ISPs often bind your internet connection to the router's physical MAC. To swap routers without calling support:
While the native tool is best, here are alternatives if you cannot access it:

ZTE Config Utility (typically referring to the mkst/zte-config-utility
Python project) is a specialized tool used to decode and encode ZTE router configuration files (usually config.bin Zte Config Utility
). This is useful for advanced users wanting to retrieve lost passwords or modify hidden settings. 1. Prerequisites is installed on your system. The Utility : Download the source code from the official GitHub repository Config File : Obtain your router’s config.bin file, typically found in the web interface under Management & Diagnosis System Management User Configuration Management 2. Setup Instructions Extract Files : Unzip the downloaded repository into a folder. Install Dependencies
: Open a terminal or PowerShell window in that folder and run: pip install -r requirements.txt ``` Use code with caution. Copied to clipboard Prepare your Binary : Move your config.bin file into the utility's main folder or the directory. 3. Decoding the Config File To turn the encrypted file into a readable
file, use the following commands based on your router model: Auto-Decode (Recommended)
Attempts to identify the key automatically based on the router signature. ISPs often bind your internet connection to the
python3 examples/decode.py config.bin config.xml --try-all-known-keys ``` Use code with caution. Copied to clipboard Manual Decode (Using Serial & MAC) Required for newer models like the
. You will need the device's Serial Number and MAC address (found on the physical sticker). python examples/auto.py --serial "ZTEGXXXXXXXX" "xx:xx:xx:xx:xx" config.bin config.xml ``` Use code with caution. Copied to clipboard 4. Modifying and Re-encoding config.xml in a text editor to view or change settings (like the password). To save changes back to the router, encode the file again: python3 examples/encode.py config.xml config_new.bin ``` Use code with caution. Copied to clipboard config_new.bin back to your router via the web management interface. Important Notes
: The decryption key is often a combination of the ONT Serial Number (last 8 characters) and the MAC address. Compatibility
: Some newer firmware versions (post-October 2024) may have hardened encryption that is difficult to decrypt without specific AES keys. Are you looking to find a specific admin password or are you trying to enable Telnet on your device? If you want, I can:
