Firmware upgrade 3.9.3 failed and now I have a brick

Firmware update to 3.9.3 went awry. The LCD stays on "Original Prusa i3 Prusa Research" and the fan will run a few seconds.  The factory reset procedure does not work.  My Octopi cannot establish serial comms to the printer. Any help or advice would be most appreciated.

Most likely another case of https://github.com/prusa3d/Prusa-Firmware/issues/2954 . Best solution: flash 3.9.2 again. Maybe add a comment on that Github issue too, so the developers know how often that happens.

I found a save on Reddit. It seems Prusa Slic3r has a port scan utility that detects the printer when avrdude cannot. I was able to complete the upload by temporarily moving my design/slicing workstation down into the basement closet next to the printer enclosure and connect locally. Sub- optimal procedure but at least it came back to life.

There is no chat button on that page for Prusa support. Just a link to take me back to this forum.

Bout the no chat - you will need to create an account on that site, you'll need the serial # on the silver tag on your printer.  Once you do that you will be able to engage with support.

That's the way.

I did say "login", assuming an account was already existing.
