Engineer Reverse-Engineers Samsung Solar TV Remote with GLM-5.3

Blogger ngxson carried out a full teardown and reverse-engineering of Samsung's solar-powered "smart" TV remote: starting from hardware board analysis, then moving on to BLE communication and firmware flashing mechanisms, assisted throughout by GLM-5.3 (via Hugging Face), ultimately confirming that the remote has secure boot enabled.

Confirmed

The board is neatly divided into two sections: a power management area (voltage regulators, USB charging, AEM30940 solar charging chip) and the main controller RTL8762E.
The MEMS microphone uses the RTL8762E's built-in analog interface directly, with no standalone ADC needed.
Test pads are all present on the board, but log output is locked, blocking the path to directly modifying the remote's firmware.
The TV has already downloaded the OTA firmware package (raw firmware data), which can be flashed to the remote via BLE at any time.
Reverse-engineering confirmed the remote has secure boot enabled.
Fallback plan: use an ESP32 as a BLE man-in-the-middle (remote ↔ ESP32 ↔ TV) to study the communication protocol between remote and TV; ngxson believes it should theoretically work unless hardware-level requirements are involved.

Why it matters

This teardown demonstrates the practical value of AI models (GLM-5.3) in real-world hardware reverse-engineering, and reveals that although Samsung's remote can be firmware-flashed over BLE, protections such as secure boot and locked logging limit third-party modifications — a useful reference for smart home device security research.
