Yesterday a friend came by and asked me to demonstrate to him, my MiniM8S box running Balbes150 ubuntu image from SDCARD. So i did. After a few happy minutes he asked me to demonstrate to him LibreELEC running from the same box but from internal 8GB memory. So i shutted down the box, pulled out power adapted and SDCARD with ubuntu, and put the power adapter back so the box it will boot in LibreELEC. Then my friend noticed that the cables was a mess, and pulled out the power adapter while LibreELEC was booting, untangled it, and put it back. Well... the emmc got broken and the box didn't boot anymore to LibreELEC. Luckily it was booting fine to Ubuntu Xenial from SDCARD, and i had a backup from my emmc with LibreELEC from when i was creating my dd_backup script. I run the script, did it's magic and LibreELEC was back in life in 30 minutes, with all my configurations and plugins in place.
The image as you can see in the screenshot was compressed (what you cannot see is that is 221.5 MB instead of 8 GB) but this was not a problem for my box.
I spend a few more hours configuring some more my MiniM8S, and right now that is completely fine-tuned i'm taking a fresh backup.
