Unfortunately SQL Server will not go backwards. The only way you can do this is Using SSIS to transfer the data or you can use the import/export utility.
On your 2012 Server Right click on the DB you want to export data from and scroll down to tasks and then choose export data it will have you then insert all of the information for both the source and destination servers then on the summary page click mappings and make sure they are correct for what you need and the DB it is going to is correct. Then follow the screens until you can click finish. YOu may have too play with it for a little bit to get it to behave nicely but this should work for you.
If all you have is a BAK file you may have to resotre it to a dummy DB on the 2012 server first.
