Cannot update firmware

I am trying to fix a mk2s. When I went to update the firmware to 3.2.3 through prusaslicer I got "Flashing failed. please see the avrdude log below." The screen, which was previously working, now shows nothing but rectangles. There is no 

The avrdude log output:

"avrdude-slic3r -v -p atmega2560 -c wiring -P COM3 -b 115200 -D -U flash:w:0:C:\Users\setha\Downloads\delete\prusa3d_fw_3_8_1_MK3\prusa3d_fw_MK3_3_8_1_2869.hex:i

I contacted the Prusa helpline, who were very helpful and figured it out. I accidentally flashed the wrong firmware the first time, which screwed everything up. To put the correct firmware on, they had me download "Xloader" and in the options use device "Mega(ATMEGA2560)" to flash the correct firmware.

Beware though: I may be forgetting a step in their directions here, and I do not know the risks involved in this method. I would suggest contacting Prusa for proper directions.

 

Good luck!

RE: Cannot update firmware

I am having a similar problem.  I've tried to factory reset and I don't get a menu.  I don't see the text "Original Prusa i3 Prusa Research" on the display.
