Support,

there is some new firmware update for some samsung ssd (nvme ssm pcie based) that is built into this system i use. I dont have windows to upgrade that nvme samsung device and i can not really move this device over to a windows machine and attempt the firmware update there.

you don't need something fancy: #---firmware from https://www.samsung.com/semiconductor/minisite/ssd/download/tools/ #---first unmount SSD before proceeding sudo mount -o loop /root/Firmware/Samsung_SSD_980_PRO_5B2QGXA7.iso /mnt destdir="/var/tmp/fwupdate" # not on SSD, of course! mkdir "$destdir" cd "$destdir" gzip -dc /mnt/initrd | cpio -idvm --no-absolute-filenames #---create chroot env: mount --bind /proc $destdir/proc mount --bind /dev $destdir/dev mount --bind /sys $destdir/sys mount --bind /run $destdir/run env SHELL=/bin/sh chroot "$destdir" #---inside chroot: cd root/fumagician ./fumagician exit #---cleanup afterwards, umount etc.

i found some older discussions and even runthroughs about this matter, as apparently samsung does offer linux based iso images that apply the firmware for people outside the windows world. but they dont use these fancy fwupd or those tools and apis, but their own specialties and proprietary way to talk to the device. but all from a linux bootable iso.

but apparently that linux is dated and old and has all sorts of problems from needing an intel based storage controllers for sata for example and ps2 keyboard layers only and all weird stuff.

what runlevel or special way to boot the system would be best to be able to run these linux console tools and to not block the nvme device at all after some simple basic bootup of opensuse 15.4? maybe some safe mode or fallback in the opensuse grub2 menu?

the original iso on an usb key cant be booted on this dang machine it can disable secureboot but the samsung linux will never show any screen output and never goes anywhere beyond a black screen. this machine also apparently can only uefi, but no csm or bios way to boot.

additionally I also read about nvme-cl tool and even found some github project on collecting or sharing samsung firmware in .bin files but I wonder where they get those from as I never found any inside iso or the initrds etc.
