Okay, here are preliminary instructions, which assumes the locking SP is active:
- Download and extract
sedutil, which containssedutil-cli, then change to its directory:
https://github.com/Drive-Trust-Alliance/exec/blob/master/sedutil_LINUX.tgz?raw=true
tar -xf sedutil_LINUX.tgz
cd sedutil/Release_x86_64
- Use
sedutil-cliwith the--revertTPerargument to reset your NVMe drive to factory defaults:
sudo ./sedutil-cli --revertTPer password /dev/nvme0
The password parameter should be the SID password, which is likely the password you currently know.
