is a xt1670 logic board compatible with a xt1671 phone?
While disassembling I accidentally broke off one of the antenna "pins" (the one under the audio jack). I'll try to solder it on again, but in case I cannot, you think it will affect its proper operation too much? I cannot test it right now as I am waiting a replacement side buttons board.
