Performance varies based on storage speed, compression format, and CPU SIMD capability. ```text Throughput Example (3GB system partition) ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ otaripper (AVX-512) ████████████ 2.8 GB/s otaripper (AVX2) ████████ 1.9 GB/s payload-dumper-go ████ 1.0 GB/s payload_dumper ██ 0.4 GB/s ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ ``` -------------------------------- ### Install Otaripper via AUR Source: https://github.com/syedinsaf/otaripper/blob/main/README.md Instructions for installing otaripper on Arch Linux using the AUR helpers paru and yay. It provides options for building from source or using a prebuilt binary. ```bash paru -S otaripper # build from source (recommended) paru -S otaripper-bin # prebuilt glibc binary yay -S otaripper yay -S otaripper-bin ``` -------------------------------- ### Build Otaripper from Source (Linux/macOS) Source: https://context7.com/syedinsaf/otaripper/llms.txt Clone the repository and use Cargo to build a standard portable release binary. For maximum local performance, use the provided helper scripts (`build.sh`) to create a CPU-native build, which should not be redistributed. ```bash # Standard portable release build git clone https://github.com/syedinsaf/otaripper.git cd otaripper cargo build --release # Binary: target/release/otaripper (Linux/macOS) # target/release/otaripper.exe (Windows) # CPU-native build via helper scripts (Linux/macOS) chmod +x build.sh && ./build.sh # Output: ./otaripper-native/otaripper ``` -------------------------------- ### Build Otaripper from Source (Windows PowerShell) Source: https://context7.com/syedinsaf/otaripper/llms.txt Use PowerShell to build a CPU-native version of Otaripper for Windows. Ensure the execution policy is set appropriately before running the build script. ```powershell # CPU-native build on Windows (PowerShell) Set-ExecutionPolicy -Scope Process -ExecutionPolicy Bypass .uild.ps1 # Output: .\otaripper-native\otaripper.exe ``` -------------------------------- ### otaripper vs. Traditional File I/O Source: https://github.com/syedinsaf/otaripper/blob/main/TECHNICAL.md Illustrates the difference between traditional buffered file reading and otaripper's zero-copy memory mapping approach. otaripper's method bypasses intermediate kernel buffers for direct process access. ```text Traditional: File → read() → Kernel Buffer → User Buffer → Copy → Process otaripper: File → mmap() → Direct Process Access ``` -------------------------------- ### List Partitions Source: https://github.com/syedinsaf/otaripper/blob/main/README.md Command to list all available partitions within an OTA zip file without extracting them. Useful for inspecting the contents before extraction. ```bash otaripper -l ota.zip ``` -------------------------------- ### Build Otaripper from Source Source: https://github.com/syedinsaf/otaripper/blob/main/README.md Steps to clone the otaripper repository and build the release binary using Cargo. Requires Rust 1.95.0 or newer, Git, and a C compiler. ```bash git clone https://github.com/syedinsaf/otaripper.git cd otaripper cargo build --release ``` -------------------------------- ### Extract All Partitions Source: https://github.com/syedinsaf/otaripper/blob/main/README.md Basic command to extract all partitions from an OTA zip file. Ensure the zip file is in the current directory or provide the full path. ```bash otaripper ota.zip ``` -------------------------------- ### Display Performance Statistics with --stats Source: https://context7.com/syedinsaf/otaripper/llms.txt Print per-partition throughput (bytes extracted and time elapsed) and a total wall-clock summary after extraction. Useful for profiling storage and decompression bottlenecks across different hardware configurations. ```bash otaripper update.zip --stats # Output: # Extraction statistics: # - boot: 67.11 MiB in 24 ms (2.80 GB/s) # - system: 2.80 GiB in 1103 ms (2.54 GB/s) # - vendor: 1.10 GiB in 412 ms (2.67 GB/s) # Total: 8.42 GiB in 3218 ms (2.62 GB/s) ``` -------------------------------- ### Perform Sanity Checks with --sanity Source: https://context7.com/syedinsaf/otaripper/llms.txt After extraction, run a lightweight all-zero check on every output image using SIMD acceleration. This catches obviously invalid images such as a partition filled entirely with zero bytes, which would indicate a decompression failure or a corrupted OTA. ```bash otaripper update.zip --sanity # If an image is all-zero: # Critical error: Sanity check failed for 'system' # ❌ Extraction failed due to errors (see above). All partial files have been cleaned up. ``` -------------------------------- ### List Partitions in OTA Package Source: https://context7.com/syedinsaf/otaripper/llms.txt Lists all partitions contained within