Have tested it severals times and had no problems.

If any problems please leave them in the comments below.
If you haven't done a backup before with TWRP then there won't be a folder for you to put this file in. Do a backup of your current Rom and then follow the steps above. This will give you the folders you need.
Phone Marker Folder: is a folder that the TWRP Recovery generates to store the backup in and is different with each phone.
This is what the folder should look like on the sdcard,
TWRP ----> Backup ----> Phone Marker folder ( Mine is HT43ASF08359, your might be different) Then the file you downloaded from me ----> 2014-04-20--10-11-12 KOT49H release-keys
If you just put the 2014-04-20--10-11-12 KOT49H release-keys file in the backup folder and not the Phone Marker folder then it won't show up when you go to restore the backup.
LINKS are live again!!!!!
