  • Judging by this, relevant circuits of the baseband wake signal might have malfunctioned. Take apart the phone and disconnect the battery. Remove the display assembly and take out the motherboard.

  • Attach the motherboard to the PCB Holder. Heat with Hot Air Gun at 200℃, air flow 3. Tear off the heat dissipation sticker on the backside of the motherboard.

  • Open the bitmap software. Locate BB_TO_PMU_PCIE_HOST_WAKE_L. Since relevant circuits of the wake signal might have malfunctioned, we can try to borrow the wake signal from WiFi relevant circuits.

  • Locate WLAN_TO_PMU_HOST_WAKE. We can connect PP101_E-1 (the test point of the baseband wake signal) with PP7611_W-1 (the test point of the WiFi wake signal) by jumping a wire.
