I could not boot version 1.8.2. Message:
cp: write error: no space left on device
*** Error in prepare_sysroot: mount_common: Could not mount /dev/SYSTEM ***
### Starting debugging shell ... type exit to quit ###
... and drop in shell. I think in my case the script that partition size change did not work. Version 1.6.5 and LibreELEC 8.2 boot successfully. dtb.img is the same everywhere. I tried two cards: 32GB and 64GB.
