Unable to upgrade firmware

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.
