The firmware upgrade from 3.13.2-7080 fails  

The firmware upgrade from 3.13.2-7080 fails

Since few months (I did few attempts) I can't upgrade firmware on my Prusa MK3S+ printer.

I tried

- two cables

- two computers

- Windows and Linux

- Prusa Slicer 3.7.x and Prusa Slicer 3.8.x

avrdude-slic3r -v -p atmega2560 -c wiring -P /dev/ttyACM0 -b 115200 -D -U flash:w:0:/home/<folder_name>/prusa3d_fw_3_14_0_MK3S/MK3S_MK3S+_FW_3.14.0_MULTILANG.hex:i

avrdude-slic3r done.  Thank you.

- avrdude on Linux with the command

avrdude -v -p atmega2560 -c wiring -P /dev/ttyACM0 -b 115200 -D -U flash:w:0:/home/<folder_name>/prusa3d_fw_3_14_0_MK3S/MK3S_MK3S+_FW_3.14.0_MULTILANG.hex:i

I did

- existing 3.13.2 firmware reset

- countless printer restarts

- countless computers restarts

- examined all options and possibilities listed in the Firmware updating issues (MK2.5S/MK3S+/MMU2S/MMU3) article

I can

- communicate with the printer using Pronterface (at least on Linux, I didn't check on Windows)

- print using OctoPrint on OrangePi SBC

Is any way to flash firmware? At the current firmware I have 'THERMAL ANOMALY' due to installed Revo hot end.
