The Asus Zenfone Max 3 is a mid-range Android phone released in late 2016. Its features are a 13mp rear camera, 3GB of RAM, and the slick ZenUI interface. This device shipped with two different chipsets – the MT6737T and the MT6737M. This guide is only for the MT6737T chipset version of this device. You can use an app like CPU-Z to see which one you have.
Optional to download, but recommended to always have a stock ROM in case of device failure.
How to Root the Asus Zenfone 3 Max (MT6737T Chipset)
- Begin by downloading and extracting the Mediatek USB drivers to somewhere on your computer. These drivers allow the SP Flash Tool to properly communicate with basically all Mediatek chipset devices.
- We need to disable Driver Signature Enforcement in Windows, so Press Windows Key + X and choose “Command Prompt (Admin)” from the menu. Now type into the command terminal:
bcdedit /set testsigning on
The terminal will output “The operation was completed successfully”, so restart your PC. When it boots back to your desktop, you will see a “Test Mode” watermark in the bottom-right corner of your screen.
Note: If your command prompt returned “The value is protected by Secure Boot policy”, then Secure Boot must be disabled in your BIOS settings. Refer to your BIOS manual.
- Open Device Manager on your computer – the easiest way is to hold Windows Key + R to open the Run command, and type “devmgmt.msc” and click OK.
- Click on your computer’s name, and then click the Action tab, and choose “Add Legacy Hardware”. Click Next in the Hardware Wizard box, then choose “Install the Hardware that I manually select from a list”, and click Next again.
- Enable “Show All Devices” before clicking Next, then “Have Disk” > Browse > navigate to your Mediatek drivers folder you extracted earlier. Be very careful which driver you choose to install, you must choose only the driver for your Windows version and system type (e.g. Windows 10 64-bit or Windows 7 32-bit).
- Now choose the Mediatek Preloader USB VCOM Port and click Next a couple times, then wait for the driver installation to finish. If an error comes up like “This Device Cannot Start (Code 10)”, just click Ignore and Finish.
- Now extract the TWRP recovery to your desktop, and also extract the SP Flash Tool. Run the Flash_Tool.exe with Administrator privileges.
- In the SP Flash Tool, click the “Browse” tab and then navigate to your TWRP folder. Select the “scatter.txt” file for your device. Now uncheck all of the options except Recovery.
- Enable USB Debugging on your Infinix Note 3 Pro under Settings > Developer Options. If Developer Options is not enabled, go to Settings > About > tap “Build Number” 7 times until it notifies you that Developer Options is now granted.
- Turn off your phone, and click the Download button in the SP Flash Tool. Connect your phone to your computer via USB, and the SP Flash Tool will automatically begin installing TWRP. You’ll see a green button in SP Flash Tool when it’s done.
- Now transfer the SuperSu.zip file to your phone’s SD card, turn off the device, and boot into TWRP recovery mode (hold Power + Volume Up).
- In the main menu of TWRP, choose “Install”, then navigate to your SD card and select the SuperSu.zip file you transferred over. Swipe right to install, and then reboot your device when it’s done.
