🛠️ 1. Prep Your Workstation Environment

📦 Hardware & OS Requirements:

Reliable PC: Windows 10/11 or Ubuntu 20.04+ with at least 8 GB RAM, SSD storage.

USB 2.0 port (or quality hub)—MTK devices can be finicky on USB 3.0.

USB cable: Use original or certified cable to prevent disconnections.

🧩 Driver Setup:

Windows: Install MTK USB VCOM & UsbDk drivers.

Linux: Ensure libusb-1.0 is installed and udev rules are configured so MTK devices are accessible without root.

💡 Pro Tip from the Field:

Test and confirm driver functionality by plugging in a powered-off device and running lsusb on Linux or UsbDkController -n on Windows.

---

🧱 2. Install & Configure MTKClient (or GUI Alternative)

🔧 Windows (Recommended Steps):

Install Python 3.9+ and Git.

Clone the tool, then run:

pip install -r requirements.txt


Use driver installer for UsbDk if not automatically added.
(github.com)

🐧 Linux Setup:

sudo apt install python3 git libusb-1.0-0 python3-pip
git clone https://github.com/bkerler/mtkclient
cd mtkclient
pip3 install -r requirements.txt
sudo cp Setup/Linux/*.rules /etc/udev/rules.d/
sudo udevadm control -R && sudo udevadm trigger


Add yourself to plugdev/dialout groups and reboot to complete setup.

⚙️ Virtual Environments:

Always use venv to isolate dependencies. This prevents conflicts if the tool is updated or used alongside other forensic packages.

🔌 3. Boot the Device into BROM Mode

Why BROM?

BROM (Boot ROM) is the lowest-level interface on MTK devices. It’s read-only, and no OS-level protection can block it. That makes it indispensable for forensic access.
(4ukey.com)

How to Enter BROM:

Power off the device (fully, not hibernate).

Hold Volume Up + Volume Down (or Power + Volume Up), then connect via USB.

Watch for “MTK” device detection in lsusb (Linux) or UsbDkController (Windows).

If it doesn’t show, try each combo or use crash exploit methods like kamakiri or SP Flash Tool.

💾 4. Dumping the Flash Memory

Why It Matters:

A raw partition dump ensures you capture forensic artefacts like deleted files, metadata, logs, and key components.

Commands (Windows/Linux):

mtk.py r boot,vbmeta,userdata userdata.bin


Dumps the bootloader, vbmeta, and user data partitions.

Process typically takes 15–30 minutes.

GUI offers similar functionality using menu selections.
(github.com)

Verifying Integrity:

Use MD5 or SHA1 to checksum the dump. Store checksum as evidence for integrity.

---

🔓 5. Extracting Encryption Keys

Why It’s Needed:

MTK devices often use full or file-based encryption. Decryption keys are stored securely and must be extracted to access data.

Simple Extraction:

mtk.py da generatekeys


This generates a keys.json file with hardware and encryption keys.
(forensicinstitute.nl)

For Robust Key Extraction:

Do not disconnect the device between dump and key extraction. You can run both commands sequentially in one session:

mtk.py r userdata userdata.bin; mtk.py da generatekeys


If GUI Doesn’t Support:

Run in CLI fallback mode for consistency.

---

🔐 6. Decrypting & Accessing Data

Tools:

Oxygen Forensic Detective, Belkasoft X, or others allow import of userdata.bin + keys.json.

In GUI: create device.ewc with partition path and key file reference; import from secure folder.
(github.com, scribd.com)

Unlocking Screen Lock:

These tools can attempt brute-force or dictionary attacks on credentials extracted.

🧭 7. Workflow Rundown

Set up drivers and environment

Boot device to BROM with correct button combo

Dump critical partitions (boot, vbmeta, userdata)

Extract encryption keys in same session

Checksum everything for integrity

Import dumps & keys into forensic tool

Decrypt & analyze user data

🎯 8. Field-Proven Tips by a 10-Year Forensic Pro

Log your terminal output (use --debug) for court-grade audit trails.

Perform dumps on secure workstations, not virtual machines, to avoid USB passthrough issues.

Keep batteries charged—device shutdown mid-dump = lost evidence.

Never flash partitions unless specifically required—wiping bootloader offsets your entire dump.

For weak encryption (FBE), extraction + import yields near-immediate access.

---

🛡️ 9. Common Pitfalls & Fixes

Problem	Solution
Device not detected	Reinstall drivers, try another USB port/ cable
Dump aborted	Run one partition at a time or use CLI session
Key extraction fails	Ensure the dump is finished and device stays connected
Forensic app fails to import	Confirm device.ewc parameters match file structure
Device encrypted with DAA/SLA	May require signed loader—currently unsupported

---

✅ 10. Final 👣 Steps

You now have a reproducible, court-ready forensic chain from dump to decrypted data.

Store all materials (dumps, keys, logs, checksums) secure and timestamped.

Document every action with time, command, and operator name.

If you’re handling a specific MTK chipset model (Helio G70, Dimensity 700, etc.) or require help creating device.ewc or brute-forcing credentials, I’m available to support your next steps.
