    Modern MTK devices (Android 8.0+) employ Anti-Rollback Protection (ARB) and secure boot mechanisms. "Bypass Tools" function by exploiting specific vulnerabilities in the Boot ROM to disable these protections. A "Handshake Error" indicates that the communication link was established momentarily but failed to sustain the data transfer required for the exploit to execute. How to check :
