On vulnerable X00TD builds, a privilege escalation exploit can grant temporary root. Use the known "ASUS Unlock Token" vulnerability:
Without actual root, you cannot proceed. However, a known workaround for X00TD on Android 8.1 involves using the fastboot binary compiled for ARM running inside Termux. You can download fastboot for Android from GitHub (e.g., fastboot-arm64).
If you somehow have root access already (via an exploit like KingoRoot—though risky), you can unlock directly.
If "without PC" means "without a Windows laptop," you have options: how to unlock bootloader asus zenfone max pro m1 without pc
| 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.
Between 2018 and 2019, a developer known as Sujeet created an APK specifically for the ZenFone Max Pro M1 that exploited a vulnerability in Asus's early firmware. This app sends a raw command to the bootloader without needing a PC. On vulnerable X00TD builds, a privilege escalation exploit
This is the only reliable "no PC" method.
This report evaluates the possibility of unlocking the bootloader on the ASUS ZenFone Max Pro M1 without the use of a personal computer. Based on technical analysis of the device's partition structure and ASUS's security protocols, it is concluded that a "True No-PC Unlock" is impossible. However, a "One-Time PC Setup" method exists that allows the user to unlock the bootloader without a PC after the initial setup.
Users seeking a 100% PC-free solution will be unable to proceed due to hardware driver requirements and partition flashing restrictions. Without actual root, you cannot proceed
Connect a USB keyboard to your ZenFone via OTG. Reboot to fastboot (using hardware keys: Power + Volume Up). In fastboot mode, the keyboard can type commands? No. Fastboot mode does not accept keyboard input—only USB host commands. So this fails.
Developers have created APKs that contain the fastboot binary packaged for Android. This allows you to run fastboot commands targeting your own device using a local loopback.
However, due to Android security restrictions (root access is required to send fastboot commands to the bootloader), this method requires root access first. But you need an unlocked bootloader to root. It’s a chicken-and-egg problem.
The Workaround: You must have already unlocked via PC once, or you are on a very old firmware that has a known exploit. For 99% of users, Method 1 is obsolete. Do not waste time looking for a "Fastboot APK" – it won’t work without root.
Verdict: Impractical. Move to Method 2.
