Its really unlucky, my guess is that Jumper didn’t flash the latest bios on some units due to lack of time. Again, it might well not be a bios issue, could just be the ssd being incompatible for whatever reason. If you have another device that supports m.2, you can check if the ssd works on that.
I’m not aware of the correct method to dump the bios and its probably risky to flash it in fear of bricking the laptop.
