If you think about it the, MFT is nothing more then a computer and like all computers susceptible to gliches( power surges,and whatever else that may cause it to get corrupted signal)
just just like your home or laptop computer, you removed its power , (turning it off will not do it.,because there is power still going to the MFT SYNK memory) When you reboot it will clears them and takes you back to factory reset, just the way it was when you recieved it. Reloading your datd is a small price to pay if to clear your problems.
By disconnecting the cables,and shorting them together , you canot hurt anything. check it out. I have a 2005 Cadi.that a 12v lt cooler discharged the battery over night . After Jumpstarting the car , the engine and it's controles worked fine
but nothing controled by the computer functioned correctly. I removed the battery cables and shorted them together , this shorted the plus and minus busses in the computer discharging the capacitor and clearing memory of any error signals. Allowing car and onboard computer to function correctly when restarted
Like I said. Hard Core... just to get the MFT to work like it should.
I hate resetting the plethora of setting in the Edge.
repairing the phone and re-saving radio stations are bad enough. Don't forget the other settings...
Backup camera,
Auto Start,
Liftgate,
Lock/unLock,
Display brightness,
....
you get the idea.
