Member: 2730637 Status: Offline Thanks Meter: 101 | iPhone 7 No Service is mainly caused by two reasons. The baseband PMU has been pseudo soldered. Or, the baseband CPU has shorted. For pseudo soldering problem, we can fix it by re-soldering the baseband PMU. As for the shorted problem, since the baseband CPU cannot be replaced alone, we need to replace CPU, baseband CPU, and baseband PMU at the same time or try board swap. |
