I'd say: Use LibreELEC :-)

Even you follow my howto, you did most things terribly wrong, hehe - even the grub entry is not existent.

The error with the resume is wrong UUID in 

Code:

cat /etc/initramfs-tools/conf.d/resume 
RESUME=UUID=810a43dd-fec0-4d77-91ca-f79f5b7d76e5

Make sure it matches your swap partition, e.g.
[code]fritsch@t440s:~$ sudo blkid
