Ive upgraded my unit. upgrade went smoothly. only takes a few seconds!
I spent more time making sure I had the plug inserted correctly than I did actually doing the firmware update.

I used a usb programmer from http://www.batemcu.cn
it’s a 3.3v unit that has a resistor you can remove to convert to 5V if needed.

Works without any modifications and it was only $2
