If you do not want to wait for the official update for your device, after rooting your respective device, you can install an unofficial ROM using recovery or, if you own a Samsung device, use ODIN to install the ROM.

How “easy” to do this work is to access the recovery mode (you might check the combination of keys for entering this mode on your device). You must have downloaded the ROM on the SD card and your ZIP mode mobile. In recovery mode, select the option “Install zip from sdcard” and when they finish the updates installed, choose the option to “Reboot System Now”. The device can take up to 15 minutes on again, so patience is necessary.

To install via ODIN, you need to have updated Phone Drivers. Once done, we can proceed to download and install ODIN and download the corresponding ROM, making sure that this model is consistent with our device, since ODIN, unlike KIES will not be satisfied if adequate and could harm your Mobile.
The next thing is to start the phone in download mode, so you need to check the key combination that allow access to this mode in your device. Once done, connect your device to the PC, where it is already started and this will be recognized by ODIN, allowing us to install the ROM that you downloaded. By clicking on the button pda in ODIN main screen and select the tar file containing the ROM you want to download. Make sure that the options repartition, delete partition efs and update partition boot are unchecked before clicking Start.
Once the process starts you can not stop, as the device may become unusable. ODIN screen will show the progress bar of the installation until the device is finally ready for use.
However, as the procedure for each phone ROMs can have differences, we suggest searching the web, specifically how to do it with your phone to avoid making mistakes as a general process that explained above. Good Luck! 🙂
