Official Support Status: In 2024 and 2025, many users have reported that ASUS's official unlock servers are often down for "maintenance," which may cause the APK to fail with connection errors.

OTA Updates: Once unlocked, you will no longer receive official over-the-air (OTA) system updates from ASUS.

If you find the APK method no longer works due to server issues, you may eventually need to use a PC-based unofficial "unlock.bat" script to bypass the official server check.

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. how to unlock bootloader asus zenfone max pro m1 without pc

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.

Since the tool is an APK from outside the Google Play Store, you must allow your browser or file manager to install it. Go to Settings > Security & lock screen.

Enable Unknown sources (for older Android versions) or grant permission to your File Manager app to "Install unknown apps." 2. Download and Install the Official Asus Unlock Tool

Download the Unlock Tool APK for the Zenfone Max Pro M1. You can find it on official Asus Support Pages (search for your specific model) or via community mirrors like XDA Developers.

Important Disclaimer:

  • Warranty Void: Unlocking the bootloader will void your device warranty.
  • Data Loss: This process will wipe all data on your phone. Please back up your photos, contacts, and files before proceeding.
  • Risk: There is always a small risk of bricking your device. Proceed at your own risk.

4. Risks and Warnings

Before attempting any unlock procedure, the user must be aware of the following:

  • Data Wipe: Unlocking the bootloader performs a full factory reset. All data, photos, and apps will be deleted.
  • Warranty Void: This process voids the manufacturer warranty.
  • SafetyNet/Play Store Issues: Unlocking the bootloader often fails Google's SafetyNet check, resulting in apps like Netflix or banking apps refusing to run (though this can often be bypassed later with Magisk).
  • Brick Risk: Interrupting the process or using incorrect files can "hard brick" the device, rendering it unusable.

Prerequisites: What You Need Before Starting

Since you are not using a PC, you must prepare your phone manually. Follow these steps exactly:

  1. Charge your battery: Ensure your ZenFone Max Pro M1 has at least 70% battery. A failure during unlock can brick the device.
  2. Backup everything: Use Google Drive, a USB OTG drive, or an SD card to back up your data. The unlock process triggers a factory reset.
  3. Enable Developer Options: Go to Settings > System > About Phone and tap "Build Number" 7 times.
  4. Enable OEM Unlocking: In Developer Options, toggle "OEM Unlocking" ON. If this option is greyed out, you cannot proceed without an internet connection (Asus servers need to verify your device).
  5. Enable USB Debugging: In the same menu, enable "USB Debugging" (this is usually needed for apps to send commands locally).
  6. Install a Terminal Emulator: Since we have no PC, we need a way to run shell commands. Download Termux (from F-Droid or a trusted APK mirror) or Material Terminal from the Play Store.
  7. Know your device state: This method works best on the Firmware version ending in .339 or older. Newer firmwares (Android 9/10 stock) have patched the fastboot vulnerabilities that allow PC-less unlocking.

What If It Fails? (Troubleshooting)

Since you have no PC, your troubleshooting options are limited. Here are the common failures:

Step-by-Step Process:

Step 1: Prepare the "Host" Phone Install a terminal emulator app (like Termux) on the second Android phone. Ensure it is rooted and has fastboot binaries installed (download "Android Platform Tools" for ARM from GitHub).

Step 2: Enable Developer Options on ZenFone

  • Go to Settings > System > About Phone.
  • Tap Build Number 7 times.
  • Go back to Settings > System > Developer Options.
  • Enable OEM Unlocking and USB Debugging.

Step 3: Connect via OTG

  • Plug the OTG cable into the host phone.
  • Connect the standard USB cable to the OTG.
  • Connect the Micro-USB end to the ZenFone. The host phone should recognize the ZenFone as a USB device.

Step 4: Reboot to Bootloader On the ZenFone, run the command (using a terminal app or ADB over WiFi if available, but physical connection is better): adb reboot bootloader Once the ZenFone shows the "START" screen (fastboot mode), you are in the bootloader.

Step 5: Send the Unlock Command On the host phone’s terminal, type: fastboot oem unlock The ZenFone will show a warning screen. Use the volume keys to select "Yes" and press power.

Result: Bootloader unlocked. This method works because many Asus ZenFone Max Pro M1 units shipped with a vulnerability that allowed fastboot oem unlock without an official token.

3. The "One-Time PC" Alternative (The Minimalist Approach)

If the goal is to avoid relying on a PC for the long term (e.g., installing custom ROMs later), there is a method that requires a PC only once to unlock the device. This is the closest achievable solution to the user's request.

Prerequisites:

  • A PC (used only for the unlock process).
  • Standard USB Cable.
  • Internet connection on the PC.

The Procedure:

  1. Enable Developer Options: Go to Settings > About Phone > Tap "Build Number" 7 times.
  2. Enable OEM Unlocking: Go to Settings > Developer Options > Enable "OEM Unlocking".
  3. Download Tools: On the PC, download the ASUS Unlock Device App (extracted from ASUS support) and Minimal ADB and Fastboot.
  4. Boot to Fastboot: Connect the phone to PC. Open ADB terminal. Type adb reboot bootloader.
  5. Unlock Command: Type fastboot oem unlock (or use the specific unlock binary provided by ASUS).
  6. Confirmation: Use volume keys on the phone to confirm the unlock.

Note: Once the bootloader is unlocked using this one-time PC connection, the user can then boot into a custom recovery (TWRP) and flash ROMs directly using an SD card or internal storage, removing the need for a PC for future modifications.

Error: "OEM Unlocking is greyed out"

  • Cause: Your phone is carrier-locked, or you don't have an active internet connection for Google servers to verify.
  • Fix (no PC): Insert a SIM with data, connect to Wi-Fi, and wait 24 hours. If it remains grey, you need a PC to manually flash the engineering bootloader.
