Hello, I've been trying to upload a program to my Arduino Uno but I can't. After looking for solutions on the forums, any of them solved my issue. Could anyone help me? I changed the cable, the computer and tried the program with another computer, but due to the difficulty that supposes changing the Arduino I would like to fix it.

Please if you know anything which you think could be usefull send it to me.

Remove any connections to pins 0 and 1. These pins are used for communication with your computer, including uploads. Connecting anything to these pins can interfere with uploads.

Make sure you have the correct board selected from the Tools > Board menu.

Make sure you have selected the port of your Arduino board from the Tools > Port menu.

Sometimes the port will be labeled with the board name in the menu. Other times it will not. If you don’t know which port is your Arduino, you can find it like this:

  • Unplug your Arduino board from the computer.
  • Tools > Port
  • Note the ports, if any, listed in the menu.
  • Close the Tools menu
  • Plug your Arduino board into the computer.
  • Tools > Port - The new port listed in the menu is your Arduino board.

Most machines do a sound when you connect / disconnect an USB device, if you don't hear that sound check for problems under Windows device manager, the arduino should show up as a virtual COM port.

Perhaps you have UNO which have 328p programmed with wrong fuses configuration, protecting it further to be accessed?

In that case you need some tools a s AVR doctor or similar or high voltage programmer in order to revive it.
