Firstly, create a system image to a USB drive or a portable hard drive using the etcher. Then, insert the computer and start it up. The machine will first start from the USB drive. After entering the system, format the EMMC using the following command to enter UMS mode again.

sudo mkfs.ext4 /dev/mmcblk0
