Reverse Engineering Mobile Bootloaders, Architecting GSM Tools, and Developing Secure Licensing Systems.
I am a specialized developer focused on Low-Level Programming and Hardware Security. My work involves dissecting mobile firmware, analyzing proprietary protocols, and building tools that interact directly with hardware logic.
- ๐ง Chipset Logic: Deep understanding of Qualcomm EDL (Firehose), MediaTek Brom/Preloader, and Unisoc (SPD) boot chains.
- ๐ Vulnerability Analysis: Researching BootROM exploits, Buffer Overflows, and bypassing security implementations (FRP, MDM, KG).
- โ๏ธ System Internals: Patching Kernels, modifying dtbo/boot.img, and manipulating NVRAM/EFS partitions.
- Overview: A massive multi-brand servicing tool for mobile technicians.
- The Tech: Built with C++/Qt for the frontend and PHP/MySQL for the licensing server.
- Security Features:
- Implemented RSA/AES Encryption for server-client communication.
- Custom Loader Injection: Automating the process of sending signed Firehose loaders to locked Qualcomm devices.
