How to recover git repository accidentally deleted before committing anything

I decided to try GitHub for the first time and already managed to delete all my files in my most important project while playing around. Here is my console history:

git init
git remote add origin https://github.com/...
git add .
git config --global user.email (...)
git config --global user.name (...)
git reset --hard   // amazing move by me

I searched for many ways to recover this. One recommended was: git fsck --lost-found but it only returns:

missing tree 4b825dc642cb6eb9a060e54bf8d69288fbee4904
dangling tree 3178c349021f733a9fa7fa0fabd2ac34f8841bdd

and no blobs. So is there no hope to recover it?

That's odd, because missing tree and dangling tree cannot occur unless there are or were commits made. It's git write-tree that builds tree objects from the index (or git hash-object -w -t tree but this is hard to use). (Well, the missing tree is the empty tree—I thought that hash ID sounded familiar!—so that's a bit less odd.)

Still, however you got to this point, the dangling tree object is probably what has your blob hash IDs. Use git show or git ls-tree -r on it to get file names and blob hash IDs, then use git show or git cat-file -p on each blob ID to get the file's contents, and store those contents under the name you find in the tree.

Or, you can use eftshift0's trick: turn the dangling tree into the tree of a commit. That's even better / more convenient. (eftshift0 should turn this into an answer, which you should accept :-) )
