The V300R13C10SPC800 tool is compatible with every Huawei ONT. It works best on older models such as the HG8321R, HG8346R, HG8145C, and SA1456. On newer devices with firmware versions like V5R020C10S213 , the tool may fail to open telnet. In those cases, you might need a more recent tool such as V500R19C00 or a “V3‑V5” combined utility. rewritev300r13c10spc800exe
