I struggled with this same issue for a half day yesterday and finally got it.. Hopefully this helps someone! I have a pair of Samsung 990 Pro 2TBs w/ heatsink on an Asrock Rack W880D4U. Couldn't get my system to boot off the bootable USB based on Samsung's ISO. Kept getting this message "redfish: pushing firmware layout to odata server". Tried creating the USB stick with the tool in Samsung's instructions (unetbootin), tried it with Rufus, and tried it with balena etcher. I tried selecting MBR, tried UEFI, tried ISO writing the USB stick, tried dd writing, tried disabling secure boot, couldn't find any options for legacy boot, tried changing my primary GPU to CPU. Nothing worked!!! Was going to settle for pulling the NVMes and moving them to a Windows PC and updating with Magician, but when testing Magician on my own PC that has a 980 NVMe, it didn't even detect it :( Then I found this thread here.... Tried what OP suggested, but the utility gave me the "no supported ssds" message. Ugh. Came across another blog post searching for "samsung firmware usb wont boot" -- https://blog.quindorian.org/2021/05/firmware-update-samsung-ssd-in-linux.html/ Grabbed a docker container called "Ubuntu-Playground" from CA, launched the console, and ran the following commands: wget https://path.to.samsung.iso apt-get -y install gzip unzip wget cpio mkdir /mnt/iso sudo mount -o loop ./Samsung.iso /mnt/iso/ mkdir /tmp/fwupdate cd /tmp/fwupdate gzip -dc /mnt/iso/initrd | cpio -idv --no-absolute-filenames cd root/fumagician/ sudo ./fumagician And it actually worked... Saw both drives, updated them super quickly. Firmware didn't show up in unRAID until after rebooting, but it looks like I'm at the latest version now. 7B2QJXD7
