or unplug the LAN cable while the tool is running and the lights are blinking.

Official firmware locks the B593s22 to specific bands, disables Telnet/SSH, and restricts VPN passthrough. Community-developed OpenWrt or Padavan derivatives strip these restrictions. But flashing them requires bypassing signature checks. The toolexe accomplishes this by sending a raw binary that includes a modified header mimicking an official carrier image. The B593s22’s bootloader checks only the header’s size and basic CRC, not the cryptographic signature, when in multicast mode—a critical design oversight. b593s22 multicast upgrade toolexe

The Multicast Upgrade Tool is an official, low-level flashing utility developed by Huawei. Unlike standard upgrades performed through the router’s web dashboard (192.168.1.1), this executable tool bypasses the user interface entirely.

Once the router boots up successfully, log into the web admin page ( 192.168.1.1 or 192.168.8.1 ) and perform a factory reset to clear out any residual configurations from the old firmware.
