It seems you're asking to create a file or content based on the keywords:
mt6589 (MediaTek chipset), android scatter, emmc, txt, nnlin, exclusive.
From context, you likely want a scatter file for an MT6589 device using eMMC storage (not legacy NAND), structured as a plain text file — possibly with a custom note or exclusive configuration labeled nnlin.
Below is a valid Android scatter file for MT6589 (eMMC), extended with a section that marks it as nnlin and exclusive in the comments.

3.1. The Linearization Process
The proposed method involves three distinct phases:
Phase I: Physical Extraction (Exclusive Mode)
Accessing the eMMC via the eMMC Direct Access (EDA) mode or by dumping the EMMC_USER region. "Exclusive" in this context refers to bypassing the MTK proprietary handshake (DA handshake) to read raw sectors without initializing the translation layer.
Phase II: Scatter-Guided Segmentation
Using the scatter file parameters to isolate the USERDATA partition. Because the MT6589 does not support file-based encryption (FBE) natively (relying instead on Full Disk Encryption or none), the raw partition contains recoverable text artifacts. It seems you're asking to create a file
Phase III: Textual Linearization
This proprietary algorithm scans the raw dump for text markers (ASCII/Unicode headers) and reorganizes them.
- Scan: Identify block boundaries containing UTF-8/ASCII strings (SMS, Contacts, App Data).
- Filter: Remove non-text binary noise (executables, compressed textures) that fragment the linear view.
- Reconstruct: Reassemble the remaining sectors into a single, contiguous "linear" file.
Part 2: Why You Need This Specific Exclusive File
Most generic MT6589 firmware packages contain a generic MT6589_Android_scatter.txt that works for 90% of devices (like the Micromax A116, Lenovo P780, or Cubot One). However, the 10% edge case—usually OEM white-label tablets or carrier-specific variants from ZTE, Huawei Y-series, or Alcatel—requires the emmc_txt_nnlin_exclusive.
Symptoms of using the wrong scatter file: Part 2: Why You Need This Specific Exclusive
- PMT changed for the ROM: SP Flash Tool throws error
0xC0050003.
- NVRAM corruption: The device boots but shows "Invalid IMEI."
- S_DS_PM_TABLE_SET_DRAM_FAIL (0xC0050007): The preloader cannot map the DRAM region because the exclusive layout differs.
- S_SECURITY_SECIMG_AC_VFY_FAIL: The exclusive file contains specific hashes for the
sec.img (security partition) that generic files lack.
If you see emmc_txt_nnlin in your firmware archive, do not replace it. Do not edit it with Notepad++. Use it exactly as provided. The "exclusive" tag signals that the partition sizes (especially proinfo at 0x200000 and nvram at 0x500000) have been manually tuned by the factory engineer for that specific flash chip die.
1. Introduction
The MediaTek MT6589 SoC, released in the early 2010s, powered a vast array of mid-range Android devices. While obsolete in terms of modern application support, these devices remain significant in the context of digital forensics and data recovery. A critical challenge in analyzing these systems is the proprietary nature of the bootloader and partition management, governed by a scatter file (often MT6589_Android_scatter.txt).
Traditional extraction methods often fail to reconstruct the logical filesystem due to the non-linear nature of eMMC storage and the vendor-specific bad block management employed by MediaTek. This paper defines a method for "Exclusive Linearization"—a process of isolating and reorganizing textual data structures from the raw eMMC dump, rendering them into a coherent, linear format for analysis.
