+DEMOSTRACIÓN DE HERRAMIENTAS DE ANÁLISIS HEXADECIMAL Y MODIFICACIÓN MTK
+=============================================================================
+
+1. ANÁLISIS DE SECCFG (Bootloader Lock State)
+=============================================================================
+
+$ python Tools/seccfg_analyzer.py analyze seccfg.bin
+
+=== Analyzing seccfg file: seccfg.bin ===
+
+File size: 8388608 bytes (0x800000)
+Detected version: V4

+⚠ WARNING: This will modify the partition file!
+           Always backup before flashing to device!
+
+Info: New string 'openmx' is longer than old string 'amxmx'
+      Will attempt to use null terminator space (extend mode)
