– Daydream (Settings>Display)
– New Additions in Notification Center

We have repackaged this firmware into an ODIN Flashable firmware ourselves from the dump files we took from Saturn’s device. This firmware will increase your binary counter, if you don’t know what this means then don’t flash this firmware. This Firmware will also change your device status to Modified. This firmware doesn’t contain any Modem so the Modem you are using before flashing this firmware will remain. This is a PRE-RELEASE version so not official from KIES. As this is a PRE-RELEASE firmware some minor bugs are to expect.
We have FULLY TESTED this firmware and this firmware works perfectly as any other official firmware.
Android Version: 4.2.1 – JOP40D (Jelly Bean)
Region: Middle East
Build Date: 19th February 2013
