Mobileuncle Mtk Imei Write Tool Hot! May 2026

The Mobileuncle MTK Tools app is a utility for Android devices with MediaTek (MTK) chipsets that allows users to access "Engineer Mode" to restore or modify device information, including the IMEI number. How to Write/Restore IMEI Using Mobileuncle Tools

This process is typically used to fix "Invalid IMEI" errors after flashing a new ROM. Note that your device must be rooted and have the MediaTek chipset to use this specific method.

Preparation: Dial *#06# to check your current IMEI. If it is null or invalid, locate your original IMEI number on the device's box or under the battery.

Access Engineer Mode: Open the Mobileuncle MTK Tools app and select Engineer Mode > Engineer Mode (MTK).

Navigate to Connectivity: Swipe to the "Connectivity" tab and select CDS Information > Radio Information.

Select Phone Slot: Choose Phone 1 for the first SIM slot. You will see a command line starting with AT+. Enter the Command: For SIM 1: Type AT+EGMR=1,7,"YOUR_IMEI_NUMBER" For SIM 2: Type AT+EGMR=1,10,"YOUR_IMEI_NUMBER"

Note: Ensure there is a space after "AT+" (e.g., AT +EGMR...) if the command fails initially.

Finalize: Tap SEND AT COMMAND. You should see a "command sent" message. Restart your device to apply the changes. Important Considerations

Legal Restrictions: Changing an IMEI to anything other than the original factory-assigned number is illegal in many jurisdictions. This tool should only be used to restore a lost original IMEI.

Modern Alternatives: For newer MediaTek devices where Mobileuncle may be outdated, factory tools like the SN Writer Tool or paid services like the Unlock Tool are often used for more reliable results on current Android versions.

The Mobileuncle MTK Tool is a utility application designed for Android devices powered by MediaTek (MTK) chipsets. While it offers a range of advanced "Service Mode" features—such as updating recovery or modifying system parameters—its "IMEI Write" functionality is one of its most critical, yet controversial, capabilities. Overview and Functionality

The tool acts as a bridge for users to access the MTK Engineering Mode, a hidden settings menu usually reserved for factory testing and hardware diagnostics.

IMEI Restoration: Its primary legitimate use is repairing a "null" or "invalid" IMEI (International Mobile Equipment Identity). This often occurs when a device's NVRAM (Non-Volatile Random-Access Memory) is corrupted during firmware flashing or custom ROM installation, leaving the phone unable to connect to cellular networks.

Device Management: Beyond IMEI tasks, users utilize the app to back up and restore IMEI/NVRAM data, update recovery images without a PC, and adjust connectivity settings. Operating Process mobileuncle mtk imei write tool

Using the tool typically requires root access to modify the device's identity at the system level. The basic process involves: Opening the MTK Engineer Mode via the app.

Navigating to Connectivity > CDS Information > Radio Information.

Entering specific AT commands (e.g., AT +EGMR=1,7,"IMEI_NUMBER") to write the device's original 15-digit identifier. Risks and Legal Considerations

While restoring an original IMEI is generally considered a repair, modifying or cloning an IMEI to a different number is illegal in many countries, including the U.S., UK, and India.

The Mobileuncle MTK Tool is a utility designed for Android devices powered by MediaTek (MTK) chipsets. It provides access to advanced system settings, commonly known as Engineering Mode, which allows users to perform tasks like restoring a missing or corrupted IMEI (International Mobile Equipment Identity). Tool Overview

Purpose: Primarily used for system configuration, hardware testing, and IMEI restoration on MediaTek-based smartphones (e.g., Infinix, Tecno, Oppo, and older Xiaomi models).

Key Feature: Grants access to the MTK Engineering Mode menu without requiring complex terminal commands.

Requirement: Some advanced functions, like writing a new IMEI, may require the device to be rooted or have specific frameworks like Xposed installed. IMEI Writing Procedure (via Engineering Mode)

If you are using Mobileuncle to restore an IMEI, the process typically involves navigating through the MTK internal menus:

Enter Engineering Mode: Open the app and select "Engineer Mode (MTK)" or dial *#*#3646633#*#* on your keypad.

