Prerequisites
Battery charge: ≥60%.
USB cable and PC with USB drivers installed.
ADB and Fastboot installed on PC.
Official Global firmware package for the exact model (ColorOS Global ROM).
OEM unlocking and bootloader tools (if required by Oppo variant). Some Oppo/Realme phones require official unlock permission or special unlock tool.
