I really dont know where else I need to check except that pin everything seems okay. And I have tried 3 different chips for there all same. I didnt understand. I remove the chip then it gives OL and no cut on the line there. But when I put the chip then it goes to short. The diode value must be aroudn 350 - 390 on pad 243 on PA_HB_K on line 50_XCVR_RX6_MB_UHB_PRX but it reads 0.01 after I put the chip. All the chips are broken and does this effect device cant get imei? Or should it be something else?
