An is a software application designed to read, write, or regenerate the IMEI number(s) on a MediaTek-powered smartphone. These tools communicate with the phone's baseband processor via the Meta Mode (also known as Download Mode or BROM Mode).
MediaTek chipsets (Helio G-series, Dimensity series, etc.) are popular in budget and mid-range phones from brands like Xiaomi (Redmi), Tecno, Infinix, Realme, Oppo, and Vivo. Unlike Qualcomm devices, which use an encrypted QCN file, MTK phones store IMEI data in the NVRAM (Non-Volatile Random Access Memory) partition.
