- Common Motherboard Fault Symptoms & Diagnosis:

* Dead Handset (0.00A or Stuck at 0.02A - 0.05A):

- Handset does not power on. DC power supply shows zero current on power button press, or freezes at low current due to missing VCORE or open PWRKEY logic.

* Primary / Secondary Line Short Circuit:

- Complete short circuit on the battery line (VBAT) or primary system rail (VSYS) caused by punctured internal MOSFETs inside the buck regulator stages.

* Bootloop / Freezing on Brand Logo:

- Phone attempts to boot, displays the brand logo, and restarts immediately due to voltage drop across the VCORE inductors when all 8 CPU cores activate.

* Excessive Overheating on Standby:

- The IC area warms up noticeably even when the phone is turned off or idle, indicating internal leakage across one of the LDO outputs.
