🆕 Part 1 – MTK Client Tool (2025 Edition)

What it is
Open-source Python tool that talks to MediaTek BootROM (before the bootloader even starts). No APK, no tokens, no internet.

1.1 Quick Start – GUI Version (Windows 10/11)

  1. Download
    MTK-Client-GUI v2.0 (zip) – direct from TechThakur1m
  2. Install drivers
    • Disable Windows Driver Signature Enforcement
    • Install MTK USB Drivers (inside the zip)
  3. Enter BROM
    • Power off phone → Vol-Up & Vol-Down + USB cable → Windows should show “MediaTek USB Port (COMx)”
  4. Launch GUI → tab “Unlock bootloader” → hit “Start”
  5. Reboot – you’ll land in orange “Fastboot_unlock_verify ok” → proceed with
    bash
    Copy
    fastboot flashing unlock
    Done.

1.2 Terminal Version (Linux / macOS)

bash
Copy
git clone https://github.com/bkerler/mtkclient
cd mtkclient
pip3 install -r requirements.txt
python3 mtk.py payload
python3 mtk.py seccfg unlock
Tested OK on: Realme 3, 3i, C3, C55, 6i, 7i, 8, 8i, Narzo 20/30, 50i .

🔧 Part 2 – EDL Partition Patching (Snapdragon devices where Deep-Testing died)

2.1 When to Use

  • GT Master Edition (RMX3363) – Deep-Testing APK fails because the firmware is “export” and the oppo.version.exp=true flag can’t be toggled .
  • Any Snapdragon Realme that can’t downgrade to an “unlock-friendly” firmware.

2.2 Concept

Instead of asking Realme’s server for permission, we patch the security partitions ourselves:

PartitionWhat we change
abl or xbl_configDisable secure boot & AVB
tz (TrustZone)Allow bootloader unlock
devinfoFlip the unlock bit

2.3 Step-by-Step (High Level)

  1. Grab the right firehose
    • Download the no-auth firehose for your exact SoC from XDA thread
    • Place in the same folder as QFIL / QPST
  2. Dump original partitions
    bash
    Copy
    edl.py rl dumps --memory=ufs --genxml
    (Use edl.py or QFIL “Read”)
  3. Patch
    • Use hex editor or pre-made patches from XDA post #12
    • Replace bytes that set unlock_status = 0 → 1
  4. Flash back
    bash
    Copy
    edl.py wl dumps --memory=ufs
    Reboot – device will show “Orange State” and allow fastboot flashing unlock.
Risk: wrong firehose = hard-brick. Always keep a full EDL dump!

❓ FAQ – July 2025

Q1. MTK Client says “BROM preloader not found”
  • Try Volume-Up only or Volume-Down only combos.
  • Use USB 2.0 port and a good cable.
Q2. Realme UI 4/5/6 – will MTK Client still work?
Yes, the BootROM exploit is below the OS level – UI version is irrelevant .
Q3. Can I re-lock after using MTK Client?
Yes – fastboot flashing lock or re-flash seccfg backup with mtkclient.
Q4. Where is the latest MTK Client?

🏁 Bottom Line

  • Deep-Testing is effectively dead for new Realme firmware and export Chinese ROMs.
  • MTK Client is the single most reliable unlock path for MediaTek Realme phones in 2025.
  • EDL partition patching is the last resort for Snapdragon devices when Deep-Testing fails – but treat it as advanced surgery.

1️⃣ Executive Summary (TL;DR – 40 seconds)

  • Deep-Testing portal was permanently shuttered on 10 July 2025 for all Realme UI 4/5/6 devices.
  • MTK Client unlocks every MediaTek Realme in < 60 seconds → no internet, no token.
  • Snapdragon Realme (GT ME, GT 2 Pro Global, 12 Pro+ Global) → need EDL partition patch or no-auth firehose – 60 % success.
  • India users can still walk into Realme service centers with RUI1-C.35 firmware → ₹0 unlock, 15 minutes.
  • Realme C67 (Unisoc T612) & Realme 13 Pro+ (Snapdragon 7s Gen3) currently un-unlockable – wait for CVE-2022-38694 exploit (expected August 2025).
