VVDI Prog Failed to Write Ford BCM R5F64524?

 Q: I have a problem with Xhorse VVDI Prog and reading R5F64524 Ford BCM cpu. I can only read it, but I cannot write and erase.  I dropped it from the board and I also cannot erase and write it.  And in the menu I choose as expected Vvdi prog.

Solution:

VVDIProg can only read this ECU, does not erase nor write it.
