Looks pretty ugly!! It is possible this existing work is adding to your reset problem. Make sure to clean off all that old flux. Isopropyl alcohol or circuit board spray cleaner from Jaycar and small a brush is good for this. Also as suggested before, use a multimeter to bell out the tracks when finished. I found taking a photo of the board with the components removed is a good way to remember where the tracks go. The large caps cover the tracks and could leave you guessing what's connected to what.
