This procedure (typo-corrected version) worked for me, to restore my SSD-file-system from eMMC within 15 minutes.

I use nano to edit conf-files in terminal
(doing backup-copies before modifying is always a good idea)

  • df -h confirm that SSD is mounted at / (root)
  • sudo nano /boot/extlinux/extlinux.conf
    • change: root=/dev/nvme0n1p1 → root=/dev/mmcblk0p1
  • find path for internal storage (e.g. via filemanager): <path-to-emmc>
    • sudo nano <path-to-emmc>/boot/extlinux/extlinux.conf
      • change: root=/dev/nvme0n1p1 → root=/dev/mmcblk0p1
  • sudo reboot
    • df -h confirm, that eMMC is now mounted at /
  • format SSD ext4 (e.g. via gnome-disks - quick-format)
    • volue name rootFS, internal disk for use with linux systems only (ext4)
  • download and extract this zipped script
    • the script uses rsync to copy and then undoes the manual modifications in the conf-files
      • sudo ./change_rootfs_storage_direct-emmc_to_ssd.sh /dev/nvme0n1p1 … some minutes
  • sudo reboot
  • df -h to check if ssd is correctly mounted as / again
