Pp-var-usb-rvp [patched]

Before scraping solder masks, check the physical charging port assembly. Debris, moisture corrosion, or bent pins inside the port will prevent VBUS from ever converting into PP_VAR_USB_RVP . If the port is pristine, split the logic board (if dealing with a layered sandwich board) to access the test points. 2. Diode Mode Measurements

To understand why this matters, you need to understand the "Pickle" (Production In-Circuit Kernel Link Environment). Before scraping solder masks, check the physical charging

: Inject 4.0V / 2.0A onto the rail using a DC power supply. Use freeze spray or a thermal camera to pinpoint the capacitor that glows hot first. Desolder and replace it with a capacitor of matching capacitance and voltage rating. Blown Protection FETs / Logic Gate IPhone Charging Circuit Diagnostics Guide - Repair Wiki : Inject 4
