 Bigger Bigger  Smaller Smaller  Reset Reset

Hellow,
I need to uptade Atmega8U2 on my R3 Arduino using DFU mode and I found just this guide:
http://arduino.cc/en/Hacking/DFUProgramming8U2
This guide doesn't suit to my Arduino, I need a guide which suits to my R3 Arduino please.
Does anybody know where do I have to solder the 10K resistor? it's hard to say just by this picture:

Thank you.

About the R3 UNO, It seems that you don't need to solder the 10k resisiter. It already has the 10k resister.

Where do you see that?
I don't see any 10K resistor...

The only Uno that needs that 10k was the R1.  For windows with the Uno R2 and R3 have the FLIP software installed and short the DFU Reset to Gnd (pins 5&6 on the DFU ICSP header).  This should initiate the New Device wizard where you will have to install the ATmega16u2 driver (if you have an R3) from the FLIP software directory.  After installation of the ATmega16u2 device, then you should be able to run the FLIP and connect.

Personally, I find it easier to hookup to the DFU header with a programmer and AVRDUDE smiley-wink
