| Fault | What to look for in the schematic | | :--- | :--- | | | Trace BAT+ (battery positive) to the main fuse (F1000) and to the PMIC. Check diode mode readings on VPH_PWR line. | | Overheating near CPU | Find the VDD_ARM and VDD_SOC power rails. Look for shorted capacitors (e.g., C1104, C1105). | | No SIM card detected | Locate the SIM1_DATA and SIM1_CLK lines from the CPU. Check for broken pull-up resistors (R2501, R2502). |
