Apple iPhone 6s Plus has no 4G mobile network fault repair

Looking at the point bitmap, it is found that this inductor is a step-down inductor supplied by S2 output from the baseband power supply. The virtual welding of the inductor leads to the lack of S2 power supply for the baseband power supply, and the baseband power supply cannot be output for the second step-down to supply power to the baseband, so the baseband does not work, and finally the mobile phone has no 4G mobile network signal.
