avrdude: stk500_getsync(): not in sync: resp=0x00

enter image description here

I'm using arduino uno with ethernet shield.

I plugged a Led from digital pin to GND directly without any resistor if that was the problem, I do it often so far if that was the cause it just broke down now.

I already did the following:

• Port check

• Board check

• Driver check / re-install

• Cable check / renewed

none of it seems to work. If it is broken would my ethernet shield be harmed and be broken as well? Which should I replace.

Probably you are using Bluetooth. Solution is pretty simple. Just plug off TX and RX cable from Arduino and then upload your code. Then plug them in again.That worked great for me. For more listen this guy.
