Having trouble updating to the latest firmware.

I'm trying to update my mk3s with prusaslicer runinng on windows 10, but it keeps timing out on the com port connection:

===========================================================

avrdude-slic3r -v -p atmega2560 -c wiring -P COM4 -b 115200 -D -U flash:w:0:F:\Downloads\prusa3d_fw_MK3S_3_8_0_2684.hex:i

avrdude-slic3r: Version 6.3-20160220-prusa3d, compiled on May 20 2019 at 18:52:49

Using Port : COM4
Using Programmer : wiring
Overriding Baud Rate : 115200
avrdude-slic3r: stk500v2_recv(): timeout
avrdude-slic3r: stk500v2_getsync(): timeout communicating with programmer
avrdude-slic3r: Could not open port: COM4

avrdude-slic3r done. Thank you.

=======================================================

So I'm on firmware 3.7.2 at the moment. I updated it from 3.7.1 using prusaslicer the same way I'm doing now. 

I can print with pronterface on the same com port. I can print with octopi. When I tried to update with the firmware updater plugin for octoprint , it also timed out.

I've only been using the printer for a couple of months so I'm still kinda new at it all. Does anyone have any idea what could be the cause of this?

I got it working after following suggestions on this discussion:

https://stackoverflow.com/questions/19645441/avrdude-stk500v2-receivemessage-timeout

Basically I clicked on the flash button in Prusaslicer immidately after I pressed reset button on the printer. I have no idea why this works but if you have the same problem, give this a try.

After flashing and the printer reboots, Prusaslicer will complaine that it lost connection with COM port, but this is ok. Firmware has already been flashed.

This tip just ended a morning of frustration for me. Thanks! Surprised this is still an issue after so many years.

My printer has been sitting for a few months, and I was worried it had died of loneliness or something. 😛
