Never attempt to flash firmware over a Wi-Fi connection. A momentary wireless drop will brick the device.
Conclusion Custom firmware on the Huawei HG658 v2 offers potential to regain control, add features, and improve privacy or functionality, but it is highly dependent on the device revision, proprietary drivers (especially DSL/Wi‑Fi), and bootloader constraints. Proceed with careful preparation: identify hardware, back up stock firmware, use serial access for safer recovery, and prefer hybrid or vendor-compatible methods when modem functionality must be preserved. If full modem support is required and unsupported by open firmware, consider using the HG658 in bridge/modem mode with a separate router running OpenWrt or another modern firmware.
The Huawei HG658 V2 is a venerable VDSL2/ADSL2+ modem router widely distributed by internet service providers (ISPs) across Europe, North Africa, and the Middle East.
