It totally worked! Best Christmas ever! Solved!

It's totally working (updating via BT !), so excited, in 10 minutes I expect to be able to call this one solved. I learned some things too, and did get the VM to do a successful DFU flash as well (I realized I was not using the sudo command because in Windows didn't need it).

I just installed VirtualBox and the Bitcraze VM .6 so I can try working through the Linux environment instead of Windows. My VM can see STM32 Bootloader when the device is plugged in via lsusb but if I try to run dfu-util it says 'Cannot Open Device'. Nothing new here, just trying anything I can to ...

Thank you, I tried the DFU using the command at: https://wiki.bitcraze.io/projects:crazyflie2:development:dfu Which was: dfu-util.exe -d 0483:df11 -a 0 -D cf2-2015.08.1.dfu It looked OK ("Download done"), but still in solid blue light state after disconnecting power and reconnecting battery.

I had also tried redoing the bootloader like this:

No luck yet. I haven't given up since it does let me run these commands, but I'm stuck.

Indeed I used the instructions here. I attached a screenprint of the output when I run dfu-util --list and the upgrade sequence. It appears to run successfully...but the device is stuck in blue light mode. Any ideas?

There is one more state I can get it to go into-if I hold power button and connect power until I get the 'slow blink' mode and let go. It goes into a 'alternate 2 blue light blink' mode. I still can't see it from my iphone though.

Today I received my CF2.0 and took it for a couple flights using my iPhone. Then I saw the 'Upgrade Available' and tried to upgrade. It said it would take 10 minutes...unfortunately my phone is set to lock at 2 minutes and I did not know that would interrupt the upgrade. Now my CrazyFlie is not work...
