Qualcomm chipsets have moved to Secure Boot v2 and v3. Tools like QLM often try to write to protected partitions (like modemst1, modemst2, or fsg).
Even with the "better free tool," you may encounter errors. Here is how to fix them.
Error 1: "Device not in Diag mode"
Error 2: "Write Failed - Security Denied"
Error 3: Tool crashes on launch
While many free tools only work on legacy chipsets (MSM8225, MSM8960), QLM v102 has been updated to handle modern SoCs. Reports indicate successful repairs on:
The QLM IMEI Repair Tool v1.02 stands out as an efficient, user-friendly, and cost-effective solution for servicing Qualcomm Android devices. By offering essential features like IMEI rewriting, QCN backup/restore, and broad CPU support without the price tag of professional dongles, it levels the playing field for smaller repair shops and independent enthusiasts.
However, with great power comes great responsibility. Users must proceed with caution and ensure they are adhering to legal standards when performing repairs.
Note: Always ensure you scan any downloaded software for malware and create a full backup of your device data before proceeding with any system-level repairs.
For Qualcomm devices, several free tools and methods are available for IMEI repair and writing in 2026.

The QLM IMEI Repair Tool v1.0.2 is a lightweight utility designed to restore or repair IMEI numbers on Qualcomm-based devices. It typically works by modifying and flashing QCN (Qualcomm Calibration Network) files to fix issues like "Invalid IMEI" or "00 IMEI". Key Features of QLM IMEI Tool

Dual IMEI Support: Capable of repairing both IMEI 1 and IMEI 2 on supported devices.

If you need a more robust or modern tool, these are widely used in the community:
QPST/QFIL: The official Qualcomm utility for backup and restore of QCN files.

Changing an IMEI number is illegal in many countries and can lead to permanent blacklisting or legal action. Only use these tools to restore the device’s original IMEI after a software corruption or repair.
Security Risk: Many free tool links (like those on Google Drive) can contain malware. Always scan downloads with a tool like ANY.RUN or Virustotal before running them.
Backup First: Always take a full backup of your EFS and QCN partitions before making changes. To help you find the right setup, could you tell me: The model of your device?

If your phone says "Invalid IMEI" after a firmware update, do not download a random executable.
Here is the professional workflow that actually works:
Many "free" tools are demo versions that limit repairs to a single use or display a paywall after detecting the device. QLM v102 has no credit system, no time bombs, and no "premium upgrade" nag screens for basic IMEI repair on supported models.
Beyond just IMEI, the tool allows users to backup and restore QCN files. This is crucial for saving a phone's baseband configuration before attempting risky repairs. If a phone loses its signal or displays "Unknown Baseband," restoring a previously saved QCN (or a generic one) often resolves the issue.
