Custom recovery environments like TWRP (Team Win Recovery Project) are essential tools for Android enthusiasts who want full control over their devices. Whether you’re flashing custom ROMs, making system backups, or gaining root access, TWRP provides a versatile platform. However, if your device isn’t officially supported, you might need to port TWRP manually. This article will guide you through the process step-by-step, ensuring a reliable and functional build.

What is TWRP?
TWRP is an open-source custom recovery tool for Android devices. Unlike stock recovery, it features a touchscreen interface and supports advanced functions such as installing ZIP files, wiping specific partitions, and creating/restoring complete system backups.
Prerequisites
Before starting, make sure you have everything you need:
- A compatible Android device (with an unlocked bootloader)
- Linux or Ubuntu environment (recommended for compiling tools)
- A working copy of the Android source tree or device tree
- Basic knowledge of Android partitions and terminal commands
- USB debugging enabled on your device
Step-by-Step Guide to Porting TWRP
Step 1: Gather Device Information
The first step is collecting essential details about your device:
- SoC platform (e.g., Qualcomm Snapdragon, MediaTek)
- Recovery partition name
- Device codename
- Kernel version and board configuration
You can usually find this information using the terminal or through existing device sources on repositories like GitHub.

Step 2: Download Required Tools and Source Files
Make sure you clone the latest TWRP source code, using the official Git repository:
repo init -u https://github.com/minimal-manifest-twrp/platform_manifest_twrp_aosp.git -b twrp-11 repo sync
Clone or generate the device tree, vendor blobs, and kernel source from your manufacturer or third-party repositories. These files are crucial for informing TWRP how to handle your device’s hardware.
Step 3: Configure Device Tree
If an official device tree is not available, you will need to adapt one from a similar device. Pay special attention to:
- BoardConfig.mk for hardware-specific flags
- recovery.fstab for partition mapping
- Android.mk for compilation structure

Be meticulous here, as incorrect mappings in recovery.fstab can lead to inaccessible storage, failed boots, or even bricking your device.
Step 4: Build TWRP
After correctly configuring the device tree, return to your terminal and execute:
. build/envsetup.sh lunch twrp_devicecodename-eng make recoveryimagename
This will compile a custom recovery image, typically named recovery.img. The compilation process might take some time depending on your system resources.
Step 5: Flash the Recovery
Once built, you can flash the recovery image to your device using fastboot:
fastboot flash recovery recovery.img
Ensure your device is in fastboot mode and check that USB debugging and OEM unlocking were enabled beforehand.
Step 6: Boot and Test
Boot into your new TWRP recovery by executing:
fastboot boot recovery.img
Once inside TWRP, test basic functions like mounting partitions, ADB sideloading, and creating a backup. If there are errors, revisit your recovery.fstab or consider recompiling with adjusted configurations.
Common Issues and Troubleshooting
- Device reboots to system: Recovery not properly flashed. Use fastboot boot to test before flashing.
- Touchscreen not working: Kernel drivers missing from the build. Extract and reconfigure them.
- Unable to mount partitions: Check recovery.fstab and ensure partition names are correct.
Persistence and careful debugging are key at this stage. Always keep a backup of your stock recovery in case you need to revert.
Conclusion
Porting TWRP is a complex yet rewarding task for any Android power user. It demands an understanding of Linux-based systems, Android architecture, and careful attention to device-specific details. By following this step-by-step guide, you’re setting yourself up for success while contributing to the open-source community.
Remember that with great power comes great responsibility—use your custom recovery wisely to enhance your Android experience.
