Unlocking the bootloader on the Asus ZenFone Max Pro M1 typically requires a PC, especially for the reliable "unofficial" method using batch files like unlock.bat. While an official Unlock Tool APK once allowed users to unlock directly from the phone without a computer, this service has been largely discontinued and is now highly unreliable. Status of the "No PC" Method (Official APK)
The official Asus Unlock Tool (e.g., UnlockTool_9.1.0.3_180621_fulldpi_signed_ZB601KL.apk) was the only way to unlock without a computer. However, the following issues make it difficult to use today:
Server Discontinuation: Asus officially discontinued the bootloader unlock tool service in late 2023. Since the APK requires an active connection to Asus servers to authorize the unlock, it frequently fails or crashes.
Model Specificity: The APK was designed for specific firmware versions; using it on newer Android versions (like Android 10 beta) often results in crashes or errors.
Privacy & Warranty: Using the official tool permanently records your device's IMEI as "unlocked" in Asus's database, which officially voids your warranty. Why the PC Method is Recommended
Most successful unlocks for this device now rely on the unofficial PC method, which uses a specialized unlock.bat file to bypass the need for Asus's online authentication.
Advantages: It allows you to unlock the bootloader without reporting it to Asus, making it possible to relock the device later for warranty purposes.
Requirements: You need a Windows PC with ASUS drivers and the unlock.rar package. Critical Precautions Regardless of the method used, keep these risks in mind:
Data Loss: Unlocking the bootloader erases all data on the phone. Always perform a full backup before starting.
Bricking Risk: Using an unlock tool designed for a different Android version or model can permanently damage (brick) your device.

Unlocking the bootloader on the Asus Zenfone Max Pro M1 (ZB601KL/ZB602KL) without a PC was originally possible using an official Asus APK. However, recent reports from the Asus ZenTalk community indicate that Asus has largely deactivated the servers required for this tool to function, making it unreliable or completely non-functional for many users. Method: Using the Official Unlock Tool APK
If the official servers are active for your specific region or firmware, you can attempt to unlock directly on the device. Prerequisites: Back up all data; unlocking wipes the device.
Enable "Unknown Sources" in your security settings to install third-party APKs. Ensure a stable internet connection. Step-by-Step:
Download: Search for and download the UnlockTool_9.1.0.3_180621_fulldpi_signed_ZB601KL.apk from reputable sources like the XDA Developers forum or GitHub. Install: Open the APK and install it on your phone. Run: Launch the app and read the terms and conditions. Unlock: Tap the button to "Unlock your device."
Reboot: If successful, the device will automatically reboot and perform a factory reset. Current Critical Limitations
Server Shutdown: Asus has officially ended updates and maintenance for the Max Pro M1. This includes the authentication servers needed for the APK to work. If you receive an error like "Internet connection failed" despite having Wi-Fi, the server is likely dead.
Missing OEM Toggle: Users frequently find that the "OEM Unlocking" option is missing from Developer Settings in newer stock firmware, which blocks the tool.
No Unofficial "No-PC" Alternative: There is currently no stable "no-PC" unofficial method (like a one-click root exploit) for this device. Almost all reliable current methods require a PC to run Fastboot commands. Recommended Alternative (Requires PC)
Because the APK method is now unreliable, most users use a small "Unlock.bat" file on a computer while the phone is in Fastboot Mode (Volume Up + Power). This method is "unofficial" but highly effective and does not rely on Asus's defunct servers.
Important Disclaimer:
Before attempting this, your phone must have one of the following:
Given these constraints, the only genuine "no PC" method for a virgin, locked device involves using Terminal Emulator and exploiting known vulnerabilities from specific old firmware versions.
| Method | Feasibility | Risk Level | |--------|-------------|------------| | Official ASUS Unlock APK | ❌ Dead (server offline) | Low | | Terminal + Fastboot binary | ❌ Needs root to reboot bootloader | High | | Bugjaeger with second phone | ✅ Works reliably | Medium | | Manual partition edit | ⚠️ Only for experts | Extreme |
Conclusion: You cannot unlock the Zenfone Max Pro M1 bootloader completely without any external computing device unless you already have root or a second Android phone. The Bugjaeger + OTG method is your best bet and is considered "without a PC" by most definitions.
To ensure the bootloader is truly unlocked without connecting to a PC:
Visit a friend with a laptop, spend 3 minutes running fastboot oem unlock, and be done. It saves hours of frustration. But if you absolutely cannot access any computer, the dual-phone OTG method above is your only proven path.
This guide is based on community research from XDA Developers (thread 3826534) and real-world testing on firmware version WW-16.2017.2004.083. Your mileage may vary. Always backup your data first. Unlocking the bootloader on the Asus Zenfone Max
Unlocking the bootloader on your Asus Zenfone Max Pro M1 allows you to install custom ROMs, recovery environments like TWRP, and gain root access. While the official method usually involves a computer and Fastboot commands, many users prefer a mobile-only approach.
It is important to note that unlocking your bootloader will factory reset your device and void your warranty. Always back up your data before proceeding. Prerequisites Before You Begin
Before attempting the unlock process, ensure your device meets these requirements:
Battery Level: At least 60% to prevent shutdown during the process.
Data Backup: Move photos, contacts, and files to cloud storage or an SD card.
Official Unlock Tool: You will need the Asus Unlock Device Tool APK (available on the Asus support website).
Unknown Sources: Enable "Install from Unknown Sources" in your security settings. Step 1: Download the Official Unlock Tool
Asus provides a dedicated application for unlocking the bootloader. Since you are not using a PC, you will download this directly to your phone. Open your mobile browser. Search for the Asus Zenfone Max Pro M1 Support Page. Navigate to the Driver & Tools section. Select Android as the OS. Find the Unlock Device App and download the APK file. Step 2: Install and Configure the App
Once the download is complete, you need to install the application. Locate the APK in your Downloads folder. Tap the file to install it. Open the Unlock Device app. Read and agree to the Terms and Conditions.
Check the box stating you understand the risks of unlocking. Step 3: Executing the Unlock Process
This is the final stage where the software modifies your device's firmware settings.
Inside the app, tap the button labeled "Press to unlock your device."
The phone may prompt you for your screen lock PIN or password. Your Zenfone Max Pro M1 will automatically reboot.
A warning message will appear during the boot sequence indicating the bootloader is unlocked.
Wait for the phone to finish the factory reset and boot back into the Android setup screen. Troubleshooting Common Issues
If the app fails or gives an error, consider these common fixes:
Network Connection: Ensure you have a stable Wi-Fi connection, as the app needs to communicate with Asus servers.
Firmware Version: Some very old or very new firmware versions might block the tool. Ensure your system software is up to date.
Asus Account: Some regions require you to be logged into an Asus account on the device before the tool will function. Verification
To confirm the process worked, go to Settings > About Phone > Software Information and tap Build Number seven times to enable Developer Options. In Developer Options, look for the OEM Unlocking toggle; if it is greyed out and says "Bootloader is already unlocked," you have succeeded.
