What you might want to try is to use a hex editor or equivalent to open up 'edits' and get rid of the last record. In all cases, the last record might not be complete so your namenode is not starting. Once you update your edits, start the namenode and run 'hadoop fsck /' to see if you have any corrupt files and fix/get rid of them. PS : Take a back up of dfs.name.dir before updating and playing around with it.

Maybe moving edits file and recreating a new one will work for you.
