I have the same problem with a 2D42; bricked after trying to upgrade from the Hantek-2000 app.
I tried first with the rescue app; successfully put in DFU mode, but it failed with "bad state machine in firmware":
I tried a few more times, same error every time.
I then tried DfuSe Demo but all attempts to upload firmware failed:
Then it would not even enter DFU mode anymore; removed batteries, held F1 and inserted USB cable, power button flashes but Run/Stop button does not light up anymore.
How can I fix it? @amy?
