The ZTE MC801A is a powerful 5G router powered by the Qualcomm Snapdragon X55
chipset. Changing its IMEI is a technical process typically used to repair a corrupted identity or to use specific data plans that are restricted to certain device types. ⚠️ Legal & Safety Disclaimer:
Changing an IMEI is illegal in many jurisdictions (such as the UK and parts of the US) and can result in the device being blacklisted by carriers. Proceed with extreme caution and only for legitimate repair purposes. 🛠 Prerequisites for the Process
Before attempting to modify the device's internal parameters, you must have the following: Qualcomm Diag Drivers:
Essential for the PC to recognize the modem's diagnostic port. ADB Access: To trigger the diagnostic mode on the router. NV Editing Tools: Software like QPST (Qualcomm Product Support Tool) or specialized ZTE Qualcomm Writers A Windows PC:
Most diagnostic tools for Qualcomm chipsets are Windows-exclusive. 🚀 The Technical Workflow
The general deep-level process for modifying the IMEI on an MC801A involves moving the device from its standard "Router Mode" into a "Diagnostic Mode." 1. Enable Diagnostic Port (Diag Mode)
By default, the MC801A only exposes its web interface and network ports. To change the IMEI, you must open the Qualcomm HS-USB Diagnostics
Connect the router via USB-C (some versions require a specific USB-A to USB-A cable or internal header access). ADB (Android Debug Bridge) to send the command: adb shell setprop sys.usb.config diag,adb
Once successful, you will see a new "Qualcomm HS-USB Diagnostics" entry in your Windows Device Manager. 2. Backup NV Items (Crucial Step) Never modify a router without a backup. The NV (Non-Volatile) items contain your device's unique calibration data. QPST Software Download tab and save an file of your current configuration. 3. Modifying the IMEI There are two primary ways to write the new IMEI: Using ZTE Qualcomm Writer: Select the Diag port in the software. Input the new 15-digit IMEI. Click "Write IMEI" or "Repair". Using QXDM Professional: Connect via the Diag port. Navigate to NV Browser (NV_UE_IMEI_I). The IMEI is stored in hexadecimal
format using a specific byte-swapping method (e.g., if the IMEI starts with 35, the hex often starts with 0x08 0x3A...). Write the new value and commit changes. ⚠️ Potential Risks & Troubleshooting Brick Risk:
Writing incorrect NV items can permanently disable the 5G/4G modem. Checksum Errors:
Some versions of the MC801A firmware have protected NV items. If the checksum doesn't match, the router will ignore the new IMEI upon reboot. Firmware Version:
Newer firmware (B14 and above) often locks the Diag port or requires a "Factory Password" to unlock the shell. 🔍 Verification zte mc801a change imei
After the process, the router must be rebooted to apply changes. You can verify the success by: Checking the Status Information page in the Web UI (192.168.0.1). Sending the AT command via a terminal emulator like Putty or TeraTerm.

Changing the IMEI (International Mobile Equipment Identity) of a device like the ZTE MC801A is a highly technical and often restricted process. Legal and Practical Warnings
In many countries, changing or "repairing" an IMEI is illegal. It can lead to the device being blacklisted by mobile networks or result in criminal charges. Warranty & Risk:
Attempting to modify core system identifiers typically voids your warranty and carries a high risk of "bricking" (permanently disabling) the router. Network Security: IMEI numbers are used by carriers like
to identify valid devices on their network; mismatching them can cause connection failures. Standard Methods for Accessing ZTE Settings
If you are trying to manage your router or resolve connectivity issues, you can access the standard administrative interface using these steps: Connect to the Router:
Plug your PC into the router with an Ethernet cable or connect via Wi-Fi. Find Credentials:
Check the sticker next to the SIM slot for the default Wi-Fi name, password, and admin login. Access Web UI: The ZTE MC801A is a powerful 5G router
Open a web browser and enter the default gateway IP (usually 192.168.0.1 192.168.1.1 Check Device Info:

If you are having trouble connecting devices, you can use the WPS button on the router to pair them automatically. Device Management: You can manage blocked devices through the Block List in the Wi-Fi settings menu of the web interface. Are you experiencing a specific connectivity issue
or a "Device Locked" error that led you to look into IMEI modification?
Changing or repairing the IMEI on a ZTE MC801A 5G router typically requires specialized software tools, as this unique 15-digit identifier is hardcoded into the device's hardware. While firmware updates generally do not alter the IMEI, specific "IMEI repair" programs can write new values to the device's Non-Volatile (NV) memory in cases of data corruption. Common Methods for IMEI Repair
Depending on the state of your device (e.g., IMEI showing as "0"), different technical approaches may be used:
ZTE Qualcomm Writer: This specialized utility can detect the device and use a "Write Only IMEI" function to restore a missing or corrupted number. Users typically need to back up their NV data before proceeding.
QPST and QXDM Professional: For advanced users, these Qualcomm diagnostic tools allow manual editing of NV items. By enabling a diagnostic port, you can navigate to specific NV Browser IDs (such as ID 1992) to input a new MEID or IMEI value.
Chimera Tool: This paid professional service software supports a "Repair IMEI" function for various mobile devices by patching the system. It requires an unlocked bootloader to execute the procedure. Legal and Technical Warnings
Modifying an IMEI is subject to strict regulations and technical risks:
Legal Restrictions: In many jurisdictions, tampering with an IMEI is illegal and can be prosecuted under fraud or telecommunications laws. For instance, it can attract significant fines or imprisonment in some regions.

I understand you're asking about changing the IMEI on a ZTE MC801A 5G router. However, I need to provide an important disclaimer first:
Disclaimer: Changing the IMEI of a device is illegal in many jurisdictions (including the US, EU, UK, and elsewhere) unless you are the manufacturer or a legally authorized repair center. IMEI alteration can be used for cloning stolen devices, evading network bans, or fraud. This response is for educational purposes only to explain why this is technically difficult and legally risky — not a guide to do it.
On Qualcomm-based devices, the IMEI is stored in the modem’s EFS (Encoded File System) – a proprietary, encrypted partition accessible only via diagnostic (DIAG) port using tools like QPST, QXDM, or AT+EGMR commands. However:
Some early batches of the MC801A had a hidden developer page. This door has been closed in recent firmware.
