Frequently Asked Questions

What exactly is IMEI and why is it important?

IMEI stands for International Mobile Equipment Identity. It’s a unique 15-digit serial number that identifies your specific mobile phone on a global scale. It’s crucial for network identification, theft tracking, and ensuring your phone can connect to mobile networks. A null or invalid IMEI means your phone won’t be able to make calls, send texts, or access mobile data.

Is Qualcomm IMEI repair tool truly free? Are there any hidden costs or premium features?

Yes, the Qualcomm IMEI Repair Tool B19 v0.0.1 is genuinely 100% free to download and use. There are no hidden costs, subscriptions, paid activations, or premium features. It’s designed to be accessible to everyone who needs it for legitimate IMEI restoration.

It is legal to use this tool only for the purpose of restoring your phone’s original IMEI number. For example, if your phone’s IMEI became null after a software flash or mainboard replacement, you can legally use this tool to write back the original IMEI. However, deliberately changing or modifying your IMEI to a different, non-original number is illegal in many countries and can carry severe penalties.

My phone’s IMEI is showing “Null” or “Invalid.” Can this tool fix it?

Yes, the tool is specifically designed to address “Null IMEI” or “Invalid IMEI” issues on Qualcomm-based Android devices, provided you have access to the original IMEI number.

What if I don’t know my phone’s original IMEI number?

You must have your original IMEI number to use this tool. Without it, you cannot restore your IMEI. You can usually find your original IMEI on the phone’s original packaging box, on a sticker under the battery, on the purchase receipt or warranty card, or from a backed-up EFS/NVRAM partition.

Do I need root access to use Qualcomm IMEI Repair tool?

Generally, no. The tool operates through the Qualcomm DIAG port, which is a diagnostic mode and doesn’t always require full root access. However, you do need to enable USB Debugging and successfully activate DIAG mode as per the instructions.

The tool isn’t detecting my phone’s COM port. What should I do?

This usually indicates a driver or DIAG mode issue. Ensure Qualcomm USB Drivers are correctly installed, verify DIAG mode is enabled, try a different USB port or cable, and temporarily disable antivirus software.

This tool specifically addresses IMEI-related network issues. If your network problems are due to a faulty SIM card reader, antenna damage, or carrier issues, this tool will not resolve them.

Is it safe to use this tool? Can it brick my phone?

When used correctly and according to the instructions, the tool is generally safe. However, improper use, entering incorrect IMEI numbers, or interrupting the process can potentially cause further software issues. Always proceed with caution.

Where can I find the latest version of this tool or similar tools?

You can always find the latest updates and related tools on GSM6.com. We regularly update our resources to provide the best solutions for mobile device repair and unlocking.

What Qualcomm chipsets does this tool support?

The tool supports most Qualcomm Snapdragon chipsets including 4xx, 6xx, 7xx, and 8xx series. It works with devices using Qualcomm modems that have accessible DIAG ports.

How do I enable DIAG mode if dialer code doesn’t work?

If *#*#717717#*#* doesn’t work, try alternative codes: *#*#13491#*#*, *#*#3646633#*#*, or use ADB command: adb shell setprop sys.usb.config diag,adb. Some devices may require root for DIAG mode activation.

Can I use this tool for multiple phones?

Yes, you can use the same tool installation for multiple Qualcomm devices. Just ensure you’re entering the correct original IMEI for each specific device.

What should I do if tool shows “Write Failed” error?

Check: DIAG mode is active, correct COM port selected, Qualcomm drivers installed, different USB cable/port, phone battery >50%, run tool as administrator.

Does this tool backup original IMEI before writing?

No, this tool doesn’t include backup feature. Always manually note down or backup your original IMEI before any repair operations using other tools like QPST.

Can this tool fix IMEI on locked bootloader devices?

Usually yes, if DIAG mode can be activated. Some carriers may lock DIAG access on bootloader-locked devices, requiring bootloader unlock first.

What Windows versions are supported?

Windows 7, 8, 8.1, 10, and 11 (both 32-bit and 64-bit). May require compatibility mode settings on newer Windows versions.

Is internet connection required for this tool?

No, the tool works completely offline once downloaded. No internet connection is needed for IMEI writing operations.

How do I find my phone’s COM port number?

Connect phone in DIAG mode, open Windows Device Manager > Ports (COM & LPT). Look for “Qualcomm HS-USB” or similar entry with COM number.

Can I repair dual IMEI with this tool?

Yes, the tool supports both single and dual SIM devices. Enter IMEI1 for SIM1 slot and IMEI2 for SIM2 slot if applicable.

What’s the difference between this and paid IMEI repair boxes?

This tool provides basic IMEI writing via DIAG port for free. Paid boxes often offer more features like direct NV item editing, cert writing, and support for more security levels, but for basic IMEI restoration, this free tool is sufficient.
