Hi Chris,
 
Thanks alot! Up and running again, just like you said :).
 
Turned out it was the USB port, suspect it might be caused by the Windows 8.1 USB 3 issue. After connecting the N3 to a USB 2 port on the same pc, with the same cable, the N3 was recognized correctly.
 
Happy to help if you guys would like more info on my system. Basically, I am running Windows 8.1 on a Dell precision M4700 laptop.

Hi,
 
Long story short; I tried to clear my N3 with Netduino Update 4.3.1.0. The task didn't complete, so I killed the app and ended up giving it a hard reset.
 
Now I am unable to deploy new apps, the device is recognized correctly in bootloader- & normal mode. When I ping the N3 with MFDeploy it gives the following result:
 
Pinging... No debugger!

I can't use the Netduino Update tool to install V 4.3.2 as I have 0 write actions left, and the device
is still recognized as 'STM Device in DFU Mode' in bootloader mode.
 
If anyone can tell me if and how the device can be rebuilt, or confirm that I fully noobed out and bricked it, would be much appreciated :).

Hi Stefaan,

Let's get you up and running here.

The Netduino 3 mainboards are pre-programmed as Netduino 3s in OTP, so if you are getting "STM Device in DFU Mode" the most likely scenario is that your USB cable is worn out. There are other possibilities, but after doing a lot of insertion/removal cycles we have found that eventually those cables do wear out. [And if there's trouble communicating, Netduino Update won't be able to figure out what kind of board you have and will show 0 OTP cycles remaining.]

Can you try this for me really quickly?
1. Remove the MicroUSB cable from your PC and Netduino
2. Attach the cable to your Netduino 3.
3. Press the pushbutton on your Netduino 3 and then plug the USB cable into your computer.

Does that make the board show up for you in Netduino Update?

There is a backup procedure, in case the above doesn't work. If you grab a copy of the STDFU tools, we can help you manually erase your board, convert the .S19 HEX files to .DFU files, and then flash them onto your board. That's the old way of flashing, but it still works.

Chris
