From past two weeks I am unable to burn my program into arduino uno r3 it's showing avrude error. I have tried everything from burning bootloader to upgrading firmware nothing is working. But while while upgrading firmware arduino is not entering into dfu mode. please anyone suggest me what to do.
Please do this:
- File > Preferences > Show verbose output during: > compilation (uncheck) > upload (check) > OK
- Sketch > Upload
- After the upload fails you'll see a button on the right side of the orange bar "Copy error messages". Click that button.
- Paste the error messages in a reply here USING CODE TAGS (</> button on the toolbar).

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.
If even overwriting the bootloader also doesnt work, try changing the processor.
Board and atmega 328p both are fine but there is problem in atmega16u2 I don't know wt the problem is.

Here are a couple of ways to re-burn the firmware on an atmega16u2. If you can not put the chip into DFU mode this may be the way to get it working again. You will need either a Arduino to use as "Arduino As ISP" or a regular ISP programmer.

I tried but still nothing is working
