How to Detect Unlocked Bootloader in Android Apps Using AI

Last updated September 3, 2025 by Appdome

This Knowledge Base article describes how to use Appdome’s AI in your CI/CD pipeline to continuously deliver plugins that Detect Unlocked Bootloader in Android apps.

What is an Unlocked Bootloader Attack?

An Unlocked Bootloader Attack targets Android devices with bootloader security disabled, enabling attackers to flash unauthorized firmware, gain root-level access, and bypass OS-level protections. A locked bootloader ensures the device boots only verified, factory-signed software; when unlocked, it removes these safeguards, allowing attackers to modify the boot.img or system.img, install custom ROMs with embedded malware, disable SELinux, Verified Boot, and inject persistent spyware—all undetectable by traditional app-layer defenses. These custom ROMs often mimic the original UI, pass integrity checks, and survive factory resets. Tools like Fastboot and TWRP simplify bootloader unlocking, and AI-driven automation is making mass compromise at scale more feasible.

These attacks are difficult to detect within the app runtime and are increasingly used against low-cost Android models. Protecting against this threat is essential for compliance with standards like PCI DSS, which require controls against unauthorized OS and kernel-level tampering that could compromise app data, sessions, or credentials.

How Appdome Protects Mobile Apps Against Unlocked Bootloader Attacks

Appdome’s dynamic Detect Unlocked Bootloader plugin identifies Android devices with compromised bootloader integrity. It inspects bootloader state by monitoring system flags like ro.boot.flash.locked and ro.boot.verifiedbootstate, and detects unauthorized changes in boot.img, system.img, or custom recovery environments. When threats are detected, the plugin can shut down the session, block app access, or log the event. Mobile developers can use Appdome’s Threat-Events™ to collect real-time telemetry on bootloader status and customize user flows when unlocked bootloaders are present.

Note:

When the app runs on a virtualized environment, the virtualization app mimics the app’s function calls in a way that causes the OS to respond as if the device were unlocked. Because these calls are intercepted and altered, the trusted exchange between the app and the device is broken, leading Detect Unlocked Bootloader to trigger. Running the app directly on the device avoids these detections.

Prerequisites for Using Appdome's Detect Unlocked Bootloader Plugins:

To use Appdome’s mobile app security build system to Detect Unlocked Bootloader , you’ll need:

Appdome account (create a free Appdome account here)
A license for Detect Unlocked Bootloader
Mobile App (.apk or .aab for Android)
Signing Credentials (see Signing Secure Android apps and Signing Secure iOS apps)

How to Implement Detect Unlocked Bootloader in Android Apps Using Appdome

On Appdome, follow these 3 simple steps to create self-defending Android Apps that Detect Unlocked Bootloader without an SDK or gateway:

Designate the Mobile App to be protected.
1. Upload an app via the Appdome Mobile Defense platform GUI or via Appdome’s DEV-API or CI/CD Plugins.
2. Android Formats: .apk or .aab
3. Detect Unlocked Bootloader is compatible with: Java, JS, C++, C#, Kotlin, Flutter, React Native, Unity, Xamarin, Cordova and other Android apps.
Select the defense: Detect Unlocked Bootloader.

Create and name the Fusion Set (security template) that will contain the Detect Unlocked Bootloader feature as shown below:

Figure 1: Fusion Set that will contain the Detect Unlocked Bootloader feature

Follow the steps in Sections 2.2-2.2.2 of this article to add the Detect Unlocked Bootloader feature to your Fusion Set via the Appdome Console.

When you select the Detect Unlocked Bootloader you'll notice that the Fusion Set you created in step 2.1 now bears the icon of the protection category that contains Detect Unlocked Bootloader.

Figure 2: Fusion Set that displays the newly added Detect Unlocked Bootloader protection
Note: Annotating the Fusion Set to identify the protection(s) selected is optional only (not mandatory).

Open the Fusion Set Detail Summary by clicking the “...” symbol on the far-right corner of the Fusion Set. Copy the Fusion Set ID from the Fusion Set Detail Summary (as shown below):

Figure 3: Fusion Set Detail Summary

Follow the instructions below to use the Fusion Set ID inside any standard mobile DevOps or CI/CD toolkit like Bitrise, Jenkins, Travis, Team City, Circle CI or other system:

Refer to the Appdome API Reference Guide for API building instructions.

