Also, note that many of these tools were created for the needs of repair professionals. As such, they may not always be updated for the latest devices. A scatter file from a different device often will not work, and the correct one for a new model can be hard to find.
Before making risky changes to a device, developers use MTK addresses to perform a "Readback." By inputting a starting address and a length, SP Flash Tool can extract a perfect image of a phone's current partitions (like the critical nvram or nvdata which contain IMEI numbers and network calibration data) to save as a backup. Structure of an MTK Address in a Scatter File
Manually edit the addr file to rename the partition. Use a hex editor or Notepad++ to replace the string, but ensure the address ranges remain unchanged. mtk addr files

One of the most common reasons technicians hunt for specific MTK Addr values is to perform a manual format. For example, if a device is locked by a Factory Reset Protection (FRP) screen or a forgotten privacy password, a technician can isolate the exact hexadecimal boundary of the frp or userdata partition. Also, note that many of these tools were
Never copy address values from a tutorial meant for a different phone model, even if both phones share the same MediaTek chip (e.g., MT6765). Always extract values from your specific firmware.
When a phone is stuck on the boot logo (bootlooping), corrupt data in the cache or userdata partitions is often the culprit. If the standard recovery menu is inaccessible, targeting the precise start address of these partitions via an Addr configuration allows for a clean, forced wipe. 3. Protecting IMEI and Baseband Data (NVRAM) Before making risky changes to a device, developers
