Arduino Nano not uploading code..I've tried everything!

Sketch uses 924 bytes (3%) of program storage space. Maximum is 30720 bytes.
Global variables use 9 bytes (0%) of dynamic memory, leaving 2039 bytes for local variables. Maximum is 2048 bytes.

avrdude done.  Thank you.

Problem uploading to board.  See http://www.arduino.cc/en/Guide/Troubleshooting#upload for suggestions.

This report would have more information with
"Show verbose output during compilation"
option enabled in File -> Preferences.

I'm using an Arduino Nano, I recently had a short circuit, but it still worked after that. Suddenly, the Nano wouldn't upload any code, but it could compile. I looked at all the forums (boot-loader doesn't work, I've tried reseting and my port is recognized, so my driver isn't the issue I think). I removed all my wires and am just using the Blink sketch with the built in LED to just figure out this issue. I know there are thousands of posts, but none have worked! Please help!

What has changed since it last worked ?

  • computer updated?

  • different USB cable ?
    -power led on ?

  • Arduino software changed on computer?
    -Nano could be dead, try another ?
    -computer USB port working ok ?

  • try to re load boot loader or program via the icsp connector with a programmer or Arduino as ISP.

  • what was that “short” ? How do you know the NANO worked ok afterwards ?
