Android Phone Backup & Restore with TWRP - A Comprehensive Guide
Understanding Android Backups with TWRP Recovery
Modifying your Android device through rooting, custom ROM installation, or system-level adjustments carries inherent risks. Prior to undertaking such procedures, it's crucial to familiarize yourself with the methods for backing up and restoring your phone using the TWRP recovery environment.
This guide assumes you have already unlocked your device's bootloader and successfully installed TWRP recovery. If these prerequisites haven't been met, you must complete them before proceeding – this article focuses on utilizing TWRP after it’s been established.
What are Nandroid Backups?
TWRP facilitates the creation of "nandroid" backups. These backups represent comprehensive images of your entire system.
Unlike restoring individual files or applications, nandroid backups are designed to revert your phone to its precise condition at the time the backup was created. This encompasses the Android version, personalized settings like wallpaper, home screen layout, and even unread messages.

Limitations of Nandroid Backups
Nandroid backups are not suitable for partial restorations. If you intend to restore specific components, such as apps, to a new ROM, alternative solutions like Titanium Backup are more appropriate.
TWRP is specifically engineered for complete system backups and restorations, encompassing the entire operating system state.
When to Use Nandroid Backups
- Before flashing a custom ROM.
- Prior to rooting your device.
- Whenever making significant system modifications.
- As a safety net against potential software issues.
Regularly creating nandroid backups provides a reliable recovery point, allowing you to revert to a stable state should any complications arise during system modifications.
Creating a Nandroid Backup Using TWRP
Prior to undertaking any system-level modifications on your Android device—such as gaining root access or installing custom ROMs—it is strongly recommended to create a nandroid backup within the TWRP environment. This safeguard allows for restoration to a functional state should complications arise during the modification process.
The initial step involves booting your device into TWRP recovery mode. The specific method for achieving this varies depending on the phone model. For instance, a simultaneous press of the Power and Volume Down buttons may be required, followed by navigation to "Recovery Mode" using the volume controls. Consult online resources tailored to your particular device to determine the correct procedure.
Upon successful entry into TWRP, you will be presented with the TWRP home screen. Select the "Backup" option to proceed.
A new screen will then appear. Tap the "Name" field located at the top to assign a descriptive name to your backup. Utilizing the current date alongside a brief description of the intended modification is a useful convention—for example:
2016-01-25--pre-rootAlternatively:
2016-01-25--pre-cyanogenmodEnsure that the boxes corresponding to "Boot", "System", and "Data" are checked. Subsequently, swipe across the bottom of the screen to initiate the backup process.
Important Note: Backups can consume a significant amount of storage space. If an error message indicating insufficient space is displayed, it may be necessary to free up storage on either your internal storage or SD card before continuing.
The backup procedure will require several minutes to complete; patience is advised. Once finished, you have the option to return to the main TWRP menu by tapping "Back", or to reboot your device into the Android operating system by selecting "Reboot System".
Should TWRP prompt you regarding rooting your device, it is recommended to choose "Do Not Install". It is preferable to manually flash the most recent version of SuperSU independently, rather than allowing TWRP to handle this step.
Restoring Your Android Device Using a Nandroid Backup in TWRP
Should the need arise to revert to a prior state, the restoration process is straightforward. Initiate a reboot into TWRP recovery mode, then select the “Restore” option located on the main screen.
TWRP will then display a catalog of your previously created backups. Choose the desired backup from the list, and a new screen will appear.
Restoration Procedure
Ensure that all checkboxes are selected to include all partitions in the restoration. Subsequently, swipe the slider to confirm and initiate the restore process.
The restoration procedure will require several minutes to complete. Upon finishing, you can proceed to reboot your device back into the Android operating system.
If prompted regarding rooting during the process, it is recommended to select "Do Not Install".
After returning to Android, your device should be restored to the exact condition it was in at the time the backup was created.
Creating nandroid backups represents a simple yet vital procedure, particularly if you intend to perform any system modifications. It is strongly advised to always create a backup before undertaking any system-level changes.
Should any issues arise during modification, a nandroid backup allows for a seamless restoration, minimizing disruption.
