Issues trying to update firmware
I just finished the MK3s+ to MK3.5s and I cannot install the firmware update. I have copied the .bbf file to the root of the Prusa thumb drive, rebooted the machine and it just beeps at me, warning I should update the firmware.
I would try updating the firmware from the slicer, but not sure how the USB connection would work. Which USB port would insert the USB cables?
Please help.

RE: Issues trying to update firmware
I connected the PC to the printer via USB cables and attempted to flash the machine via Slicer and the USB cables. The Slicer is asking for a serial port and will accept no values. Also, should the firmware update file be a hex file instead of the bbf extension? If so where would I find or create the need hex file?
Thank you
