L light constantly staying off + Arduino Sketch not uploading

Development Tools Uploading
1

Hi,
I got a Arduino Uno R3 quite a long time ago, when it came it didnt work, out of the box. Recently when i tried to see what is broken, it appeared on my PC as Arduino uno, I could even put it into DFU mode and yes, i tried to reprogram the Usb to Serial chip to no avail. Also the L light constantly stays off...I tried to wire up another Arduino to try to Burn a new bootloader, but the same thing would happen whem i connected them, the LED on the Good arduino would also turn off. Now im asking if the board is trash or is it maybe fixable?

Best Regards

Also, I ran the Loop-Back test and it worked...

Hi @diox323.

Please provide a detailed description of what you mean by "didn't work", including:

  • What did you do?
  • What were the results you expected from doing that thing?
  • What were the results you observed that did not match your expectations?
    • Make sure to include the full and exact text of any error or warning message you might have encountered.

Does it still appear on your PC as "Arduino Uno"?

Hi,
When i tried to program the board the Tx and Rx LED's turned on, but it never succesfully uploaded, After a long time i got an error message, I will put a Sketch to upload and wait when the Error comes up and copy it over to here.

Also yes, It still Appears as Arduino Uno.

These are the Error Messages:

Global variables use 9 bytes (0%) of dynamic memory, leaving 2039 bytes for local variables. Maximum is 2048 bytes.

This is with only that arduino connected to the PC and the programmer set to AVR ISP.

When i plugged the Arduino in it straight away didnt want to upload code, I was sure i was doing it right because i already had an arduino before this one. I am running it on USB power and when i mesaured the 5V pin and Ground with my multimeter it was about 4.3V, also the On LED is noticeably Brighter on my other Arduino.
