Alternative: If the dual-volume method fails, try holding only , only Volume Down , or all three buttons ( Power + Vol Up + Vol Down ). 3. Resolve Windows Driver Signature Enforcement
When you connect your MTK phone in BROM mode:
The "Handshaking Error" in MTK (MediaTek) Bypass Tools typically occurs when the software fails to establish a secure connection with the device's Boot ROM (BROM). This communication breakdown prevents the tool from disabling the Preloader or Auth protection required for flashing or repairing the device.
Low-quality or "charge-only" cables cannot handle the high-speed data transmission required for the exploit.
Use a high-quality data cable. Avoid cheap charging-only cables or magnetic cables.
: The specific MTK chipset might not be supported by the payload or script version you are using. Step-by-Step Fixes
Timing is critical when forcing a device into BROM mode. If the phone boots past the BROM screen into the charging animation or standard boot cycle, the handshake will fail. Open the MTK Bypass Tool and click or Disable Auth .
Unplug your phone, restart the MTK Bypass Tool, and try the process again. Solution 2: Disable Windows Driver Signature Enforcement
: The device is entering Fastboot or Preloader mode instead of BROM mode.
Different MTK chips require different entry methods. Volume Down works for Helio P-series, but Volume Up works for Helio G-series. Holding the button too long or too short sends the device into "Meta Mode" or "Test Point Mode," which responds with a handshake error.
Release the buttons immediately after the software detects the phone and attempts the handshake. 5. Clear Driver Conflicts via Device Manager
In the LibUSB window, quickly select the or Preloader device. Click Install Filter . Disconnect the phone and restart your computer. 2. Force a USB 2.0 Connection

During this phase, the bypass tool exploits a vulnerability in the BROM to disable security protocols. If the timing is off, the driver is unstable, or the hardware connection drops for even a millisecond, the handshake fails, and the tool throws an error. Primary Causes of the Handshake Failure
