Lenovo offers an update tool for the NVMe SSD of my notebook (Lenovo X390). Unfortunately, the installation instructions (README.txt) are not sufficient to run the update tool.
What do I need to do to run the update tool?
Copy firmware update tool to local directory.
Add execution permission if required.
a. Irmfuu file may not be executable (w/o “x” attributeW to file) after copy.
In this case, run chmod + x irmfuu to add execution permission to the file and run
all after that to confirm “x” /execution permission is added to irmfuu.
Switch to root then run irmfuu executable.
a. Switch to root or add $user to root group to run sudo.
Reboot and check update result.
a. Run irmfuu show after system reboot to confirm update result."