Access Connectivity Settings: Navigate to the Connectivity tab and select CDS Information.

Radio Information: Select Radio Information, then choose the specific SIM slot (e.g., Phone 1 or Phone 2). Enter AT Command: For SIM 1: Type AT+EGMR=1,7,"YOUR_NEW_IMEI" For SIM 2: Type AT+EGMR=1,10,"YOUR_NEW_IMEI"

Save and Restart: Click Send AT Command and reboot your device to apply the changes. Popular Alternative Tools

If Mobileuncle is incompatible with your specific MTK version, several professional PC-based alternatives are widely used:

SN Write Tool: A robust factory-level utility for flashing IMEI, Serial Numbers, and Bluetooth addresses. A safe, legal deep technical explanation of how

Maui META: Used for more complex repairs where the NVRAM or database files are required to sync with the hardware.

ChimeraTool: A paid service software that supports IMEI patching for a wider variety of modern MTK devices. Critical Warnings

Step 5: Select Radio Information

You will see two options:

Tap on Phone 1.

Part 9: The Future of IMEI Repair on MTK Devices

As of 2025, MediaTek has tightened security. Newer Dimensity chips (7200, 9000, 9300) use hardware-level attestation. Tools like MobileUncle simply do not work on these modern SoCs because the NVRAM is encrypted and signature-checked at boot.

The industry is moving toward:

For older phones (pre-2020), MobileUncle remains a nostalgic, effective lifesaver. For modern devices, you need authorized service center access.

Step 3: Locate IMEI Write Option

The Double-Edged Scalpel

This simplicity is what makes MobileUncle so fascinating and so controversial. It is a scalpel: in the right hands, it saves lives; in the wrong hands, it commits forgery.

The Legitimate Use (The Hero): Across developing economies, billions of people rely on $50–$100 MTK-powered smartphones. These users cannot afford authorized service centers that may charge more than the phone is worth. When a firmware update corrupts the IMEI partition—a common flaw in cheap phones—MobileUncle is the only affordable fix. Street-side phone "doctors" restore connectivity in under two minutes, charging less than a dollar. Without this tool, millions of working phones would become e-waste.

The Illegitimate Use (The Villain): The same tool allows thieves to change a stolen phone’s IMEI, effectively giving it a new identity. Blacklisted IMEIs—reported stolen or lost—can be overwritten. The phone rejoins the network, untraceable. Law enforcement and carriers despise MobileUncle for this reason. In India and Bangladesh, authorities have tried to ban its distribution and criminalize its use. Yet the APK file spreads via Bluetooth, Telegram groups, and file-sharing sites like a digital weed.

Part 5: Advanced Features – Backup and Restore

Writing IMEI manually via AT commands is tedious. The newer versions of MobileUncle include a simpler "IMEI Backup & Restore" feature:

  1. Tap "IMEI Backup & Restore" from the main menu.
  2. Choose "Backup IMEI to SD Card" . This creates a file (e.g., IMEI.bak).
  3. To restore later, simply choose "Restore IMEI from SD Card" .

This is the safest way to recover from future ROM flashes.

The Risks and Downsides

While MobileUncle is powerful, it is not without serious caveats:

  1. Permanent NVRAM Corruption: If you write the wrong data format or interrupt the process, you may corrupt the NVRAM entirely, requiring a full format and re-flash via SP Flash Tool.
  2. Security Implications: Writing an IMEI that does not match the original sticker is illegal in most countries (including the US, UK, India, and EU nations). It is considered tampering with a device identifier.
  3. Blacklist Issues: Using a cloned or invalid IMEI can lead to the phone being permanently blacklisted by all carriers if detected.
  4. Modern MTK Chips: On newer MediaTek processors (Helio G-series, Dimensity), MobileUncle may no longer work due to enhanced security (AVB 2.0, secure NVRAM). Modern devices require PC-based tools like Maui META or SN Write Tool.
