I have followed the instruction step by step but I am unable to use DFU-util on my windows 10 machine.

Error writing firmware…Error: Command failed: C:\WINDOWS\system32\cmd.exe /s /c “dfu-util -l”  
‘dfu-util’ is not recognized as an internal or external command,  
operable program or batch file.

Is there an easy way to do this or do I need to try link the spark to my fedora VM

> @jcdude, I just had a Core do the same thing. I ended up flashing the cc3000 patch several times and different versions. I suggest doing the following using CLI (assuming you have it installed):
> 
> particle flash --factory tinker  
> particle flash --usb cc3000  
> particle flash --usb tinker
> 
> The first command updates the factory reset code. The second flashes the cc3000 update and should finish in DFU (flashing yellow) mode. The last flashes the tinker code over.
> 
> Try the first two, then do a factory reset which will wipe all your wifi creds. Then use CLI or terminal to setup new wifi creds and see if it connects then.

Thanks very much this did the trick
