SharpFastboot (FirmwareKit.Comm.Fastboot)

A high-performance C# implementation of the Android Fastboot protocol, aligned with the latest AOSP (Android Open Source Project) logic. Designed for firmware flashing, device management, and automation.

Features

• AOSP Aligned: Core logic (Download, Erase, Flash, etc.) strictly follows the official Google fastboot implementation.
• Multi-Transport Support:
  • USB (Windows WinUSB & Legacy support)
  • Fastboot over TCP
  • Fastboot over UDP
• Multi-Targeting: Supports .NET Standard 2.0/2.1, .NET 6.0, .NET 8.0, and above.
• Modern C# 12 Syntax: Optimized for performance and readability while maintaining backward compatibility.

Installation

Install via NuGet:

dotnet add package FirmwareKit.Comm.Fastboot

Quick Start

1. Initialize Fastboot Utility

using FirmwareKit.Comm.Fastboot;
using FirmwareKit.Comm.Fastboot.Usb.Windows;

// Initialize USB Transport (Example for Windows WinUSB)
var transport = new WinUSBDevice { DevicePath = "..." }; 
var fastboot = new FastbootUtil(transport);

// Get variable
var version = fastboot.GetVar("version");
Console.WriteLine($"Fastboot Version: {version}");

2. Flashing a Partition

// Simple flash command
fastboot.Flash("boot", "path/to/boot.img");

// Alignment with AOSP handshaking logic ensure stability
fastboot.Erase("system");
