I was getting an error message when trying to Flash the modified nand.bin to my 3DS, and got the impression from looking online that it could be a bad solder joint. Here's where I screwed up: when trying to fix things, I had a blob of solder hit another area of the motherboard. Obviously I tried to clean it all up. After, I just disconnected the wires I had connected to hardmod, to see if any major damage had been done. Unfortunately, now it doesn't turn on unless it's connected to the power cord. I did a battery test, and the battery still has full power, so that's not the problem. How can I go about troubleshooting this problem? I have included 2 photos of the motherboard, where I got in there with a soldering iron. Do any of these areas that look messed up have influence over the battery?
