abootimg-oxide

Android boot image (boot.img) parser written in Rust

unpack_bootimg has been fully reimplemented using this library. Try it by running cargo run --package=unpack_bootimg -- --boot_img <path to boot.img>.

TODO: reimplement mkbootimg

Examples

use std::fs::File;
use abootimg_oxide::{BufReader, Header};

let mut r = BufReader::new(File::open("boot_a.img").unwrap());
let hdr = Header::parse(&mut r).unwrap();
println!("{hdr:#?}");

// Extract the kernel
use std::io::{self, BufWriter, Read, Seek, SeekFrom};

let mut w = BufWriter::new(File::create("boot_a_kernel").unwrap());
let r = r.get_mut();
r.seek(SeekFrom::Start(hdr.kernel_position() as u64))
    .unwrap();
io::copy(&mut r.take(hdr.kernel_size().into()), w.get_mut()).unwrap();