an OTA package without extracting them. It displays the target size and type (Full or Delta) for each partition. Incremental partitions are identified and will not be extracted. ```bash otaripper -l update.zip # Expected output: # Partition Size Type # ---------------------------------------------- # boot 67.11 MiB Full # init_boot 8.00 MiB Full # system 2.80 GiB Full # system_ext 512.00 MiB Full # vendor 1.10 GiB Full # vendor_boot 67.11 MiB Full # ---------------------------------------------- # Total Partitions: 24 ``` -------------------------------- ### Print Hashes Source: https://github.com/syedinsaf/otaripper/blob/main/README.md Command to print the SHA-256 hashes of the partitions within the OTA zip file. This can be used for verification purposes. ```bash otaripper ota.zip --print-hash ``` -------------------------------- ### Release Profile Configuration Source: https://github.com/syedinsaf/otaripper/blob/main/TECHNICAL.md Configure Rust release builds for optimal performance by enabling Link Time Optimization (LTO) and reducing codegen units. Consider `target-cpu=native` for local builds. ```toml [profile.release] lto = "fat" codegen-units = 1 ``` -------------------------------- ### Print SHA-256 Hashes with --print-hash Source: https://context7.com/syedinsaf/otaripper/llms.txt Compute and print the SHA-256 digest of every extracted partition image after extraction completes. If the manifest already contains the hash and verification passed, the digest is reused; otherwise, a single linear pass over the output image is performed. ```bash otaripper update.zip --print-hash # Output after extraction: # Partition hashes (SHA-256): # boot: sha256=3a7bd3e2360a3d29eea436fcfb7e44c735d117c42d1c1835420b6b9942dd4f1b # init_boot: sha256=f1e2d3... # system: sha256=9d1f7b... ``` -------------------------------- ### Scan ARB Metadata with 'arbscan' / 'arb' Source: https://context7.com/syedinsaf/otaripper/llms.txt Analyze Qualcomm Anti-Rollback (ARB) metadata from a bootloader image or directly from a full OTA package. Outputs Major/Minor version and ARB index; optionally saves a JSON record. When given an OTA package, the tool silently extracts `xbl_config.img` and cleans up automatically. ```bash # Scan a raw bootloader image otaripper arbscan xbl_config.img # [arbscan] Analyzing: xbl_config.img # # OEM Metadata # ──────────── # Major Version : 3 # Minor Version : 1 # ARB Index : 5 # # Write JSON output? [y/N]: # Scan directly from OTA zip (extracts xbl_config.img automatically) otaripper arb update.zip # Suppress JSON prompt (non-interactive / scripted use) otaripper arbscan -n xbl_config.img # JSON output file (when opted in): xbl_config_arb.json # { # "device_model": "Xiaomi 14 Pro", # "update_label": "HyperOS 2.0.1", # "image": "xbl_config.img", # "major": 3, # "minor": 1, # "arb": 5, # "hash_offset": 4096, # "hash_size": 8192 # } ``` -------------------------------- ### Extract All Partitions from OTA Package Source: https://context7.com/syedinsaf/otaripper/llms.txt Extracts all partitions from a full OTA zip or a raw payload.bin file. By default, it performs SHA-256 verification on each extracted image and saves them into a timestamped output folder. ```bash otaripper update.zip # Output: ./extracted_2026-05-07_14-30-00/boot.img, system.img, vendor.img, ... ``` ```bash otaripper payload.bin ``` ```bash # Expected output: # Extraction in progress — do NOT close this window! Use Ctrl+C to cancel safely. # Processing 24 partitions using 16 threads... # boot [=========================>] 100% # system [=========================>] 100% # vendor [=========================>] 100% # ... # Extraction completed successfully! # Output directory: ./extracted_2026-05-07_14-30-00 # Total extracted size: 8.42 GiB ``` -------------------------------- ### Extract Selected Partitions Source: https://github.com/syedinsaf/otaripper/blob/main/README.md Command to extract only specific partitions from an OTA zip file. Partitions are specified as a comma-separated list. ```bash otaripper ota.zip -p boot,vendor_boot,init_boot ``` -------------------------------- ### Debug CPU Detection Command Source: https://github.com/syedinsaf/otaripper/blob/main/TECHNICAL.md Use this command to enable debug output for CPU detection and SIMD execution path selection. ```bash OTARIPPER_DEBUG_CPU=1 ./otaripper ota.zip ``` -------------------------------- ### Analyze Qualcomm Bootloader ARB Metadata Source: https://github.com/syedinsaf/otaripper/blob/main/README.md Analyzes Qualcomm bootloader Anti-Rollback (ARB) metadata. Accepts various image formats including .img, .bin, and .zip. ```bash otaripper arb update.zip or otaripper arb xbl_config.img ``` -------------------------------- ### Enable Otaripper Debug CPU Output Source: