Code not getting uploaded to Arduino

Development Tools Uploading

Hello
I got my Arduino uno for only one month it was working perfectly fine and now when I try to upload any code nothing is getting uploaded. I tried three different pc and still same problem I tried different cable still same problem tried loopback test and failed tried to burn bootloader still same problem tried updating driver still same problem and Uninstalled Arduino ide and reinstalled it again and still nothing was working my Arduino was working before. I tried Arduino suggestions too and still not working. do I just buy a new one here is the error I get

Sketch uses 444 bytes (1%) of program storage space. Maximum is 32256 bytes.
Global variables use 9 bytes (0%) of dynamic memory, leaving 2039 bytes for local variables. Maximum is 2048 bytes.

Did you try the suggestions in the troubleshooting upload page?

What is the ttl-to-usb converter on your board? 16U2, FTDI...,CH340 or ...

For the CH340, the loopback test is non-conclusive. Even boards with CH340 that work perfectly can fail the loopback test.

If the board identifies itself as an Uno in the IDE, you have the 16U2. If it identifies itself as an ordinary COM port, you have another chip (e.g. the FTDI....).

In those cases your board is damaged and you will have two options

  1. Replace the faulty chip (and if it's the 16U2 you will need to reprogram it).
  2. Use an external ttl-to-usb converter (with DTR broken out) and connect that to the TX/RX pins of the Uno; connect DTR to the reset pin of the Uno.

Did the burning of the bootloader succeed? If not, you'll have to replace the 328P; hopefully you have a DIP version that is easy to remove/insert.

What was the project that you were working on when the uploads started to fail. Anything with motors, voltages different from 3.3V/5V?
