Hello, I am having some problems with my Pro mini 328. I soldered some straight headers onto the breakout pins on the side and right angle headers on the programming pins. I cannot upload a sketch because it says "not in sync". Also when power is applied to the board the default blink starts, but then increases in frequency exponentially until it just stops... I used a no clean flux pen to solder and this is what happened. So i tried to clean with alcohol carefully with a tooth brush, and it didn't help..
