You can also Make it work your L Model with the following instructions:
1-Root your Non-signal 8160L.
2-extract this and copy all folder to your SD Card tee.rar
3-Install Root explorer.
4-Using Root Explorer Go To System/Lib and locate "Tee" Folder and delete it. It should be at the end of the lib folder.
5-Put Your extracted folder on System/Lib and set permissions to rwxr-xr-x.
If Root explorer dont let you delete Tee Folder, remember to mount system files as R/W And not R/O
This method works on 8160L GA flashed with any 8160 Stock and Custom Firmware, Tested by Myself.
Glad i can help
