- Common Fault Symptoms & Motherboard Diagnostics:
* Dead Phone (No Power / Low Current Hang): Phone does not turn on; on DC power supply, pressing the power button draws a low static hang (0.02A–0.04A) or 0.00A, caused by damaged internal PMU circuitry or absent 26 MHz system clock oscillation.
* Auto-Power-On on Battery Insertion: Connecting battery causes the phone to turn on or vibrator to buzz continuously without pressing the power key, resulting from a shorted internal power-switch transistor.
* Dead After Wrong Flash / Software Crash: Device does not boot or is stuck on boot logo after an incorrect firmware flash; recoverable via Miracle Box, CM2 (Infinity Chinese Miracle 2), or FlashTool using MTK USB COM port.
* Audio Failure (No Ringtone / Ear Speaker / Mic): Interruption in the internal audio driver block (frequently triggered by high-voltage charger surges or shorted speaker coils) leaves the phone completely silent.
* No Network / Emergency Calls Only: Failure in the integrated RF baseband transceiver or external RF power amplifier (PA) supply line prevents network registration.
