AR SuperCraft: Free Super.img Creator Tool for Oppo and Realme MediaTek Devices
Anyone who has repaired Oppo or Realme phones with MediaTek chipsets knows the frustration of opening a firmware package and finding loose raw partition images instead of a single flashable super.img file. AR SuperCraft, a free utility published by AR Education, was built to solve exactly this problem. The tool reads the super_def.json metadata file inside the firmware's META folder and combines the raw partition images into one super.img.
The tool is aimed at mobile repair technicians and flashing enthusiasts who regularly work with Oppo and Realme MediaTek firmware. In this article, we explain what AR SuperCraft does, list its features and requirements, walk through the usage steps shared by the developer, and cover the precautions you should take before flashing anything to a phone. All tool-specific details here are based on information published by AR Education, the developer of the tool.

What's New in AR SuperCraft
The developer has not published a version number or changelog for this release, so version details are not specified. What is confirmed is that AR Education has released the tool for the mobile repair community and states that it has been tested extensively on Oppo and Realme MediaTek firmware with promising results. If the developer publishes version updates later, this section can be revised accordingly.
Key Features
- Builds super.img from raw partitions. The core function of AR SuperCraft is to combine raw partition images found inside a firmware package into a single super.img file.
- Works with super_def.json metadata. The tool depends on the super_def.json file located in the firmware's META folder, which describes the partition layout of the device.
- Free to use. The developer distributes the tool at no cost to support the mobile repair community.
- Simple two-step workflow. Based on the documented process, usage is limited to selecting the super_def.json file and clicking "Make Super".
- Built-in disclaimer. The tool displays a disclaimer on launch and requires you to accept it before proceeding, which encourages careful use.
- Runs on Windows. The developer has tested the tool on Windows 10 and Windows 11.
- Error reporting channel. If the tool throws an error, the developer asks users to send a report via WhatsApp so the issue can be resolved.

How AR SuperCraft Works
Since Android 10, most new devices use dynamic partitions. Instead of separate system, vendor, and product partitions with fixed sizes, these images sit inside a single storage area known as the super partition. Many Oppo and Realme MediaTek firmware packages ship the individual raw images along with a metadata file named super_def.json, which defines how those images fit together, including partition names and grouping.
AR SuperCraft reads this super_def.json file and uses that information to pack the raw partition images into a properly structured super.img. This removes the need to arrange partitions manually or rely on lengthy command-line packing procedures. The developer has not documented the internal implementation publicly, but the input (super_def.json plus the firmware's raw images) and the output (a single super.img) are clearly defined.
How to Use AR SuperCraft
Before you begin, make sure your firmware package contains the META folder with super_def.json inside it, and that you are using a Windows 10 or Windows 11 PC.
- Get the AR SuperCraft archive from AR Education's official distribution channel. The ZIP file is password protected; the password is 1111.
- Extract the ZIP file to a folder on your PC.
- Run AR_SuperCraft.exe.
- Read the disclaimer and click "Agree" to continue.
- Select the super_def.json file from your firmware's META folder.
- Click "Make Super" and wait for the tool to build the super.img file.
- If you face any error, the developer requests that you send an error report via WhatsApp so it can be resolved.
The developer has not specified the exact output location or any post-build options, so follow any on-screen prompts shown by the tool.
Frequently Asked Questions
1. What is AR SuperCraft used for?
AR SuperCraft is a free Windows tool that creates an Android super.img file by combining raw partition images from a firmware package, mainly for Oppo and Realme MediaTek devices.
2. Is AR SuperCraft free?
Yes. The developer, AR Education, distributes the tool free of cost for the mobile repair community.
3. Where do I find the super_def.json file?
It is located inside the META folder of your firmware package. This file is mandatory; the tool cannot work without it.
4. What is the password for the AR SuperCraft ZIP file?
According to the developer's distribution details, the archive password is 1111.
5. Which PCs and phones are supported?
The tool runs on Windows and has been tested on Windows 10 and 11. Its output is intended for Oppo and Realme MediaTek devices. Compatibility with other devices has not been specified.
6. Can AR SuperCraft create a super.img without super_def.json?
No. The developer lists super_def.json as a mandatory requirement for the tool to function.
7. Does AR SuperCraft flash the super.img to my phone?
The developer's documented function for the tool is super.img creation only. No flashing function is specified, so you would use your usual flashing workflow afterwards, with appropriate caution.
8. Is AR SuperCraft safe to use?
The tool runs on your PC, so it does not directly modify a connected phone. The risk arises at the flashing stage, where the developer warns that improper use can brick the device or cause data loss. Always back up first and use firmware that matches your device model.
Conclusion
AR SuperCraft fills a narrow but genuine gap in the Oppo and Realme MediaTek repair workflow. It is free, easy to operate, and depends on just one input file, which keeps the process predictable. Its main boundaries are equally clear: it needs super_def.json, it targets a specific device segment, and flashing carries real risk. If you work with this category of firmware regularly, the tool is worth keeping in your toolkit, provided you back up every device before you flash.
