Post subject:  Help to recover bestoss ssd in Rom mode

I have 2 SSD m2 ngff from Bestoss and from one day to the next it went into Rom mode.

I'm trying to find the correct MPTool to try to recover but so far without success. I'll leave some information about the bad and good SSD, if anyone can help I'd be grateful.

I don't really understand - do you want to recover data or repair the disk?

I need to repair an SSD that is stuck in ROM mode.

The files on it aren't important.

I tried using MPtool, but the program doesn't recognize either the faulty SSD or the working one.
