RE: MMI 3G very NICE BRICK

The firmware that I have installed is the K0900 for "MMI 3G+", when the one I had to install is the K0257 for "MMI 3G", now neither the sound nor the steering wheel buttons nor the MMI 3G works for me.

I have a tutorial that explains how to recover the MMI 3G using the PuTTY program, but I don't know how to connect this program with the MMI to change the "boot 0x680000" to "boot 0x78000" which is the one that corresponds to the navigation system .

Maybe this can help you
