   git clone https://github.com/bkerler/mtkclient.git
   cd mtkclient
   pip install -r requirements.txt
2. Disable Windows Driver Signature Enforcement
   • Win + R → gpedit.msc → Computer Configuration → Windows Settings → Security Settings → Local Policies → Security Options → Devices: Unsigned driver installation behavior → Allow.
3. Install libusbK
   • Use Zadig → Options → List All Devices → MediaTek USB Port → libusbK.

4.4 Enter BROM Mode

Table

Copy

Model	Test-Point	Picture
OPPO A15	TP 1 under mid-frame	Photo
OPPO A16	TP 2 near SIM tray	Photo
OPPO Reno 6	TP 3 under vibrator	Photo

Steps:

1. Power off completely (long press 10 s).
2. Short test-point to GND using tweezers.
3. Plug USB → Device appears as “MediaTek USB Port”.

4.5 Unlock Commands

bash

Copy

python mtk.py printgpt           # List partitions
python mtk.py xflash seccfg unlock   # Unlock
python mtk.py reset

❓ 19. Frequently Asked Questions (50+ Q&A)

Q1: Can I unlock without wiping?
A: No. Bootloader unlock always factory resets.

Q2: Will I lose Widevine L1?
A: Yes. Use Magisk module “liboemcrypto-disabler” + re-certify via OTA.

Q3: Can I re-lock after rooting?
A: Yes, but SafetyNet will still trip (hardware attestation).

Q4: Does unlocking void camera warranty?
A: China/India: Yes. EU: Only software warranty.

Q5: How to check if bootloader is already unlocked?
A:

bash

Copy

adb shell getprop ro.boot.flash.locked

Returns 0 = unlocked.
