I've uploaded a NOOBS LibreELEC 9.0/Kodi 18a1 test build for RPi2, here: Index of /noobs/LibreELEC_RPi2/
This includes the shortened partition labels and renamed tar files (does not include the old tar files) - basically everything in NOOBS: shorten partition labels, add $DEVICE support by MilhouseVH · Pull Request #2243 · LibreELEC/LibreELEC.tv · GitHub.
If anyone can test this it would be appreciated.
I've got a branch for libreelec-8.2 with essentially the same changes, Comparing LibreELEC:libreelec-8.2...MilhouseVH:le82_fix_noobs · LibreELEC/LibreELEC.tv · GitHub - this branch doesn't require all the extra $DEVICE changes so it's basically just the partition and tar filename changes.
