Hold the boot keys (usually ) and plug the phone into the PC.
If the device is stuck in a boot loop, it may not stay in BROM mode long enough for the handshake to complete.
An MTK bypass tool handshaking error is rarely a sign of a hard-bricked phone. Instead, it is almost always a minor breakdown in communication caused by Windows drivers or USB port configurations. By systematically reinstalling your LibUSB filters, switching to a USB 2.0 port, and perfecting your hardware button timing, you can establish a clean handshake and successfully bypass the security layer.
Disconnect your phone, restart the MTK Bypass Tool, and try again. Step 2: Master the BROM Physical Connection Sequence mtk bypass tool handshaking error
Faulty hardware can cause intermittent data drops during the critical millisecond window of the handshake.
: Always use a high-quality USB data cable and avoid using front-panel USB ports on desktop computers, as they often provide insufficient power or data stability for flashing.

Windows often blocks unofficial MediaTek service drivers because they lack digital signatures.
Move your USB cable to a (usually black or grey). Instead, it is almost always a minor breakdown
The "handshake" is the initial communication phase between your computer and the phone's processor.
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.
Do not use USB hubs, extensions, or front-chassis ports on desktop computers. Plug the cable directly into the motherboard ports at the back of the PC.
