Hello, friend!
The HG8145V5 is a carrier product. The forum is oriented to enterprise products
Huawei ONT needs to be used with OLT and network management. The version must match the model. If the wrong version is used, ONT will not work.
Huawei ONT firmware involves information security and will not be released randomly.
If you need to download firmware/software, for your network security, please contact the operator or sales channel to obtain the correct ONT firmware/software.
For more information about the HG8145V5, click HG8145V5.
I hope I can help you!
Thanks!
