How to update the firmware on the Samsung SSD M2 ?

1. Get the iso from Samsung possibly here
2. Extract the binary from the iso and run it. Note: you can do it live but a backup is recommended.

   mkdir /mnt/iso
   sudo mount -o loop ./Samsung_SSD_980_PRO_3B2QGXA7.iso /mnt/iso/
   mkdir /tmp/fwupdate
   cd /tmp/fwupdate
   gzip -dc /mnt/iso/initrd | cpio -idv --no-absolute-filenames
   cd root/fumagician/
   sudo ./fumagician
