The handshake process requires flawless, uninterrupted data transmission. Minor hardware instabilities will crash the script.
✅ If you're still getting the error, get a more detailed log of what's going wrong. Add the --debug or --debugmode flag to your command:
Windows often has USB filter issues that prevent the handshake; users on forums like often find that switching to resolves the error. Potential Fixes Reinstall Drivers: Use a tool like to ensure the libusb-win32 driver is correctly filtered for the MTK USB port. Hardware Reset: If the tool says "Handshake failed, retrying," hold the
Step 4: Disable Windows Defender and Driver Signature Enforcement
Let’s get to the practical repairs. Follow these steps in order. Do not skip the driver section. mtk bypass tool handshaking error
This is the most interesting and difficult cause. The MTK Bypass tools largely rely on a vulnerability discovered in specific chipsets (like the MT6735, MT6755, etc.). However, MediaTek has patched this vulnerability in newer chipsets (like the Helio G series or Dimensity series).
Follow these troubleshooting steps in order to resolve the issue and successfully bypass your device's security.

Right-click and uninstall any greyed-out or duplicate "MediaTek," "PreLoader," or "VCOM" entries. Restart your computer. 6. Use an Updated Bypass Tool Alternative
python main.py --debug --handshake-attempts 10
Release the buttons immediately after the software detects the phone and attempts the handshake. 5. Clear Driver Conflicts via Device Manager
Third, Ensure no other mobile software is running. If the device is totally dead (hard bricked), ensure the battery has enough charge to sustain the data transfer. Reattempt the Boot Key sequence carefully, watching the Windows "Device Manager" to see if a "MediaTek USB Port" appears and disappears, which indicates the timing of the handshake attempt. Follow these steps in order
In technical terms, "handshaking" is the process where your computer and your phone establish a secure communication protocol. When you use an MTK Bypass tool, the software attempts to exploit the device's BootROM to gain low-level access.
Swap to a high-quality data cable and use a rear USB port (on desktops) for more stable power delivery. Update Software
