I have a O3DS XL. A friend was "helping" me with the hardmod and apparently,he fucked the DAT0 testpad. But that isnt the problem: Apparently,he followed soldering in the another two points (without success becouse he didnt use flux,it are a bit damaged but i checked them with a polimeter and they work). I think he followed soldering with the testpad in the welder,the copper of the testpad molten and now there is an shortcircuit between the CLK and the CMD. How can i take off that copper? Thanks.
