IPv6 does not work. I would like a firmware that works IPv6

Oops, all the jewelry?

I have a problem with ONT HG8245Q2, it is not working IPv6, I tried to configure as described in the documentation.

Documentation Link: https://support.huawei.com/enterprise/en/doc/EDOC1100009119?idPath=24030884%7C9856746%7C23708797%7C22318691%7C21989531

I tried to check in other ways, but it doesn't work the way I try to put in the settings. I would like to get an ONT firmware that works with IPv6.

I have already tried downloading it from the link: https://support.huawei.com/enterprise/en/access-network/echolife-hg8245q2-pid-21989531/software

However, the message appears: No software found. For help, contact us.
