Several years ago I was able to revive a "dead" SSD simply by updating the firmware to the latest version.
I haven't had a dead SSD problem in a while though, so I don't know how common firmware issues are now.

Sometimes the dead SSDs will respond to a handful of commands anyway, meaning that you can attempt a firmware upgrade or reset. That’s the lucky case. But in the majority of cases I’ve seen, the firmware/controller goes into some hard lockup where it no longer processes SATA commands at all. I wish these things had JTAG ports...
