I need help to flash back previous firmware of my SSD nvme 980 1To, or to get it working.
Samsung Magician notified me that a new firmware was available and I made the mistake to release the updade. I'm now with a write speed of 4MB/s. Before the update it was working fine at 2700MB/s ...
My PC is now hanging crazy.
I don't know if it's possible do flash back the previous fw version and I don't remember its number.
