Then we need to see a schematic of what you have built.
Please post code directly here and not from third party sites.
You might want to look at this How to get the best out of this forum before you proceed any further.
We only know what you tell us, and without knowing what you have, we don't stand a chance.
Also what happens when you move across to the Com 7 menu.
I think you are using the IDE 2.x, Have you tried using the IDE 1.8.19 ?
You did post this in the Arduino stk Bootloader issues.
Hi @noobinthesecond. You described the Arduino board you are uploading to as "Uno". Something that can be confusing is there are multiple boards with "UNO" in their name. We need to be certain of exactly which one you have. The reason is that the problem might be caused by the IDE not being correctly configured for your specific board.
Please tell us which of the following boards you are attempting to upload to:
If you aren't sure which one you have, you can provide a picture of the board or a link to the place you bought it from and we'll see if we can identify it.
I concur. The fact that we see the "(Arduino Uno)" label in Arduino IDE's Tools > Port menu tells us that the firmware is present on the ATmega16U2 USB chip on your UNO R3 board. So this would indicate that the failure of the loopback test is caused by physical damage rather than it only being a case of missing firmware.
Unless you have the right tools on hand and the skills to use those tools, repair of the type of physical damage that is likely to produce this result is not very feasible. I suggest you attach a note to the damaged board describing what is wrong with it and put it in your electronics salvage bin. Then purchase a replacement board.
You can support the work Arduino does to provide free open source software, documentation, and hardware designs to the community by purchasing official hardware. It is available from these sources:
