How to Install and Manage LKM Kernel Module on Android Using Termux

If you’re looking to install and manage a Loadable Kernel Module (LKM) on your Android device, Termux is a powerful tool that can help you achieve this. Below is a step-by-step guide on how to set it up and get started.

Prerequisites

Android Device: Ensure your device is rooted and running a compatible kernel.
Termux: A terminal emulator for Android that allows you to run a Linux environment on your device.
LKM Kernel Module: The module you want to install, provided in a .deb package.

Step 1: Install Termux from F-Droid

The first step is to install Termux. It’s recommended to download Termux from F-Droid because the Play Store version may not work correctly due to recent changes in Google’s policies.

Visit the F-Droid website.
Search for “Termux” and install it.

Step 2: Grant Storage Permissions

After installing Termux, you need to grant it storage permissions to access your device’s file system.

Open Termux.
Run the following command to set up storage:
```
termux-setup-storage
```
This command will request storage permissions and create a storage directory in your Termux home folder.

Step 3: Update Termux Packages

Before installing any new packages, it’s crucial to update the package lists and upgrade existing packages to ensure compatibility and security.

Update the package list:
```
pkg update
```
Upgrade all installed packages:
```
pkg upgrade
```

Step 4: Install the LKM Kernel Module

Once the environment is set up, you can proceed to install the LKM Kernel Module.

Navigate to the directory where the .deb file is stored. Typically, it’s in the Download folder:
```
cd /storage/emulated/0/Download/
```
Install the LKM Kernel Module using the following command:
```
apt install ./LKM-kernel.deb
```
This command installs the .deb package, which contains the kernel module.

Step 5: Run the LKM Kernel Module

After installation, you can load the kernel module into the kernel.

Simply run the following command to load the module:
```
lkm
```
This command executes the module’s functionality. Depending on what the LKM does, you might see different outputs or changes in your system.

Uninstalling the LKM Kernel Module

If you ever need to remove the LKM Kernel Module, you can easily uninstall it using the following steps:

Run the following command to uninstall the module:
```
apt remove lkm-kernel
```
This command will remove the kernel module and its associated files from your system.

Conclusion

Managing kernel modules on Android can be a powerful way to extend your device’s capabilities. Using Termux and the steps outlined above, you can easily install, manage, and uninstall Loadable Kernel Modules (LKMs) on your Android device. Always ensure that the modules you install are compatible with your kernel version and come from a trusted source to avoid potential issues.
