Samsung Firmware Downloader ( All Samsung Android Mobile Direct Download )
SamFirm Tool 0.3.6 Free Download
You can use it for all Samsung devices, but I have only tested it on Galaxy Tab S. It requires .NET Framework 3.5 (Microsoft Visual C++ 2008 Redistributable Package (x86) and Microsoft Visual C++ 2010 Redistributable Package (x86) installed)
If you run it via command line, you can use it to just decrypt .zip.enc2 and .zip.enc4 files.
Please let me know if the tool worked with your device and if you found any bugs (note, it's still beta).
