Flash SPI Tool: Flashing BIOS and SPI EEPROMs from Android with flashrom

Flash SPI Tool: Native Android GUI for BIOS and EEPROM Flashing (flashrom Engine)

When repairing computer motherboards, laptops, or game consoles with corrupted BIOS / UEFI firmware, technicians typically rely on an external programmer (like the CH341A) connected to a desktop computer.

Flash SPI Tool brings the full power of the industry-standard flashrom engine to Android devices over USB-OTG, eliminating the need for a PC during bench repairs.

🔬 How It Works

Flash SPI Tool bridges the gap between low-level hardware flashing and Android's sandboxed environment:

• Custom Native flashrom Engine: Compiled for arm64-v8a with 16KB page-size alignment for compatibility with modern Android versions (Android 7.0 up to Android 17).
• Zero-OOM C++ Transport Layer: Implemented via a high-performance native USB bridge (usb_bridge.cpp) communicating through Android USB Host APIs without root permissions.
• Supported Memories: SPI Flash (25-series, W25Qxx), I2C EEPROMs (24-series), and LPC/FWH chips using SOIC8 test clips or DIP sockets.
