If you are attempting to flash the device to "generic" firmware to unlock features, proceed with extreme caution.
While advanced users often seek "unlocked" firmware to enable features like bridge mode, static routing, or telnet access, there are significant risks:

Q: Does the LG8245X6 support bridge mode in the latest firmware? A: Yes, but many ISP builds hide it. Stock Huawei firmware (V500R019C20S135+) has a clear “Bridge WAN” option. If yours is locked, you need to ask your ISP to switch the ONT to bridge mode remotely. huawei lg8245x6 firmware

Q: Will updating firmware unlock 2.5GbE ports? A: No. The LG8245X6 hardware has a standard 1GbE switch. No software can change the physical PHY limitation. If you are attempting to flash the device
