I had big problems to update to the latest firmware 20130612 using MDM ver 20130612...on my ARM-based Megadrum-32 device.
Testing three different PC systems...using both the automated firmware update method and trying to doing it by hand (enable the firmware update on the MD) and then use MDM to upgrade the firmware. It failed to upgrade about 35 times with the Message "Megadrum is not responding"...standing at 0%.
Then I took and old signed jar file of MDM from 201209xx...and did the manual upgrade task...after two attempts...the upgrade process started...thank god!!
Anybody else who have seen problems to upgrade?
Best Regards
