This article dives deep into the architecture of MTK addr files, their relationship with scatter files, and how mastering them can save you from bricking a device or help you resurrect a dead one. An MTK addr file (short for MediaTek Address File ) is a plain-text configuration file that defines the physical memory addresses and partition boundaries on a MediaTek-powered device’s flash storage (eMMC or UFS). mtk addr files
