Phase 2: Firmware Flashing

Once the custom recovery is installed, the device is booted into recovery mode.

1. Wipe Data: The Data, Cache, and Dalvik partitions must be formatted to remove remnants of EMUI.
2. Flashing the ROM: The Custom ROM zip file (usually based on AOSP Android 10, 11, or 12) is transferred to the device and installed via the recovery's "Install" function.
3. GApps Integration: Due to Huawei's lack of Google Mobile Services (GMS) certification in later firmware, users typically flash a GApps package (e.g., OpenGApps or NikGapps) immediately after the ROM.
