fatal: your current branch appears to be broken

问题

I give this error when I use

 git log

fatal: your current branch appears to be broken

my branch file was broked I opened .git/refs/heads/mybranch in notepad but I see only some ????????? in file

I know I must find branch hash and copy that into .git/refs/heads/mybranch file but I don't how to find that hash

I read this topic Broken branch in git, fatal: your current branch appears to be broken

回答1:

finally, after very pain, this worked for me

1 get back up from your .git directory
2 open file .git\logs\refs\heads\<branch name> with your editor 
3 copy second hash of your last line
4 open file .git\refs\heads\<branch name> and delete everything in this file
5 past that hash to .git\refs\heads\<branch name>
