I'm using version 2.0.0 of the Android version of the device manager app. When I select my device from the list to do a DFU it immediately closes the app. Normally it would come up and let me select a file and perform a DFU on the device. I've uninstalled and re-installed the app and it still behaves similarly. I expected that if it couldn't do a DFU it would at least open the device and show some information that it won't work.
