Sounds daft but did you fit them (BR and Cap) the correct way round? I don't think there's much else that can blow F104 with J107 and J127 removed. It might be worth replacing them again to get F104 working.
Replace J208 and cut about 1 cm off each wire before connecting it to the new connector. Also check the male pins of J208, any green then it should be replaced as well.
