Not sure of how to program an Arduino UNO R3 with a Pocket AVR Programmer

Using Arduino Microcontrollers
1

I have an Arduino project, and I have to flash the firmware of my Arduino UNO R3 16u2. I was unable to put it in DFU Mode, so i was recommended to use a programmer to flash it.

I bought a Pocket AVR Programmer (https://www.sparkfun.com/products/9825), and I'm not sure how to use it properly. I need to upload a .hex file to my Arduino, but with the programmer I'm not sure how to do it.

I appreciate some help or any hint!

Which part is unclear? You plug the programmer 6-pin cable into the 6-pin programming header adjacent to the 16u2 chip (top left in picture).

Then you upload the hex file you want.

Running the avrdude utility directly from the command line is the most straightforward way.