https://context7.com/syedinsaf/otaripper/llms.txt Set the OTARIPPER_DEBUG_CPU environment variable to 1 before running otaripper to print detected CPU SIMD capabilities and the selected execution path to stderr. This is useful for verifying SIMD utilization or diagnosing performance issues. ```bash OTARIPPER_DEBUG_CPU=1 otaripper update.zip # Additional stderr output at startup: # CPU Feature Detection: # AVX512F: true # AVX512BW: true # AVX2: true # SSE2: true # Selected: Avx512 ``` -------------------------------- ### Skip Verification with --no-verify Source: https://context7.com/syedinsaf/otaripper/llms.txt Disable SHA-256 input hash checks and all output verification. Intended only for trusted sources where speed is more important than integrity guarantees. Mutually exclusive with --strict. ```bash otaripper update.zip --no-verify # Skip verification and suppress folder auto-open otaripper update.zip --no-verify -n ``` -------------------------------- ### Strict Verification Mode Source: https://context7.com/syedinsaf/otaripper/llms.txt Enforces SHA-256 hashing for every partition and data operation in the manifest. Extraction aborts if any hash is missing, ensuring maximum integrity. This mode can be combined with `--print-hash` to display the hashes of extracted partitions. ```bash otaripper update.zip --strict # If a partition hash is missing from the manifest: # ERROR: strict mode: missing partition hash for 'system_dlkm' # Combine with hash printing otaripper update.zip --strict --print-hash # Partition hashes (SHA-256): # boot: sha256=3a7bd3e2360a3d29eea436fcfb7e44c735d117c42d1c1835420b6b9942dd4f1b # system: sha256=9d1f7b... ``` -------------------------------- ### Memory Layout for Parallel Extraction Source: https://github.com/syedinsaf/otaripper/blob/main/TECHNICAL.md Visualizes the memory layout during parallel extraction in otaripper. It shows the read-only input payload, worker threads operating on disjoint extents, and the write-only output partition. ```text ┌─────────────────────────────────────┐ │ Input: payload.bin (read-only mmap) │ │ - Shared across all workers │ │ - OS-managed paging │ └─────────────────────────────────────┘ ↓ ┌─────────────────────────────────────┐ │ Worker Threads (N parallel) │ │ - Disjoint extents only │ │ - No locks in hot path │ │ - Thread-local decompression │ │ - 1 MiB thread-local buffer pool │ └─────────────────────────────────────┘ ↓ ┌─────────────────────────────────────┐ │ Output: partition.img (write mmap) │ │ - Pre-sized to final length │ │ - No overlapping writes │ └─────────────────────────────────────┘ ``` -------------------------------- ### Selective Partition Extraction Source: https://context7.com/syedinsaf/otaripper/llms.txt Extracts only a specified subset of partitions using a comma-separated list of partition names. Partition names must match those listed by the `-l` command and exclude the `.img` extension. Providing unrecognized partition names will result in an immediate error. ```bash # Extract only the boot-related partitions otaripper update.zip -p boot,init_boot,vendor_boot ``` ```bash # Extract a single partition otaripper update.zip -p system ``` ```bash # Error case — typo in partition name otaripper update.zip -p boo # ERROR: partition "boo" not found in manifest ``` -------------------------------- ### Specify Output Directory Source: https://context7.com/syedinsaf/otaripper/llms.txt Redirects the timestamped extraction folder to a specified parent directory. This is useful for extracting files to a different drive or a designated workspace. ```bash # Extract to a specific directory otaripper update.zip -o /mnt/nvme/ota-work # Output will be at: /mnt/nvme/ota-work/extracted_2026-05-07_14-30-00/ # Combine with selective extraction otaripper update.zip -p system,vendor -o /tmp/partitions ``` -------------------------------- ### Strict Verification Source: https://github.com/syedinsaf/otaripper/blob/main/README.md Enforces strict verification of partition hashes against the manifest. This ensures data integrity but may fail if the manifest is incorrect or the zip is corrupted. ```bash otaripper ota.zip --strict ``` -------------------------------- ### Control Thread Count with -t Source: https://context7.com/syedinsaf/otaripper/llms.txt Override the default automatic thread count. Valid range is 1–256; passing 0 restores auto-detection. Performance gains taper beyond ~16 threads on most consumer NVMe drives. HDDs benefit less from high parallelism than SSDs. ```bash # Use 8 threads otaripper update.zip -t 8 # Using 8 worker thread(s) # Force single-threaded extraction otaripper update.zip -t 1 # Out of range — produces a clear error otaripper update.zip -t 512 # ERROR: Thread count 512 is out of range. # Valid range: 1–256 # Hint: Use 0 or leave -t unset to auto-detect (recommended). ``` -------------------------------- ### Parse Binary Payload with Rust Source: https://context7.com/syedinsaf/otaripper/llms.txt Use the `Payload::parse` function to parse a byte slice of a `payload.bin` file. It validates the file format and returns zero-copy slices for the manifest and data. This function provides human-friendly error messages for non-OTA files. ```rust use otaripper::payload::Payload; use std::fs; fn main() -> anyhow::Result<()> { let bytes = fs::read("payload.bin")?; let payload = Payload::parse(&bytes)?; println!