How to reboot iDrive

I am trying to install the REx hold software from DVDinmotion and am having trouble getting the car to reboot. The drive flashes as if it is being read just as the instructions imply, but their reboot procedure does not work. I can't get the new file to load....
DVDinmotion want me to reboot by holding the volume knob down for 15 to 20 seconds or failing that, lock the car for "10 min or more" to reboot. Any new procedure for an i3?

Having same problem. Have contacted dvdinmotion, will see what they say.

Have you by any chance figured this out?

I can't get the HSOC or DVDinMotion features to load myself.

I locked the car and walked away for ten minutes, when I returned the new software was working....
