After a failed firmware upgrade, my printer is stuck at "Original Prusa i3 Prusa Research ..." and won't go any further.
Attempting to perform a factory reset in accordance with https://help.prusa3d.com/en/article/factory-reset_2216 doesn't change any indications.

I never did get it to factory reset. But throwing all the USB B cables I had out and replacing them with a new one did allow me to successfully flash the firmware, which solved all the problems.

Thanks for the information! Many flash problems are caused by unsuitable, too long or defective usb cables. The factory reset should work without usb cable.

Happy printing!
