I have met this problem today trying to update Modfactor firmware from v5.2.5 to the last beta version v5.2.6 via USB from the H9 Control soft running on Win10. However I was able to update SPACE and Timefactor just few minutes before with the same configuration.
When updating the Modfactor displayed a “Bad !!!!” message at average 5% of the writing procedure, then it stop and won’t start again. It started only in Update mode. And the Initialize procedure didn’t work.Then I tried to update via “Eventide Direct Updater” software and I had the same things. . Then I tried to update via MIDI with both “H9 Control” and “Eventide Direct Updater” but these 2 soft was no able to connect successfully to my Midi interfaces. Then I realized that Ableton Live was running in the same time on my computer, so I stopped it and retry to update Modfactor directly from the “Eventide Direct Updater” soft via USB and it worked fine.
