Hello,
I have the same situation here.
I tried to update via USB key and via the editor.
The first time, only the touchscreen was updated. It failed when trying to update the MixRack.
So I downgraded the touchscreen to get my system back. It worked.
The second time, it didn’t updated anything. A message showed up stating that the “Update failed!”
Any help would be greatly appreciated 
Thanks !
