Hi @Robin,
Thanks for the swift reply. I dug a little deeper and found the alternative firmware upload program in Python. This also didn't work and kept complaining about the Serial module. So I opened up my Device manager and found that the driver was not working for the FS mode. I downloaded the driver from the STM site and presto. Everything works now.
So I probably should have read the manual where it reads "Install the correct drivers" :-)

Hi All,
I got 2 Espruino Pico's through the Kickstarter campaign but hadn't found the right project for it yet. Yesterday I decided to see if I can use them in some Christmas decorations.
I'm currently on version 1.87 of the firmware and the WebIDE works, however, when I want to upgrade the flash I'm stuck. I get the red-green flashing lights, but when I proceed and click on Next in the flasher section I get a "Connection Failed" error. This is after I have selected COM6 (default for the WebIDE is COM5).
Looking at an alternative way to upload the new firmware I had a look at the DFU tool. I'm able to get the Pico into DFU mode (this is shown in the DFU GUI), but it will not allow me to upload the bin file as it states that it is not in the right format.
This behavior is seen in both Pico's.
This is what I see in the console
GET chrome.storage.local.OFFLINE_DATA = 0 bytes No navigator.serial - Web Serial not enabled >>> Connecting... Set Slow Write = true Unable to open device (connectionInfo=undefined) ERROR: Unable to open device (connectionInfo=undefined) ERROR: [notify_error] Connection Failed. >>> Connection Failed.Anything I'm missing? Where do I find the DFU files?
Any assistance would be highly appreciated.
Yes, it was windows 10 and because I could connect normally through the WebIDE didn't directly point me to an issue with the drivers.
