How to get a gitub fork that i bought?

first of all,thanks to epic for their epic announcement,which made me to come back and rethink about ue4.

the problem is that when i subscribed to ue4 ,i only just downloaded binary version of ue4.
did not do any fork from git repo?
so after the subscription expired i lost my that opportunity ?

but now i want to get back to track and start to submit 2 pull request.
so how to get a fork from git repo ?
i bought it on January.
so most probably i have the right for v4.6.1

Did you set up typed in GitHub user name in your UE4 profile in page?

Hi

As we develop UE4 and build on the previous code, some versions become phased out as they were not complete “release builds”. The released builds are still listed (4.6.1, etc) on github, but some of the “in-between” builds were removed as they became obsolete (promotable builds for instance). If you did not fork those builds, then they are no longer available.

If you can give me some more details, maybe I can help you find what you are looking for.

Thanks!

here is my gitHub ACCOUNT:

i just want to submit 2 pull request.
one for the bug that i found in device manager .it happens only for non brand chiness android devices.
and another one for a code integration which will help others to integrate several projects all together by one click.

that’s it.
how to submit that pull request from my situation?
