[Download in git in specific version.]

I tried the following:

git remote update
git fetch 
git checkout 11b255e0e9cd2541ddd0e7c314b440f59627d07d

I tried the Rathena folder. I received the following error:

error: pathspec '11b255e0e9cd2541ddd0e7c314b440f59627d07d' did not match any file(s) known to git.

Can someone help me?
