Pour les <\/span>iPhone X No SIM Card Detected issue. <\/span><\/span>Take apart the phone and run the cosmetic inspection of the motherboard, and it<\/span>'<\/span>s a little bit deformed.<\/span><\/p>\n

Then we can measure the SIM card connector J_SIM_K, the measured diode value of pin J_ SIM_K_2 is OL, which is abnormal. <\/span><\/p>\n

\"\"<\/span><\/p>\n

From the circuit and bitmap, pin 8 of SIM card connector J_DEBUG_K is connected with pin F18 of U_BB_K by way of R1615.<\/span><\/span><\/p>\n

Then measured diode value of pin 8 on<\/span> <\/span>J_DEBUG_K<\/span> is 620, which is normal. <\/span><\/p>\n

So we can conclude that the line is disconnected between  <\/span>J_DEBUG_K<\/span> et  <\/span>J_ SIM_K_2.<\/span><\/p>\n

<\/span><\/p>\n

We can reconnect it with a jumper wire from Pin 8 of J_DEBUG_K to pin 2 of <\/span>J_ SIM_K_2<\/span>. <\/span><\/p>\n

After finished it, then make the upper layer and lower layer solder together, and assemble it and test again, problem resolved.<\/span><\/p>\n
