I've accidentally deleted a branch on my github repository.
I've searched up for a solution, and tried the methods mentioned here and here, but because I never merged that branch into master - I don't see it in the reflog at all.
My only local working copy that still has that branch on it is unreachable for few days because of technical issues.
Is there any way to recover that deleted branch?
The quickest way remains to write to GitHub support: they do have access to the refleg of the GitHub repo, and can restore that branch for you.
Then a simple fetch would allow you to recover that same branch in your local repo.
