However, for low-level work—especially on and secure boot scenarios where GPT is inaccessible—the humble addr file remains irreplaceable.

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). However, for low-level work—especially on and secure boot
0x380000 0x500000 Read back this region to get a nvram.bin backup. If preloader is corrupted, you need to write a known-good preloader at address 0x0 . However, writing requires a scatter file; but you can use an addr file to first read back the corrupted region for analysis, compare it to a working image, and then use a patched scatter file to flash. 3. Combining Multiple Addr Files For complex operations (e.g., dumping only boot and recovery ), create separate addr entries: 0x380000 0x500000 Read back this region to get a nvram
