Wait for the router to upload the file and reboot automatically. Do not unplug the device during this process. Troubleshooting Common Issues
One of the most user-friendly aspects of the utility is its ability to automate the most tedious parts of the process. The script can often automatically detect the correct router signature directly from the config.bin file using the signature.py script. Additionally, users can utilize the auto.py script, which attempts to try all known keys and configurations to decode the file with a single command. Furthermore, the utility provides a --try-all-known-keys parameter that systematically tests a built-in database of known keys against a user's config.bin . This is exceptionally useful for routers that use common or predictable keys.
He reached into his back pocket and pulled out a battered, unmarked USB drive. It was a dark grey plastic, scratched from years of use. On it, in fading silver Sharpie, were three words: ZTE Config Utility . Zte Config Utility

The project, which lives on GitHub, has roots in the reverse-engineering community. The core decoding work originated from a pastebin dump by a user named 'Felis-Sapien'. From that foundation, developers have expanded and refined the code, with major contributions from several maintainers.

This is the primary function of the utility. The core script, decode.py , is used to convert an encrypted binary configuration file ( config.bin ) into an editable, plain-text XML file ( config.xml ). The utility supports multiple payload types and version formats. It can handle type-0, type-2, type-3, and newer type-4 payloads and supports configuration files of different versions. Many routers have known keys that the utility can try automatically, making the process simpler for common models.