Look for sample APIs in Appdome’s GitHub Repository.

Add the Detect Unlocked Bootloader feature to your security template.

Navigate to Build > Anti Malware tab > Detect Android Exploit section in the Appdome Console.
Like all other options in ONEShield™, Detect Unlocked Bootloader is turned on by default, as shown below:
Figure 4: Selecting Detect Unlocked Bootloader
Note: The App Compromise Notification contains an easy to follow default remediation path for the mobile app end user. You can customize this message as required to achieve brand specific support, workflow or other messaging.

Toggle On > Detect Unlocked Bootloader.

(a) Choose to monitor this attack vector by checking the Threat Events checkbox associated with Detect Unlocked Bootloader as shown below.

(b) To receive mobile Threat Monitoring, check the ThreatScope™ box as shown below. For more details, see our knowledge base article on ThreatScope™ Mobile XTM.

Figure 4: Selecting Detect Unlocked Bootloader
Note: The Appdome Platform displays the Mobile Operation Systems supported by each defense in real-time. For more details, see our OS Support Policy KB.

Select the Threat-Event™ in-app mobile Threat Defense and Intelligence policy for Detect Unlocked Bootloader:

Threat-Events™ OFF > In-App Defense
If the Threat-Events™ setting is not selected. Appdome will detect and defend user and app by enforcing Detect Unlocked Bootloader.

Threat-Events™ ON > In-App Detection
When this setting is used, Appdome detects if the bootloader has been unlocked on an Android device on which the protected app is running and passes Appdome’s Threat-Event™ attack intelligence to the app’s business logic for processing, enforcement, and user notification. For more information on consuming and using Appdome Threat-Events™ in the app, see section Using Threat-Events™ for Detect Unlocked Bootloader Intelligence and Control in Mobile Apps.

Threat-Events™ ON > In-App Defense
When this setting is used, Appdome detects and defends against Unlocked Bootloader (same as Appdome Enforce) and passes Appdome’s Threat-Event™ attack intelligence to the app’s business logic for processing. For more information on consuming and using Appdome Threat-Events™ in the app, see section Using Threat-Events™ for Detect Unlocked Bootloader Intelligence and Control in Mobile Apps.

Configure the User Experience Options for Detect Unlocked Bootloader:
With Threat-Events™ OFF, Appdome provides several user experience options for mobile brands and developers.

App Compromise Notification: Customize the pop-up or toast Appdome uses to notify the user when a threat is present while using the protected mobile app.

Short message Option. This is available for mobile devices that allow a banner notification for security events.

Localized Message Option. Allows Appdome users to support global languages in security notifications.

Figure 5: Default User Experience Options for Appdome’s Unlocked Bootloader

Detect Unlocked Bootloader Threat Code™. Appdome uses AI to generate a unique code each time Detect Unlocked Bootloader is triggered by an active threat on the mobile device. Use the code in Appdome Threat Resolution Center™ to help end users identify, find and resolve active threats on the personal mobile devices.

Initiate the build command either by clicking Build My App at the bottom of the Build Workflow (shown in Figure 4) or via your CI/CD as described in Section 2.1.4.

Congratulations! The Detect Unlocked Bootloader protection is now added to the mobile app

Certify the Detect Unlocked Bootloader feature in Android Apps

After building Detect Unlocked Bootloader, Appdome generates a Certified Secure™ certificate to guarantee that the Detect Unlocked Bootloader protection has been added and is protecting the app. To verify that the Detect Unlocked Bootloader protection has been added to the mobile app, locate the protection in the Certified Secure™ certificate as shown below:

Figure 6: Certified Secure™ certificate

Each Certified Secure™ certificate provides DevOps and DevSecOps organizations the entire workflow summary, audit trail of each build, and proof of protection that Detect Unlocked Bootloader has been added to each Android app. Certified Secure provides instant and in-line DevSecOps compliance certification that Detect Unlocked Bootloader and other mobile app security features are in each build of the mobile app.

Using Threat-Events™ for Unlocked Bootloader Intelligence and Control in Android Apps

Appdome Threat-Events™ provides consumable in-app mobile app attack intelligence and defense control when Unlocked Bootloader is detected.
