@wesner0019, if you have winzip or 7zip or winrar, you should be able to right-click on the file and open it as an archive. If so, open the .tar file which is also an archive. Once open, open the directory you will see (dfu-util-0.8-binaries) and you will see the win32-mingw32 directory. The contents of that directory need to replace the ones in the directory on your PC.
I tried for hours to get this to work on my windows7 machine. The dfu-util would never see the core. I finally read on another post that the dfu-util doesnât like usb3 ports. I switched to a usb2 port and volia it works.
If dfu-util doesnât see it, change it to a usb2 Port (usb3 didnât work for me)
what do you mean exactly mean by
I did all the above but I canât find dfu-util.exe and when I write dfu-util in cmd I get:
âdfu-utilâ is not recognized as an internal or external commandâŚ
What is the problem?
@mohmhus, Windows has an application search path. Open a CMD prompt and type âpathâ and you will see what your present windows search path is. For dfu-util to run from any directory, windows needs to find it. It does this by looking in the search path. You need to add the directory where you put the dfu-util.exe (and supporting files) to the path.
You can find help on doing that here or by googling âwindows add to pathâ for example.
If you look at the end of the tutorial, i have already provided a link on how to do that
Thank you very much
The problem was that I didnât know what a .tar file is
Hello,
Is it working for Photon?
Thank you
Yes.
Thank you. I have tried it and no problem.
I tried to follow this step by step got the dll installed. then i hit this line. I did a search on my PC i donât have dfu-util.exe was that application supposed to install that as well?
I managed to get my photon stuck in safe mode was trying flash tinker to it. Ended up resetting it using my phone. Let me know how to get this to work because being able to flash code from my pc instead of the web interface will be useful seeing as the web interface doesnât have any form for source control.

Did you download dfu-util from the provided link, unpacked it and placed somewhere on your harddrive?
Or find it at the project home
http://dfu-util.sourceforge.net/releases/
For Windows, this might be interesting as well
I use CLI so it is installed. However it wouldnât let me flash anything with out DFU-UTIL which i did a search on my pc and doesnât exist.
I ran that drive program which i would assume would install the DFU-UTIL driver. Seams i missed where to get the DFU-UTIL from.
I will try this again the next time I manage to lock my photon in safemode.
That installer should also install DFU Util for you, hence the suggestion. It really does make things easier.
Thereâs also this guide that should tell you how to get DFU Util going manually:
You can also flash via particle flash --serial firmware.bin
But getting dfu-util is never wrong
And the place where to download it was provided in my previous post!
I am getting the following error when trying to install dfu-util. Can someone please give me some suggestions?
