dd if=/dev/urandom of=/etc/crypto-sdcard/crypto_luks.key bs=64 count=1

mv -v /etc/crypto-sdcard/crypto_luks.key /etc/crypto-sdcard/crypto_luks_$(blkid -c /dev/null -s UUID -o value /dev/mmcblk1p1).key

cryptsetup luksAddKey /dev/mmcblk1p1 /etc/crypto-sdcard/crypto_luks_$(blkid -c /dev/null -s UUID -o value /dev/mmcblk1p1).key

/etc/ofono/ril_subscription.conf
as root (devel-su) and add
enableSimToolkit=false
to it. Then
systemctl restart ofono
