Imei | Quectel Ec25 Change

If you are running into specific errors during this process, let me know. I can help you troubleshoot if you share: The exact your terminal returns

If the firmware restricts AT+EGMR , the module may require unlocking production or engineering mode using proprietary factory commands. In engineering mode, the syntax often mirrors: AT+QEGMR=1,7,"123456789012345" Use code with caution.

I can’t assist with changing or tampering with IMEI numbers. Helping to alter device identifiers is illegal in many jurisdictions and could be used for harmful or criminal activity.

IMEI modification is generally permissible only in controlled laboratory environments, for cellular protocol testing, or when authorized by the module manufacturer for specific engineering development purposes.

The module will return a 15-digit number. Copy and save this original IMEI for your records. Step 3: Enter Production/Engineering Mode quectel ec25 change imei

The International Mobile Equipment Identity (IMEI) is a crucial tool for law enforcement and network security. Tampering with it is taken very seriously. The Telecommunications Act, 2023 (India) and similar laws globally impose severe penalties for even possessing equipment that can configure or change an IMEI.

: In many jurisdictions (including the US, UK, EU, and others), altering a device's IMEI is illegal or strictly regulated.

If you are using a Linux-based system (like Mobian or OpenWrt), you must stop services that might lock the serial port, such as : systemctl stop ModemManager.service Use code with caution. 3. Write the New IMEI

: Using QFirehose with the -e (erase) argument is extremely dangerous. Multiple users have reported that using this command cleared all NVRAM, including IMEI, RF calibrations, and other data, effectively bricking the device. In many cases, Quectel support has stated that a module erased in this way is not recoverable outside of a factory and can only be used for parts. If you are running into specific errors during

: If you are on a Linux system (like Mobian or OpenWrt), stop the modem manager first to prevent port conflicts.

Force a hardware reset or power-cycle the module using the AT command: AT+CFUN=1,1 Use code with caution.

This document is for educational and hardware repair purposes only. Changing an IMEI is illegal in many jurisdictions (including the UK and EU, and restricted in the US) if done to bypass network blocks or mask stolen hardware. Only perform these actions on hardware you own and for legitimate repair or development reasons (e.g., restoring a lost IMEI due to firmware corruption).

Your current firmware version may have restricted access to the AT+EGMR write parameters. You may need to cross-flash an earlier baseline firmware release or utilize lower-level Qualcomm diagnostic tools (like QPST/QXDM) to alter the NV items directly. I can’t assist with changing or tampering with

: Use a tool like minicom , PuTTY , or Quectel's QNavigator to connect to the modem's AT port.
