Problem in Upload File System image

Please help me. I get an error when loading a file system image: “could not open port ‘COM4’: could not open port ‘COM4’: WindowsError(2, ‘\xcd\xe5 \xf3\xe4\xe0\xe5\xf2\xf1\xff \xed\xe0\xe9\xf2\xe8 \xf3\xea\xe0\xe7\xe0\xed\xed\xfb\xe9 \xf4\xe0\xe9\xeb.’)
The terminal process terminated with exit code: 1”

Could you try to reconnect device or restart machine?

Yes thank you. Reconnecting the device solved all the problems.
