Firmware exclusive - Hg6145d2

1. What is the Hg6145d2?

The Hg6145d2 is a fiber optic gateway (ONT/ONU + router combo) commonly provided by internet service providers (ISPs) like Vodafone, Deutsche Telekom, Proximus, and others in Europe and Asia. It is manufactured by Huawei (hence the "HG" prefix).

Key features:

GPON / XGS-PON capable
4 Gigabit Ethernet ports
2 POTS (telephone) ports
Dual-band Wi-Fi (2.4 GHz & 5 GHz)
USB port for sharing storage/printers
TR-069 remote management (ISP control)

Issue 2: Firmware update stuck at 50% or 99%

Cause: Corrupted flash partition or bad TFTP transfer.
Solution: Power cycle the modem. Hold the reset button while powering on for 15 seconds until only the power LED blinks. This enters PXF recovery mode, which forces a fresh firmware pull from the ISP.
