The Qualcomm Smartphone Write IMEI Tool v1.01 is a specialized utility used to restore or repair the International Mobile Equipment Identity (IMEI) number on devices powered by Qualcomm chipsets. This tool is typically utilized when a device’s IMEI has been corrupted (often showing as "0" or "Unknown") following a bad firmware flash, software crash, or motherboard repair. Key Features and Functionality
IMEI Restoration: Allows users to manually input and "write" the original IMEI back to the device's NVRAM/EFS partition.
Support for Multiple SIMs: Version 1.01 often features dual-input boxes, enabling the repair of both IMEI 1 and IMEI 2 for dual-SIM smartphones.
Diagnostic Mode Interaction: The tool communicates with the device through a "Diagnostic Port" (Diag Mode), which must be enabled on the phone via secret codes (like *#*#717717#*#* on some models) or ADB commands before the tool can detect it.
Lightweight Utility: Unlike comprehensive suites like Chimera Tool or Hydra Tool, this is a standalone, portable EXE file focused specifically on the IMEI writing process. General Usage Workflow
Driver Installation: Users must install the correct Qualcomm USB Diag drivers so the PC recognizes the device in diagnostic mode.
Enable Diag Mode: The smartphone must have "USB Debugging" enabled and be switched into Diagnostic Mode.
Writing Process: After the tool detects the COM port, the user enters the valid IMEI (found on the device box or under the battery) and clicks "Write" or "Start".
Verification: A successful operation is usually followed by a "Pass" message, after which the device must be rebooted to verify the change via *#06#. Important Considerations Disclaimer: This report is for informational purposes only
Legal & Ethical Use: In many jurisdictions, changing or altering an IMEI to a number other than the one originally assigned to the device is illegal. This tool should only be used for legitimate repair purposes (restoring the original IMEI).
Risk of Brick: Modifying EFS or NVRAM partitions carries risks. It is standard practice for technicians to back up the existing QCN (Qualcomm Calibration Network) file using tools like QPST before attempting to write a new IMEI.
Compatibility: While designed for Qualcomm chips, success rates vary by manufacturer (e.g., Xiaomi, Vivo, Oppo) due to different security levels and encrypted EFS partitions on newer Android versions. qualcomm smartphone write imei tool v1.01 latest 2017
