Uno R4 WiFi -endless Skecht uploading & Firmware Update fail

Official Hardware UNO Family UNO R4 WiFi

Hey,
i´m running IDE 2.3.7 with a Uno R4 WiFi on Win11

Arduino R4 WiFi connected -> tryed to update Firmware - it failed.

Try to upload any skech -> endless update.

Serial Monitor is printing all time when connected - when i close it updating stil not possible.

Unpluging USB -> COM5 in Device Manager disappears - after replugging it - COM5 appears back.

In IDE when i want to check board info it says:
BN: Unknown board
VID: 0x303A
PID: 0x1001
SN: (null)

Trying to update firmware again: I can select the board and a firmware version and click update -> Update starts and shows Installing firmware endless... (at least for >1hour...)

Board was purchased at CONRAD Germany.

Any ideas?

Thanks :)

Do you not think this would cause problems. Either figure out how to fix that or buy a new board.

Thats why i ask for help here - how to do it. i mean i didn´t do anything unnormal. just regular firmwareupdate via IDE. Should not kill the board :)

I have been a programmer for over half a century, and I have NEVER done a firmwareupdate. I would have to study it to do it, as it is an advanced activity. Since it failed, that means the firmware is in an inconsistent state so it is unlikely to work. You need to perform a factory reset or an equivalent to restore the standard firmware.

See if there's anything in this thread which is of help.

The Uno R4 WiFi is an unique board, both the esp32 and the RA4M1. Why did you choose this board?

Why this board? well I thought its the board with the most posibilitys to play around. =)
And again; Opening the serial monitor i can see communication.
