A niche community produces custom ZTE MF79U firmware builds. These often:
Pros: Better performance, advanced stats (RSRQ, CQI), full AT command access.
Cons: Brick risk, no support, may fail network operator certification.
If you choose this path, look for stable builds from reputable forums like 4pda, GSMHosting, or XDA Developers. Always have a backup of your stock firmware.

Before we discuss firmware, let’s quickly recap the hardware. The ZTE MF79U is a Category 4 LTE USB dongle supporting download speeds up to 150 Mbps and upload speeds up to 50 Mbps. It features a MicroSD card slot (up to 32GB), an external antenna port, and plug-and-play compatibility with Windows, macOS, and Linux.
However, like any networking device, its performance depends heavily on the ZTE MF79U firmware version installed. Firmware controls the modem’s radio parameters, USB driver negotiation, SIM card management, and web interface.
This process uses the ZTE Download Driver and Firmware Writer Tool.
The ZTE MF79U runs a capable but minimally secured firmware. While official updates have improved signature enforcement, many units in the field remain vulnerable to command injection and hardcoded credential attacks. Advanced users can customize the firmware via UART and repacked SquashFS, but must carefully handle partition integrity. For most enterprise environments, replacing the MF79U with a newer Cat6 or Cat12 device with proper TPM and signed update enforcement is advised.
