git pillage when HEAD is not master

[andresriancho]

I'm trying to pillage a repository where the HEAD is not master, and it's not working.

Here are some obfuscated files, first .git/config

[core]
    repositoryformatversion = 0
    filemode = true
    bare = false
    logallrefupdates = true
[remote "origin"]
    fetch = +refs/heads/*:refs/remotes/origin/*
    url = git@github-server:raft/raft
[branch "staging"]
    remote = origin
    merge = refs/heads/staging

And then .git/HEAD

ref: refs/heads/staging

The thing is that when running, it won't download the files. For what I've been reading about the source code we need to change read the HEAD:

#2 - get static files
get "HEAD"

And right after parse it, and in the LOCAL repository change the HEAD to match the remote before continuing with the process.
