USB stick? or USB cable to computer?
USB to computer had 0 results.
USB stick with update froze the Stage unit multiple times.
I’ve had this happen too. Anything in the USB port can cause freezes. Did you try it again after rebooting?
After rebooting and trying to turn the Stage on with the USB stick in, then rebooting and starting with the USB off, and again both ways two more times...it finally recognized the USB stick and began to install the update. Everything is working just fine now.
