- Common Fault Symptoms & Motherboard Diagnostics:

* Dead Phone (0.00A on DC Supply): Device fails to power on; pressing the power button shows 0.00A draw due to missing 32.768 kHz clock, open PWRKEY line, or burnt master buck coil.

* Low Current Freeze (0.01A – 0.03A Hang): Device starts initial power handshake but freezes due to an internal short or missing secondary LDO supply rail.

* Dead After Charger Surge: A voltage spike from an unbranded charger or vehicle charger punctures the charging section of MT6328V, shorting VBUS directly to ground.

* Auto MediaTek USB Port (BROM Mode): Screen remains black, but connecting via USB to a PC immediately registers as "MediaTek USB Port (COMxx)" because CPU boots into base ROM while flash memory (eMMC) voltage rails are dead or unstable.

* Heating On Standby: The chip becomes excessively warm upon connecting the battery, indicating internal gate breakdown on the main buck stage.

* Complete Audio Loss: Loudspeaker or microphone stops functioning permanently despite replacing speakers and flex cables, caused by a blown internal audio codec stage.
