BACKUP all data first. No guarantee this won't break your NVMe
Download the ISO from the Samsung SSD tools page.
Ex: wget https://download.semiconductor.samsung.com/resources/software-resources/Samsung_SSD_990_PRO_8B2QJXD7.iso
Install tools
```bash
sudo apt-get install -y gzip unzip wget cpio
```
Mount the ISO:
```bash
mkdir /mnt/iso
sudo mount -o loop /root/Samsung_SSD_990_PRO_8B2QJXD7.iso /mnt/iso
```
Extract and Run:
```bash
mkdir /tmp/fwupdate
cd /tmp/fwupdate
gzip -dc /mnt/iso/initrd | cpio -idv --no-absolute-filenames
sudo ./root/fumagician/fumagician
```
Reboot after the tool confirms success.
NVMe SSD-990 PRO Series Firmware
* (8B2QJXD7) To improve read-operation stability. (Release : December 2025)
* (7B2QJXD7) To address the intermittent non-recognition and blue screen issue. (Release: September 2025)
* (4B2QJXD7) To address reports of high temperatures logged on Samsung Magician. (Release: December 2024)
* 990 PRO I 990 PRO with Heatsink will be manufactured using a mixed production between the V7 and V8 process starting September 2023.
Mine was on 4B2QJXD7 and had all sorts of issues including ejecting itself from the proxmox host completely.
Moved all data off, beefed up heatsinks, upgraded to 8B2QJXD7 now things are much faster and cooler. No crash yet.
