easily be soldered to on PCB using
sudo apt install -y screen
sudo screen /dev/ttyUSB0 115200
Although it may not be optimal, the board can be powered from a CP2102 USB serial adaptor's 5V and GND pins. At least for debugging the boot...

EDIT: I can boot (at least other systems, this one is tbc) with meson8b_m201d.dtb and it shows 1G of RAM and wired Ethernet works.
s805_autoscript script starts the system from removable media, taking into account the particularities of each system. So maybe this needs to be fiddled with?

Booting that stalls at, as we can see on the serial console:

It almost looks like at the point where systemd should take over this does not happen. Does the kernel not find its userland?
Luckily it still boots from SD card. Booted from SD, we do:
root@vegas805:~# mount /dev/data /mnt
root@vegas805:~# cat /mnt/etc/fstab
#/var/swap none swap sw 0 0
#/dev/root / auto noatime,errors=remount-ro 0 1
#proc /proc proc defaults 0 0
/dev/root / ext4 defaults,noatime,errors=remount-ro 0 1
tmpfs /tmp tmpfs defaults,nosuid 0 0
root@vegas805:~# ls /dev/root
ls: cannot access '/dev/root': No such file or directory
I wonder whether /dev/root is simply wrong. For test, I change it to /dev/data and reboot without SD card.
Does not seem to boot either, this time stuck at

So, trying to flash back the original Android stock ROM:
root@vegas805:~# ddbr_restore_nand

STOP ddBR NAND
Lo and behold, the device now can boot Android again!
https://forum.armbian.com/topic/1919-armbian-for-amlogic-s805/?page=9 - it also talks about not finding the root partition when booted from NAND here: https://forum.armbian.com/topic/1919-armbian-for-amlogic-s805/?do=findComment&comment=59442
I'm trying to reuse my old OTT S805 box and succeeded in getting the 5.37 build to install to nand, but can't get either of the later ones 5.41 or 5.44 to run after they seem to install.
You do not have root mounted, so the system does not start.
I saw that but i dont understand why it fails to mount /dev/data and i go through the same steps with armbian 5.37 and it works fine.
TODO: Retry with https://yadi.sk/d/DnCkh3KBvAFES/Linux/Armbian/5.37
Install https://yadi.sk/d/DnCkh3KBvAFES/Linux/Armbian/5.37 on SD using Etcher
On the host computer, find the box on the network using
sudo apt-get -y install arp-scan
NIC=$(ifconfig | grep "Bcast:" -C 2 | head -n 1 | awk '{print $1}')
IP=$(sudo arp-scan --interface=$NIC --localnet | grep a8:16:04 | awk '{print $1}')
ssh $IP -l root
From there, continue as above.
The built-in USB hub seems to work here:
[ 4.194632] usb 1-1: New USB device found, idVendor=14cd, idProduct=8608

root@vegas805:~# ddbr_backup_nand_full
START ddBR NAND
dd: failed to open '/dev/dtb': No such file or directory
Do I need to be concerned?
Indeed, it seems like the backup is not complete, since there are fewer files than above where I had used a newer Armbian version:
root@vegas805:~# find /ddbr/
/ddbr/
/ddbr/bootloader.img
/ddbr/data.img
/ddbr/recovery.img
/ddbr/logo.img
/ddbr/boot.img
/ddbr/misc.img
/ddbr/system.img
So we should NOT proceed to flash the OS to NAND if we don't have a known good backup on another running SD card made using a newer Armbian version that has /ddbr/install/aboot/aboot.txt and the likes - or is it just a matter of running https://github.com/ggrandou/abootimg on boot.img to extract those files from there in case we ever need (to inspect or modify) them? Possibly I could just have proceeded here...
UPDATE: Use the build from https://projects.milankragujevic.com/amlogic/s805/2018-10-28/, which also contains the UVC kernel modules for webcams.
The source code for 9083xu.ko seems not to be available. Apparently this is an internal USB module and could be replaced with a Realtek one...
This is an attempt to force a kernel module to load that was compiled for a slightly different kernel - is the attempt futile?
mount /ddbr/system.img /mnt
cp /mnt/lib/9083xu.ko .
sed -i -e 's|3.10.33|3.10.99|g' 9083xu.ko
insmod /lib/modules/3.10.99/kernel/net/wireless/cfg80211.ko
insmod 9083xu.ko

Hello. I have the same model of tv box and I would like to tell me you which model of dts you used to see 1Gb memory. I managed to install nand with Armbian_5.37_S805_Debian_stretch_3.10.99_server_20180112 and meson8b_m201d.dtb but memory only sees 512.
Thank you for your work.
