Flashing usually wipes your data. Always back up your NVRAM (IMEI information) before starting.
Many people search for “scatter file for all Android phones” but actually own a Qualcomm-powered device (e.g., Pixel, OnePlus, high-end Xiaomi, Motorola). For those: scatter file for all android phones
Why, then, can’t one scatter file rule all phones? The answer lies in Android’s architectural freedom. Google mandates a logical structure (e.g., A/B partitions for seamless updates, or dynamic partitions starting with Android 10) but leaves the physical layout to SoC vendors and OEMs. A Qualcomm Snapdragon 888 phone from Samsung has a completely different partition index than a MediaTek Dimensity phone from Xiaomi. Even phones with the same chipset may differ because OEMs add custom partitions for features like secure storage (e.g., Huawei’s nve partition) or diagnostic tools. Thus, a universal scatter file is impossible—but a universal scatter concept is not. Flashing usually wipes your data
