This happened to me multiple times! I had to use the most updated version of chrome. Then had to exit out of the Green desktop app and refresh.

Then at that point could get to the two firmware options but whenever I hit “Confirm Version”, nothing happened.

Had to hard reset my Jade with the page still up and Jade plugged in, then it prompted a pin on the device and it started updating the firmware.

Long story short…had to turn off and on the Jade and try a few times but it eventually recognized the Jade and updated. Let me know if it works!!
