Hello,
The procedure described by Members_oVJQCN7 is okay, but not complete. This problem occurs on computers with Intel CPU and the Intel VMD RST Controller(s) (Rapid Storage Technology) installed. This controller denies the detection of Samsung SSD('s) by the software in the downloaded NVMe SSD-990 Pro Series Firmware iso (Samsung_SSD_PRO_6B2QJXD7.iso). So, there will not be updated anything and the program exits without error message.
Also Samsung Magician, running under Windows, does not detect a new version of the firmware, while it is there. Samsung Magician just shows “you are currently running the latest version of firmware” with the outdated version number.
Solution:
First; make a Windows restore point, back-up your data and create a Windows recovery drive.
Anyway you have to make a bootable usb pendrive according to the procedure described by Members_oVJQCN7, and to remove the Intel VMD RST Controller too, before rebooting from the USB pendrive.
The rather cumbersome procedure for removing Intel VMD RST is described here. After completing this procedure Windows is restarted normally with the Intel VMD RST Controller replaced by the Standard NVM Express Controller. Despite this, Samsung Magician still won't show any need to update message. So, we are not ready yet.
Now, restart with the USB pendrive installed and enter BIOS again. In BIOS, change the boot priority so that the USB pendrive is the first boot device. Also disable "Secure Boot Mode" and/or switch from "Windows EUFI Mode" to "Other OS" or something like that. After all, the OS on the bootable USB pendrive is Linux. Register all original BIOS settings, you changed, for resetting later.
After booting from the USB pendrive the software will ask you to press any key or to confirm with “y” to continue for several times. Next it will detect the SSD('s) and it updates the firmware of the SSD’s, if more then one, one by one after your repeated confirmations.
When the update is completed, restart your computer, remove the USB pendrive immediately during POST and enter BIOS again. Reset the switches to the "Secure Boot Mode", the "Windows UEFI Mode" and the boot priority to "Windows Boot Manager" first, or whatever they originally were.
DO NOT enable VMD in BIOS now (You disabled VMD in BIOS before by the first procedure). Enabling VMD will lead to a serious boot failure (inaccessible boot device), because the VMD RST driver is no more there.
Windows will start up, after exiting BIOS, normally, but now with the Standard NVM Express Controller as Storage Controller. Samsung Magician will show now again that you are currently running the latest version of firmware (and that is now indeed the actual 6B2QJXD7 and no more the outdated number).
Getting back to VMD is done by running under Windows the “Intel Rapid Storage Technology driver installer”, as supplied by your motherboard manufacturer (recommended) or the Intel generic driver SetupRST.exe. SetupRST.exe is downloaded from here. This will reinstall the Intel VMD RST controller. It should enable VMD in BIOS automatically, but that can, if needed (because of a boot failure) be done manually too, by entering BIOS. However, reinstalling the Intel VMD RST Controller will also reintroduce the problem of failing to update the Samsung firmware and Samsung Magician incorrectly showing up to date status of outdated firmware, when Samsung publishes a new version of the firmware. Keep on using the Standard NVM Express Controller is worth a consideration for private users, since VMD is aimed at enterprise use.
