The car does not need the MFT software or central console to drive... it's basically a glorified radio. You can remove the fuse for the MFT, and completely power down the central console, and the car will still drive no problem.
So, when you said your car wouldn't turn on or drive, that would much more likely be a symptom of the 12V battery dropping below a level at which the car's support electronics can operate.
If turning the car on for only a little while (e.g., while you ran an update) and this caused the 12V battery to drop too low, this probably indicates that the 12V level of charge is borderline, or perhaps the battery has some other issue.
