# Settings

This guide shows how to configure paths for system tools, ADB key management, optional Python setup, even export/import utilities for saving your configurations.

***

## Configuring System Paths

Before using most features in Cellhasher Control, your system paths must be set correctly. These paths tell the software where to find required executables like ADB, Fastboot, and Scrcpy.

### Download and Set Paths

If you don’t already have these installed or don’t know where to find them:

1. Click the **Download** button next to each tool. Cellhasher will automatically fetch and install the latest version for your system.
2. For the applicable downloads, extract the `.zip` file.
3. Set the path of the `.exe` for each line.

> **ℹ️ Note:** Redownload the latest versions occasionally for best performance and compatibility

| Tool                            | Description                                         | Example Path                                                             |
| ------------------------------- | --------------------------------------------------- | ------------------------------------------------------------------------ |
| **ADB**                         | Core tool used to communicate with Android devices. | `C:\Users\<username>\platform-tools\adb.exe`                             |
| **Fastboot**                    | Used for bootloader and flashing operations.        | `C:\Users\<username>\platform-tools\fastboot.exe`                        |
| **Heimdall (Optional)**         | Used for Samsung flashing.                          | `C:\platform-tools\heimdall.exe`                                         |
| **Scrcpy**                      | Required for screen mirroring and control.          | `C:\Users\<username>\Downloads\scrcpy-win64-v3.3.3\scrcpy.exe`           |
| **Python (Highly recommended)** | Enables scripting, automation, and custom flows.    | `C:\Users\<username>\AppData\Local\Programs\Python\Python313\python.exe` |

### API Keys (AI Integration)

In upcoming releases, **Cellhasher AI** will introduce advanced features for:

* Device diagnostics
* Automated optimization
* Predictive management

You’ll be able to add your OpenAI, Mistral, or other API keys in this section to enable AI-based control, automation, and natural-language scripting.

***

### ADB Key Management

This is where you manage the key files that allow ADB to control your phones. Each phone has a key, stored in both `adbkey` and `adbkey.pub` files. If you have ADB Keys from another computer or source, you can import them here.

> ✅ Cellhasher purcahses with phones pre-installed come with ADB Authoization Keys. Import the key files here.

Check [enabling-usb-and-wireless-debugging.md](/docs/additional-docs/enabling-usb-and-wireless-debugging.md) for more information. Your device may already be included in the current key set if you do not see an authorization prompt.

### Reset ADB

Click the red “Reset ADB” button at the top right if devices fail to appear or ADB gets stuck.

### How to Find Your ADB Key Files

If you’d like to import your existing **ADB keys** into CellHasher Control (to avoid physically approving devices again), you can find them in your system’s hidden **`.android`** folder.

Here’s where to look:

| **OS**  | **Path to ADB Keys**                |
| ------- | ----------------------------------- |
| Windows | `C:\Users\<YourUsername>\.android\` |
| MacOS   | `/Users/<YourUsername>/.android/`   |
| Linux   | `/home/<YourUsername>/.android/`    |

Inside that folder, you’ll find two key files:

```
adbkey
adbkey.pub
```

#### To Import in Cellhasher Control:

1. Open **Settings → ADB Keys**.
2. Click **Import ADB Key**.
3. Select both `adbkey` and `adbkey.pub`.
4. Restart **Cellhasher Control** to apply the keys.

> 💡 **Tip:** If you don’t see the `.android` folder, enable **Show Hidden Files** in your system file explorer.
