Good Day po!

Share ko lang regarding iPhone 7g issue

History:
Sabi ni tumer baka daw napuno at natatagalan sa pagboot pero hindi sinabi na may problema sa loudspeaker.
Buti napapayag sa presyo ko 5XXX PHP

Problem:
Matagal magboot halos 2 minutes nakahang sa apple logo at napansin ko rin na naka hide ang loudspeaker.
Heto ang unit tagal sa logo

Hindi ko na inapply jumper from pin C12 to R1103 kasi wala naman lamat linya

After install new audio ic then test
