It didn't work for me. I believe the problem is: if your SSD is up and running, which means, you didn't have the problem yet, the firmware update works great and without a glitch. But if your SSD shows only 8MB instead of 80GB, 120Gb, etc, which means the bug affected it, you need to run the Intel SSD Toolbox and do what they call "Secure Erase" to return the SSD back to life. Then, you apply the firmware update.
But, the SSD Toolbox works only on Windows.. this is the problem.
I don't have a Windows machine (I had inside the broken SSD). Now I have to remove the SSD from my Mac, put it inside a closure, go to a friend's house, install the SSD Toolbox, then apply the firmware, put it back to my Mac and install MacOS... blah!
Better solution?
