Using "latest free download" versions of such tools carries significant risks:
Modern MediaTek chipsets employ a "DA" (Download Agent) and "Auth" (Authentication) system to prevent unauthorized firmware modifications. The MTK Auth Bypass Tool exploits vulnerabilities in the MediaTek bootloader—specifically the mode—to disable these checks. Version v35 (often distributed as part of larger suites like BMB or MCT) provides compatibility for newer chipsets and integrates common repair features into a single, free-to-use interface. 1.

These drivers allow the software to take direct control of the USB port, which is necessary for communicating with the MediaTek chipset before the standard OS drivers load. Using "latest free download" versions of such tools
If the wrong scatter file or firmware is flashed after a bypass, the device may enter a "Hard Brick" state, requiring physical EMMC/UFS intervention to fix. Once the authentication is bypassed, the tool can
Once the authentication is bypassed, the tool can send commands to the config or userdata partitions to wipe the Factory Reset Protection lock.
Many "free" distributions hosted on unofficial forums or YouTube links may contain Trojans or keyloggers bundled within the .exe file. It is recommended to use open-source versions from repositories like MTK-bypass on GitHub where the code is transparent.
