Samsung 980 Pro Crashes After Latest Firmware Update -- How to Downgrade?

[connor4312]

I updated the firmware on my 980 Pro 2TBa couple weeks ago, to version 5B2QGXA7. Ever since then, I've noticed my computer stop responding after a few days. Programs stop working and I can't open anything, even task manager. Today I finally caught the issue after just keeping Task Manager open all the time -- busy time on the 980 hits 100%, although there is no data being read/written: https://pbs.twimg.com/media/FLGZSOtVQAAuTF8?format=jpg&name=4096x4096

Diagnostics in Magician, including SMART metrics and the Diagnostic Scan, don't turn up any issues. Overprovisioning is set to 10%, and performance optimization is set to Power Saving. About 0.5TB of space is used, and the drive is not encrypted.

Is there any way to downgrade the firmware on this drive? Or do I warranty it and hope I get a drive with older firmware?

Which OS are you running? If W11 rather than W10 make sure you apply today's monthly update. That's meant to fix a known issue with W11 that causes this behaviour on nvme and SSD drives. I doubt you can downgrade the firmware though.

I'm still on Windows 10, version 21H2 (build 19044.1503).
