What is Boot Image Flasher?
Boot Image Flasher is a shell script developed to simplify the process of flashing boot images on Android devices, supporting both A/B and legacy (non-A/B) devices. Typically, flashing boot images involves using custom recovery or fastboot, which can be complex and time-consuming. This script eliminates the need for those methods, offering a straightforward, efficient, and user-friendly solution.
- Automated and User-Friendly: Simplifies the boot image flashing process with minimal user intervention.
- Broad Device Support: Compatible with any Android device, including both A/B and legacy (non-A/B) partition styles.
- Saves Time and Effort: Reduces the time and complexity involved in flashing boot images using fastboot or custom recoveries, making it accessible for users with varying levels of technical expertise.
- Flexible Usage: Can be used via Termux or as a Magisk module, providing flexibility based on user preferences.
- An Android device with root access.
- To use in Termux,
figletandncurses-utilsneed to be installed if not already available.
-
Open Termux on your Android device.
-
Navigate to the directory where the boot image file is located using
cd. For example:cd /storage/emulated/0/Download -
Copy and paste the following command and hit enter to start running the script:
curl -s https://raw.githubusercontent.com/gitclone-url/Boot-img-flasher/Master/boot-img-flasher.sh -o boot-img-flasher.sh && { command -v tput figlet &>/dev/null || pkg install -y figlet ncurses-utils; } && { which sudo &>/dev/null || pkg install -y tsu; }; clear; sudo bash boot-img-flasher.sh
Note: It may take some time to run for the first time because the script will be downloaded first along with the required tools. Please be patient.
-
Restart your device after the flashing process is complete.
- Download
boot_flasher.zipfrom here. - Extract the archive using an app like ZArchiver.
- After extracting, copy and paste your
boot.imginside the created folder. - Select all files inside the folder and archive them as a zip.
- Install the zip as a Magisk module.
- Restart your device.

Some GSIs (Generic System Images) based on PHH come with prebuilt root access, meaning the su binary is already included in the system. If you are using one of those GSIs and your phone is not actually rooted with Magisk or other root providers, you can just patch the boot image of your phone and then flash the patched boot image using this script, with root permissions granted through the PHH Superuser App. This way, you can easily root using Magisk or other rooting apps just by using your device without needing additional tools, a PC, or any hassles.
Note: For patching the boot image, you can use either Magisk or APatch app.
For information about GSIs, check the FAQ and choose your specific GSI image from here.
