# 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.

### 9. `reboot`

|
|
|
## 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.
