How to Root Meizu MX4 Pro: Full Guide

Rooting your Meizu MX4 Pro gives you full administrative control over the Android system, allowing you to remove bloatware, install root-only apps, tweak performance, and customize the OS beyond its normal limits. This guide walks you through the entire process using a reliable, widely-used method. Before you start, understand that rooting voids your warranty and carries a small risk of bricking the device if steps are missed. You will need a Windows PC, a USB cable, and about 30 minutes.

What You’ll Need

  • Meizu MX4 Pro with at least 50% battery charge
  • Windows PC (Windows 7 or later)
  • Original USB data cable
  • Meizu USB drivers installed on the PC
  • KingRoot APK (version 4.5.1 or later) – download from a trusted source
  • SuperSU zip (latest stable version) – for replacing KingRoot
  • Custom recovery image (TWRP) for MX4 Pro – from XDA Developers or Meizu forums
  • ADB and Fastboot tools – download the platform-tools package
  • Backup of all important data (rooting can wipe data if bootloader is unlocked)

Step-by-Step

  1. Enable Developer Options and USB Debugging: On your phone, go to Settings > About Phone and tap Build Number seven times. Then go to Settings > Developer Options and enable USB Debugging and OEM Unlock (if available).
  2. Install Meizu USB Drivers on PC: Download and install the official Meizu USB drivers. Connect your phone to the PC with the USB cable and ensure it is recognized (check Device Manager). If drivers are missing, download from Meizu’s official support page.
  3. Unlock the Bootloader: This step wipes all data. With the phone off, hold Volume Up + Power to enter Fastboot mode. Connect to PC. Open a command prompt in the platform-tools folder and run: fastboot devices to verify connection. Then run fastboot oem unlock. Confirm on the phone screen if prompted. The phone will reboot and erase data.
  4. Install TWRP Recovery: After unlocking, boot back into Fastboot (Volume Up + Power). In the command prompt, run: fastboot flash recovery twrp.img (replace twrp.img with the actual filename of your TWRP image). Then run fastboot reboot.
  5. Boot into TWRP: Turn off the phone. Hold Volume Up + Power together until the TWRP logo appears. This may take a few seconds.
  6. Install KingRoot APK: Before booting into TWRP, copy the KingRoot APK to your phone’s internal storage. In TWRP, tap Install, navigate to the APK, and swipe to flash it. This installs KingRoot as a system app.
  7. Reboot and Run KingRoot: Reboot the phone normally. Open KingRoot app. It will automatically detect the device and offer to root. Tap Root and wait for the process to complete (usually 1-2 minutes). The phone may reboot automatically.
  8. Replace KingRoot with SuperSU (Recommended): KingRoot works but is often considered less reliable. Download the SuperSU zip and place it on internal storage. Boot back into TWRP, install the SuperSU zip, and then wipe cache/dalvik. Reboot. SuperSU will now manage root access.
  9. Verify Root: Install a root checker app from the Play Store (e.g., Root Checker Basic) or run adb shell su from PC. If it returns a # prompt, root is successful.

Common Mistakes

  • Skipping the bootloader unlock: Without unlocking, TWRP will not stick and root will fail. Always unlock first.
  • Using a wrong TWRP image: Ensure the recovery is specifically for the MX4 Pro (model M461). Flashing a recovery for another device can hard-brick.
  • Not backing up data before unlocking: The unlock wipes everything. Backup to PC or cloud first.
  • Ignoring driver issues: If Fastboot doesn’t see the device, install the drivers correctly or try a different USB port.
  • Flashing SuperSU before KingRoot: SuperSU requires an existing root to install properly. Always root with KingRoot first.

Tips

  • Use a USB 2.0 port on the PC for more stable connectivity.
  • Keep the phone charged above 70% to avoid shutdown during flashing.
  • After rooting, install a firewall app to control which apps get root access.
  • If you plan to install custom ROMs later, keep the TWRP recovery and SuperSU.
  • Make a nandroid backup in TWRP before any major system changes.
  • Disable automatic system updates to prevent the stock recovery from replacing TWRP.

Troubleshooting

  • Fastboot not recognizing the phone: Reinstall drivers, try a different cable, or run fastboot devices as administrator. Ensure the phone is in Fastboot mode (check screen).
  • TWRP boots but touch screen doesn’t work: This can happen with older TWRP builds. Try a newer TWRP version or use the physical volume keys and power button to navigate (if supported).
  • KingRoot fails to root: Ensure you have a stable internet connection for the first run. If it fails, try rebooting and running again. If still failing, reflash TWRP and try a different version of KingRoot.
  • Boot loop after rooting: Boot into TWRP (Volume Up + Power). Wipe cache and dalvik. If that doesn’t work, restore your nandroid backup or reflash the stock firmware via Fastboot.
  • SuperSU says “SU binary needs updating”: Open SuperSU and let it update via TWRP. It will reboot into recovery and install the binary automatically.
  • Phone stuck on Meizu logo: Hold power for 10 seconds to force restart. If it persists, boot into TWRP and wipe data/factory reset (this will erase data).

Frequently Asked Questions

Does rooting void the warranty?

Yes, rooting typically voids the manufacturer’s warranty. You can often restore the device to stock firmware to regain warranty, but it’s not guaranteed.

Will rooting delete my data?

Unlocking the bootloader wipes all data. The rooting process itself (after unlock) does not delete data, but it’s wise to backup before any step.

Can I unroot later?

Yes. You can unroot by restoring a stock firmware image via Fastboot or by using the “Unroot” option in SuperSU. This will also relock the bootloader if you choose to do so.

Is it safe to root the MX4 Pro?

Rooting is generally safe if you follow the steps correctly. The main risks are bricking if you flash the wrong files or interrupt the process. Always use device-specific files.

Will I still receive OTA updates after rooting?

Usually not. OTA updates may fail or cause issues because the system is modified. You can manually install updates or switch to custom ROMs.

What can I do with root that I can’t do without?

With root, you can remove preinstalled bloatware, use apps like Titanium Backup, install Xposed modules, overclock the CPU, and gain full control over system permissions.
