How to Unlock Bootloader on ASUS (ROG Phone) (2025)

 

Ultimate Guide to Unlocking the Bootloader on every ASUS ZenFone & ROG Phone (2020-2025)

⚠️ July 2025 status: ASUS officially disabled the classic “Unlock App” method on all new devices in 2024.
The only guaranteed ways today are:
  1. Downgrade to an old firmware (Android 13 or earlier) and use the mitmproxy trick
  2. Use the old official ASUS Unlock Tool if you still have it on a ZenFone/ROG released before July 2023
  3. Use the device-specific unlock batch file for the ZenFone Max Pro series
  4. Wait for an exploit or petition ASUS to re-open the service

Section A – New devices (ROG 6/7/8, ZF 9/10)

Only works on firmware older than Android 14 / WW-33.0820.0810.225 or below .

1. Preparation

2. Downgrade firmware (if you are on Android 14)

  • Grab the full raw Android 13 package from ASUS support site (e.g. WW-33.0610.2810.157 for ROG 6).
  • Flash via raw firmware script (fastboot or ADB sideload).
  • Do NOT take OTA after unlock!

3. mitmproxy bypass

  1. Install mitmproxy, open a terminal and run
    mitmproxy -s unlock.py
  2. Create unlock.py in the same folder with the exact content:
Python
Copy
from mitmproxy import http
def request(flow):
    if flow.request.host == "dm.asus.com":
        if "dm.asus.com/unlock/register" in flow.request.url:
            flow.request.urlencoded_form["apkVersion"] = "2.0"
            flow.request.urlencoded_form["swVer"] = "13..WW_AI2201-WW_user_9999999..999999.0610.2810.157..ASUS-ASUS_AI2201-WW"
Change AI2201 to your model (AI2205 for ROG 7, etc.) and the .157 to the exact build you flashed .
  1. Connect phone to same Wi-Fi as PC → Settings ▸ Wi-Fi ▸ Modify network ▸ Proxy → Manual → IP of PC, port 8080.
  2. Install the Unlock Tool APK on the phone → open it → agree → tap Unlock.
    • You’ll see no error → phone reboots → factory reset → bootloader unlocked.

4. After unlock – rooting (optional)

  • Extract boot.img from the same firmware zip.
  • Patch it with Magisk on the phone → magisk_patched-xxx.img.
  • adb reboot fastboot
    fastboot flash boot_a magisk_patched.img
    fastboot flash boot_b magisk_patched.img
  • Reboot → enjoy root + custom kernels/ROMs.

Section B – Older devices (ROG 5/3/2, ZenFone 5-8 series, etc.)

Official ASUS method (still alive)

  1. Enable Developer Options → USB debugging + OEM unlock.
  2. Install ASUS Unlock Tool from Play Store or APKMirror (v9.2.0.0_200807).
  3. Open tool → tap Press to Unlock → agree → phone reboots & wipes.
  4. Done – bootloader is unlocked.
  5. Flash TWRP, Magisk, custom ROMs at will.
If Play Store says “not compatible”, sideload the APK from APKMirror.

Section C – ZenFone Max Pro M1 / M2

ASUS never shipped the Unlock Tool here. Use the community batch file:
  1. Download Unlock package .
  2. Unzip → install drivers folder on Windows.
  3. Reboot phone to Fastboot (Vol Up + Power).
  4. Run unlock.cmd inside the unlock folder.
  5. Phone reboots with orange state – bootloader unlocked.
  6. Flash TWRP via fastboot flash recovery twrp.img.

1. Universal Safety & Legal Warnings

Table
Copy
RiskExplanation
WarrantyASUS policy: bootloader unlock immediately voids warranty in most regions. EU law may override this; check local consumer rights.
DRM / WidevineUnlocking drops Widevine L1 to L3 – Netflix, Disney+, etc. will stream at 480p max. Magisk + liboemcrypto.so patches exist but break every month.
SafetyNet / Play IntegrityRoot + unlocked bootloader triggers Play Integrity “MEETS_DEVICE_INTEGRITY” failure. Use Magisk 28+ with Zygisk + Play Integrity Fix module.
BrickingA single typo (fastboot erase persist) can permanently brick your phone. Always keep a raw firmware package on your PC.
Data LossEvery method forces a factory reset. Back up internal storage, WhatsApp, Signal, 2FA seeds, etc.

7. Method 4 – OEM Unlock Toggle + Fastboot (Edge Cases)

Some carrier variants (Verizon, Sprint JP) hide the OEM toggle.
  • Solution: flash retail firmware via raw fastboot → OEM toggle re-appears.
  • Then run:
bash
Copy
fastboot flashing unlock_critical
fastboot flashing unlock

<a name="edl">

8. Method 5 – EDL / Firehose “9008” for Hard-Bricked Units

Use only when phone is black screen, no fastboot, no recovery.
  • Download QFIL & corresponding prog_emmc_firehose_****.mbn file.
  • Short EDL test points → Qualcomm HS-USB 9008 appears → flash raw XML package.
  • After revive, follow Method 1 or 2 again.
