Does the console still power on and boot fine?

Can you post photos of your soldering and can you confirm if R2C10 has a resistor soldered to the pads?

Thanks.

Thanks for replying. The console still powers on but its not booting fine. When i plug the power, it turns on by itself and shuts down after the xbox 360 logo. When I turn it on it would turn off by itself after a couple of seconds.

Here is the picture of my soldering:

Also, I've read something in a forum to put a external 5 volts to a specific capacitor to just power the nand. I did it and I think I soldered the negative wire of the external 5 volts wrong. when i turned on the external 5 volts, I heard a crackling sound and I immediately turned the external 5 volts off. I think I smelled something burned but by looking closely to the board I didn't see any burned components. What I can only see is a lump on the southbridge.

Here is a photo of the southbridge:
