PALYGAP

Tested compressed backups today in x96 boxes, and backup and restore works as expected.
This is the box tested ( 2 of them )

No. The cause of the other. I updated the source code, but did not add the necessary corrections. Now for me the main task - the integration of assembling the images for the TV boxes in the main branch. It is not a quick process.
 
 
 
 
Need to restore either a full backup. Filmed in advance on a working TV set-top box. Either the presence of a firmware file for the USB cable (the sellers bad TV boxes is not given).
 
If You care about official support - note that is already written Igor.

I'll try to address general questions since Balbes build is unofficial Armbian port, but we are planning to merge it upstream, that at least some of the most popular TV boxes will be officially supported. That will bring some more choices and an added value.
 
- HDMI sound should work, for spdif don't know.
- Bluetooth could be enabled but it's generally problematic so the answer is: perhaps
- yes, but currently not as simple as on stock Armbian. Our stock installer is not yet ready nor tested on those boards. 
- when official support arrives, you will be able to choose Debian as a base, but only if you built it yourself. We don't plan to provide two different desktop version for download.
- yes, it's an XFCE
 
First officially supported Amlogic box will be Beelink GT1, since it sits on my desk. (thanks to @p-i-u.de for donation one).
