LTEInspecteur (Windows): A powerful tool for monitoring signal quality (SINR, RSRP) and switching bands.

Huawei Band Tool: A simple script that works via the web browser console to reveal hidden menu options.

📌 Key Point: Always check your current Firmware Version under Advanced > System > Device Information before attempting any mods. If your version is 11.x.x.x, it is much harder to mod than version 10.x.x.x.

The custom UI shows live CA combos – e.g., "B3 (20MHz) + B7 (15MHz)". You can see exactly which towers and bands are aggregating for peak speed.

Stock firmware limits band selection to "Auto" or "4G Only." Custom firmware gives you a dropdown of all supported bands:

You can lock to B7+B3 aggregation for maximum throughput.

If you are a power user missing the advanced features of custom firmware (like VLAN tagging or advanced firewall rules), stop trying to make the Huawei do everything.
