KB 37 flash memory update problem

Recommended Posts

MacBook Pro (Retina, 15-inch, Mid 2015)

Processor: 2.5 GHz Intel Core i7

Memory: 16GB 1600 MHz DDR3

OS X HighSierra 10.13.5


TonePort KB37

Driver 7.6.7

Flash Memory 1.03

Line6 Monkey 1.77


Since my KB37 doesn't send midi data like modulation wheel or stop, play, record... etc.

I tried to re-install flash memory of 1.03 many times but doesn't work.

And shows this message:


Update failed.

(Code 80007204) Hardware device failed to enter update mode.


Plz give me a solution.
