The MTK Feature Phone IMEI Repair Tool (often referring to specialized utilities like WriteCode IMEI Tool or Maui Meta) is a lightweight, portable Windows application designed to restore or update the International Mobile Equipment Identity (IMEI) number on MediaTek-powered devices. These tools are essential for fixing "Invalid IMEI" or "Null IMEI" errors that occur when the device's NVRAM or partition data is corrupted during software flashing. Key Features
Portability: Most versions are fully portable, requiring no installation; you simply run the executable file after extraction.
Database Integration: Newer tools often include internal "AP DB" files, meaning you don't need to manually hunt for database files to complete the flashing process.
Support for Multiple SIMs: Tools like SN Write Tool specifically handle devices with dual-SIM slots, allowing simultaneous repair of both identifiers.
Compatibility: They typically support a wide range of MTK-based hardware, from older keypad feature phones to modern smartphones. User Experience & Use Case
Technicians and DIY users generally find these tools effective because they operate in "Meta Mode" or "AT Mode," allowing direct hardware interaction via a USB connection.
Pros: Highly effective for restoring network connectivity on "bricked" or software-damaged phones.
Cons: Requires specific MTK USB drivers to be installed on the PC first, and incorrect use can potentially damage the device's firmware further.
For MediaTek (MTK) feature phones, IMEI repair tools are specialized software used to restore a lost or "invalid" IMEI number, typically caused by firmware corruption or a failed flashing process. These tools are critical because a phone without a valid IMEI cannot register on a mobile network to make calls or send texts. Commonly Used Tools
Several tools are frequently cited by experts and technicians for MTK-based devices:
SN Write Tool: A standard utility used specifically for writing serial numbers and IMEIs on MediaTek devices, supporting both single and dual-SIM configurations.

Writing the ID: Entering the 15-digit IMEI found on the physical sticker under the phone's battery into the tool and clicking "Write" while the phone is connected via USB. Legal and Ethical Warning It is important to distinguish between repair and changing.

Miracle Box (or Thunder Edition): A popular "all-in-one" service tool used by repair shops that supports a wide range of MTK feature phones.
MTK Engineering Mode: A built-in "secret menu" accessible via dialer codes (e.g., *#*#3646633#*#*) on some models, allowing for manual entry without a PC. General Repair Process
Driver Installation: You must install the MTK USB VCOM Drivers so your computer can recognize the phone in service mode.
Preparation: Obtain the correct IMEI for the device and, if using SN Write Tool, the specific firmware database files for that model.
Connection: Power off the phone, open the tool, click "Start," and connect the phone to the PC via USB (sometimes while holding a "Boot Key" like the center button).
Writing: The tool identifies the device, enters META or Flash mode, and writes the 15-digit code to the hardware. Important Legal & Safety Warning
Legality: In many jurisdictions, changing an IMEI to a number other than the one originally assigned to the device is illegal. This process should only be used to restore the original, lost IMEI.
Risk: Incorrectly using these tools can "brick" the device (render it unbootable) or permanently damage the baseband, leading to no signal.
