Rooting the device repeatedly, we find when white apple appears, baseband S3, S4, S5 voltage can be instantly measured with power supply besides S2, but we still can measure the ground value on S2, is it the baseband power failure? Remove the baseband power supply chip, by the way of measuring its pin, it is found that the 91 and 97 pin of the baseband power supply chip are blocked. so we can see the problem has been found here, as shown in picture 7-4-7, 7-4-8.
