Thanks ? @yeinerfonseca
Do you know if the HDD installed in the MBP is the original Apple OEM HDD?
Just wondering if it’s something similar to what @vertical smile experienced?!?
If it is the original HDD I would honestly not know why the firmware wasn’t updated also?!?
In that case I would try to boot into Recovery/Internet Recovery and try to reinstall macOS High Sierra over the top of itself which MIGHT install the correct firmware!?!
Obviously that would take a while so maybe do that as a last resort and hang on for a while until someone may be able to suggest an easier troubleshooting method.
I hope you can find a solution soon, I bet you just wanna get on with installing the new SSD! ?
