A WS5200 bought in China runs firmware different from an EU or Latin American model. Users relocating overseas find that certain Wi-Fi channels (like 5GHz bands 100-140) are disabled, or the power output is capped below local maxima.

Rarely, a vulnerability in the bootloader allows unsigned code to run. For the WS5200, known exploits from 2019-2020 (like the "Huawei Enable Telnet" vulnerability) allowed temporary root access via special HTTP POST requests. But that is not a firmware update; it’s a runtime exploit that can be patched by newer official updates.