("Format version : {}", payload.file_format_version); println!("Manifest size : {} bytes", payload.manifest_size); println!("Data region : {} bytes", payload.data.len()); // manifest is a zero-copy &[u8] slice ready for prost::Message::decode() // payload.data contains the raw compressed partition data blocks // Error cases with friendly messages: // - Windows EXE: "💀 Bro… you just fed me a WINDOWS .EXE." // - ZIP w/o payload: "📦 This is a ZIP archive… which is GREAT… except it does NOT contain a valid payload.bin" // - JPEG/PNG: "🖼️ Not you trying to extract… a JPEG 💀" // - Unknown: "❌ This file isn't a recognized Android update." Ok(()) } ``` -------------------------------- ### Runtime SIMD Detection with Rust Source: https://context7.com/syedinsaf/otaripper/llms.txt Utilize `CpuSimd::get()` for runtime SIMD detection, which is cached globally. This function detects the best available x86_64 SIMD capability (AVX-512 → AVX2 → SSE2 → scalar) and falls back to scalar copies on non-x86_64 targets. It's used for accelerated memory operations like `simd_copy_large` and `is_all_zero_with_simd`. ```rust use otaripper::cmd::simd::{CpuSimd, simd_copy_large, is_all_zero_with_simd}; fn main() { let simd = CpuSimd::get(); // Detected once, cached globally // SIMD-accelerated bulk copy (uses AVX-512/AVX2/SSE2 non-temporal stores for >= 1 MiB) let src = vec![0xABu8; 8 * 1024 * 1024]; // 8 MiB let mut dst = vec![0u8; src.len()]; simd_copy_large(simd, &src, &mut dst); assert_eq!(src, dst); // SIMD-accelerated all-zero detection (used by --sanity) let zeroes = vec![0u8; 4 * 1024 * 1024]; let nonzero = vec![1u8; 4 * 1024 * 1024]; assert!(is_all_zero_with_simd(simd, &zeroes)); assert!(!is_all_zero_with_simd(simd, &nonzero)); } ``` -------------------------------- ### Disable Auto-Open with -n / --no-open Source: https://context7.com/syedinsaf/otaripper/llms.txt By default otaripper opens the extraction folder in the system file manager upon success. Pass -n to suppress this behavior, which is useful in scripts and automated pipelines. ```bash # Script-friendly extraction — no GUI popup otaripper update.zip -n -o /output/path # Combine with stats for CI/CD logging otaripper update.zip -n --stats 2>&1 | tee extraction.log ``` -------------------------------- ### Clean Extracted Folders with 'clean' Source: https://context7.com/syedinsaf/otaripper/llms.txt Remove all `extracted_*` directories produced by previous runs. Operates on the current directory by default, or on a user-specified path. Refuses to operate on filesystem roots. Prompts for confirmation before deleting. ```bash # Remove all extracted_* folders in the current directory otaripper clean # Clean a specific directory otaripper clean -o /mnt/nvme/ota-work # Expected interaction: # Scanning for extracted folders in: # /mnt/nvme/ota-work # # The following folders will be removed: # /mnt/nvme/ota-work/extracted_2026-05-07_14-30-00 # /mnt/nvme/ota-work/extracted_2026-05-06_09-10-22 # # Proceed? [Y/n]: y # Removed /mnt/nvme/ota-work/extracted_2026-05-07_14-30-00 # Removed /mnt/nvme/ota-work/extracted_2026-05-06_09-10-22 # Cleanup complete. ``` -------------------------------- ### Clean Specific Directory Source: https://github.com/syedinsaf/otaripper/blob/main/README.md Cleans up extracted folders within a specified output directory. Use this to manage extracted files in a custom location. ```bash otaripper clean -o /path/to/output ``` -------------------------------- ### Disable Automatic Folder Opening Source: https://github.com/syedinsaf/otaripper/blob/main/README.md Prevents otaripper from automatically opening the output directory after extraction. Use this if you prefer manual control over opening the extracted files. ```bash otaripper ota.zip -n ``` -------------------------------- ### Remove Previously Extracted Folders Source: https://github.com/syedinsaf/otaripper/blob/main/README.md Cleans up previously extracted folders by removing directories matching the pattern `extracted_*`. This command is designed to be safe and refuses to operate on filesystem roots. ```bash otaripper clean ``` === COMPLETE CONTENT === This response contains all available snippets from this library.
