A comprehensive guide for advanced users to mount all partitions, including Linux partitions, on a rooted Android device using specific tools and apps.

Preparation: - Ensure your device’s battery is fully charged. - Back up all important data, as rooting and partition management can potentially erase everything on your device. - Enable Developer Options and USB Debugging on your device: - Go to Settings > About Phone > Tap 'Build Number' seven times to unlock Developer Options. - Go to Settings > Developer Options > Enable 'USB Debugging'.

Rooting Your Device: - Follow the steps outlined previously to root your device. Ensure you have TWRP recovery installed and Magisk for root access.

Installing Required Tools: - Termux: A powerful terminal emulator for Android. - BusyBox: Provides many Unix utilities and is essential for advanced filesystem operations. - DriveDroid: Useful for managing and mounting various disk images. - StickMount: Helps in mounting USB drives and partitions. - F2FS/NTFS/EXT4 modules: Depending on your needs, you may need specific modules to support additional filesystems.

Installing and Configuring Termux and BusyBox: - Download Termux from the Google Play Store. - Open Termux and install BusyBox by typing: pkg install busybox - Install additional packages needed for mounting partitions: pkg install proot and pkg install util-linux

Mounting Partitions Using StickMount: - Download and install StickMount from the Google Play Store. - Open StickMount, grant it root access. - Connect your external drive to the device using a USB-OTG cable. - StickMount should automatically detect the connected drive and display all partitions. - Use StickMount to mount the partitions you need.

Using DriveDroid for Advanced Partition Management: - Download and install DriveDroid from the Google Play Store. - Open DriveDroid, grant it root access. - Use DriveDroid to create and mount disk images, which can include multiple partitions. - This method provides more flexibility in managing and accessing all partitions.

Manual Mounting Using Termux and BusyBox: - Connect your external drive and identify the device and partition names using: lsblk or fdisk -l within Termux. - Create mount points for each partition you wish to access: - Example: mkdir /storage/ext4_partition1 - Manually mount each partition using BusyBox and appropriate commands: - Example for ext4: busybox mount -t ext4 /dev/block/sdX1 /storage/ext4_partition1 - Replace /dev/block/sdX1 with the actual device name of your partition.

Automating the Mount Process: - To avoid manually mounting partitions each time, you can automate this process by creating a script. - In Termux, create a new script file: nano mount_partitions.sh - Add the mount commands for each partition to this script: sh #!/bin/sh busybox mount -t ext4 /dev/block/sdX1 /storage/ext4_partition1 busybox mount -t ext4 /dev/block/sdX2 /storage/ext4_partition2 # Add more mount commands as needed - Save the script and make it executable: chmod +x mount_partitions.sh - Run the script whenever needed: ./mount_partitions.sh

Verifying Mounted Partitions: - Verify that your partitions are correctly mounted by navigating to the mount points in a file manager or using the df -h command in Termux to see the mounted filesystems and their usage.

Handling Multiple Filesystem Types: - Ensure you have the necessary filesystem modules loaded in your kernel. For ext4, NTFS, and other filesystems, BusyBox usually suffices, but some might require specific kernel modules or additional support in the Android ROM. - If a particular filesystem is not supported, consider converting the partition to a supported filesystem or using tools that provide additional support (e.g., F2FS, exFAT modules).

Summary and Precautions: Rooting your device and managing partitions involves significant risks, including potential data loss and device instability. Always back up your data before proceeding with these steps. Using advanced tools like Termux, BusyBox, StickMount, and DriveDroid allows you to mount and manage multiple partitions on your Android device, providing the flexibility needed to handle complex filesystem setups. Automating the mount process with scripts can simplify your workflow and ensure that your partitions are accessible whenever needed.
