# Partition Manager Tool (PMT)
**Partition Manager Tool** is a fast, reliable, and feature-rich CLI application for **Android** devices that enables advanced partition operations such as backup, flashing, erasing, information retrieval, and more.
This **renovated edition**, written in modern **C++**, is faster, more stable, and more powerful than its previous versions, thanks to optimized multithreading and improved error handling.
PMT is designed for developers, technicians, and Android enthusiasts who need fine-grained control over device partitions via a clean, flexible, and scriptable interface.
---
## Key Features
- **Backup** partitions to files (with permission adjustments for non-root access).
- **Flash** image files directly to partitions.
- **Erase** partitions with zero-byte filling.
- **Retrieve** partition sizes in multiple units.
- **Display** partition info (name, size, logical status) in text or JSON.
- **Resolve** real block device paths and symbolic links.
- **Identify** partition or image file types via magic number checks.
- **Reboot** the device into multiple modes (normal, recovery, etc.).
- **Asynchronous processing** for speed — each partition runs in its own thread.
- **Error isolation** so one failing operation doesnt cancel the rest. For back upping, flashing and erasing.

# Partition Manager Tool (PMT)
**Partition Manager Tool** is a powerful command-line utility for **Android** devices, designed to perform various operations on partitions quickly, reliably, and efficiently.
This is the **renovated version** of PMT, rewritten in C++ for improved performance, stability, and usability compared to its older variant.
It supports **asynchronous operations**, allowing multiple partitions to be processed in parallel, and includes safety measures to prevent a single error from breaking the entire operation batch.
---
## Features
- **Backup** partitions to files (with optional permissions fix for non-root access).
- **Flash** image files directly to partitions.
- **Erase** partitions by filling them with zero bytes.
- **Get** partition sizes in various units.
- **Display** partition information in plain text or JSON format.
- **Retrieve** real paths and symbolic link paths of partitions.
- **Identify** file system or image types by checking magic numbers.
- **Reboot** the device into different modes.
---

## Subcommands
### 1. `backup`
Backup partitions to files. General syntax:
```bash
pmt backup partition(s) [output(s)] [OPTIONS]

**Options:**
- `-b`, `--buffer-size SIZE` → Set buffer size (in bytes) for read/write operations.
- `-O`, `--output-directory DIR` → Specify an output directory for backups.
**Notes:**
- Partition names are separated by commas.
- If custom output names are provided, they must match the number of partitions.
- Automatically adjusts permissions so backup files can be read/written without root.
**Example usages:**\
`pmt backup boot`\
`pmt backup boot boot_backup.img`\
`pmt backup boot,recovery,vendor`\
`pmt backup boot`\
`pmt backup boot,recovery -O /sdcard`\
`pmt backup system,vendor --buffer-size=8192 # '=' is not mandatory`
---
### 2. `flash`
Flash an image or multiple images to partitions. general syntax:
```bash
pmt flash partition(s) image(s) [OPTIONS]
```
**Options:**
- `-b`, `--buffer-size SIZE` → Set buffer size (in bytes).
- `-I`, `--image-directory DIR` → Directory containing image files.
**Notes:**
- Multiple partitions and images are separated by commas.
- **Example usages:**\
`pmt flash boot boot_backup.img`\
`pmt flash boot,recovery /sdcard/backups/boot_backup.img,/sdcard/backups/recovery_backup.img`\
`pmt flash boot boot_backup.img,recovery_backup.img -I /sdcard/backups`\
`pmt flash system,vendor system_backup.img,vendor_backup.img -I /sdcard/backups --buffer-size=8192`
---
### 3. `erase`
Fill partition(s) with zero bytes (like `dd if=/dev/zero of=/dev/block/by-name/<partition>`). General syntax:
```bash
pmt erase partition(s) [OPTIONS]
```
**Options:**
- `-b`, `--buffer-size SIZE` → Set buffer size.
**Example usages (DO NOT USE FOR TRYING!!!):**\
`pmt erase boot`\
`pmt erase nvdata,nvram`\
`pmt erase system,vendor --buffer-size=8192`
---
### 4. `sizeof`
Show the size of partition(s). General syntax:
```bash
pmt sizeof partition(s) [OPTIONS]

**Options:**
- `--as-byte` → Show size in bytes.
- `--as-kilobyte` → Show size in KB.
- `--as-megabyte` → Show size in MB (default).
- `--as-gigabyte` → Show size in GB.
- `--only-size` → Output only the numeric value (no partition name).

```
**Options:**
- `-b`, `--buffer-size SIZE` → Set buffer size.
- `--only-check-android-magics` → Check only Android-related magic numbers.
- `--only-check-filesystem-magic` → Check only file system magic numbers.

### 9. `reboot`
Reboot the device. Default reboot target is normal. General syntax:
```bash
pmt reboot [rebootTarget] [OPTIONS]
```
**Example usages:**\
`pmt reboot`
`pmt reboot recovery`
`pmt reboot download`
## Additional Notes
- **Comma-separated inputs**: All commands (except `reboot`) require multiple inputs to be separated by commas.
- **Asynchronous execution**: For `backup`, `flash`, and `erase`, each partition is processed in a separate thread for maximum speed.
- **Error isolation**: A failure in processing one partition will not cancel the others. Only for `backup`, `flash` and `erase` functions.
- **Automatic diagnostics**: By default, whether a partition is dynamic or regular is determined automatically. With global options, you only specify precision.
## Extra Note: Comma Usage
In **Partition Manager Tool**, whenever you provide **multiple partitions**, **multiple image files**, or **multiple output file names**, they **must** be separated by commas (`,`), without spaces.
**Correct:**\
`pmt backup boot,recovery`\
`pmt flash boot,recovery boot.img,recovery.img`
**Incorrect:**\
`pmt backup boot recovery`\
`pmt flash boot recovery boot.img recovery.img`
The **number of items must match** when providing both input and output lists.
For example, if you specify 3 partitions, you must also provide 3 output file names.
This rule applies to **all commands except `reboot`**, since `reboot` only takes one optional argument.
