The technical procedure for upgrading the Huawei B593, while straightforward, requires meticulous execution. Users typically have two methods: automatic over-the-air (OTA) updates initiated via the router’s web interface at 192.168.1.1 , or manual updates using a firmware file downloaded from Huawei’s official support portal or the specific mobile carrier’s website. The manual process involves several critical steps: first, backing up the current configuration settings to avoid losing custom APN (Access Point Name) profiles or port forwarding rules. Second, downloading the correct firmware version—a crucial point, as using firmware intended for a different regional variant (e.g., B593s-22 vs. B593u-12) can permanently brick the device. Third, performing the upgrade via the "System Tools" > "Firmware Upgrade" section while ensuring the device is powered via a stable mains connection and not through a PoE injector. Interrupting the power supply during the 3-5 minute flashing process can corrupt the router’s bootloader, turning it into an inoperable "paperweight."
