Your index is corrupt when you see this error running usual git commands like git pull, git status, etc.:

error: bad index file sha1 signature
fatal: index file corrupt

Though it sounds bad, your changes are still there. Fix it by first removing the index file, then resetting the branch:

rm .git/index
git reset

You should be all good now.

To be safe, make a backup of .git/index before you delete it.
