The ZTE MC801A is not a hacker-friendly device. The only “portable” firmware available is ZTE’s own generic release – which is safe enough if you follow instructions perfectly. But if you want true custom firmware, sell the MC801A and buy a router with OpenWrt support (like the Quectel RM520N-based units).

: Obtain the specific Stock Firmware ROM for your model. Flashing Procedure (Step-by-Step) 1. Hardware Connection

: Custom firmware or scripts (like the "ZTE MC801A signal script") allow users to lock the device to specific 5G bands (n78, n28, etc.), which is critical when moving the device between different locations or "portable" setups like campervans. 3. Common Risks and Issues

For the PC to flash the device, the router must be in EDL (Emergency Download) mode.
