MTK Extractor

Purpose & User Intent: The tool enables structured extraction of MTK (MediaTek) firmware data from binary images or device dumps. Target users are firmware engineers, security researchers, and service technicians working with MTK-based devices. Use cases include firmware integrity validation, reverse engineering, archival data collection, and preparation for repair workflows. The core value is consistent, MTK-specific data extraction (partitions, boot metadata, keys) with exportable artifacts to facilitate audit, comparison, and further analysis.
Core Logic & Features: Domain capabilities include MTK-aware partition parsing (preloader, boot, system, recovery, vendor), binary data interpretation, checksum verification (CRC32/MD5 where available), and artifact export in JSON/CSV. Required features: input firmware image, MTK-aware parser, and export format. Optional/advanced features: batch processing, multi-version support, configurable output schemas, verbose logs, and selective field extraction. Inputs & Outputs: Inputs include firmware_file (path, required), device_model (string, optional), extraction_mode (enum: partitions|keys|both; required), output_format (json/csv; optional, default json), and firmware_version (string, optional). Outputs include extracted_data (structured JSON), partitions (name, offset, size, type), keys (hex-encoded values), and summary_metrics (counts, sizes, hashes). Algorithms & Calculations: The tool applies a deterministic MTK flash layout heuristic by reading firmware headers, locating partition table entries, mapping offsets, and validating data with checksums. It normalizes results into defined schemas and formats. Error & Edge Cases: Missing firmware_file triggers a defined error; unknown MTK version triggers partial data with warnings; encrypted keys may yield placeholders or require decryption keys beyond scope; corrupted images yield partial results with data integrity indicators; memory limits trigger chunked processing. Industry/Region & Localization: Uses bytes and hex representations for addresses; supports global MTK-based devices; language-neutral outputs; no locale-specific content beyond standard binary conventions. Assumptions & Exclusions: Assumes input is MTK-based firmware image or dump; excludes flashing capabilities, root exploit facilitation, or decryption of restricted data without provided keys; not a general binary analyzer outside MTK contexts.
