How to Install Android 4.3 JB ZCUANB6 on Galaxy S3 Neo+ GT-I9300I

Galaxy S3 Neo+ GT-I9300i is the focal point of our guide. This handset will receive something that shall make it worth the wait. More exactly: Android 4.3 Jelly Bean.

If you think the performance of your smartphone is in need of a boost, or you want more features, the new Jelly Bean will let you enjoy all of that and more. There will be new apps to install, customization options and so on. Apart from that, the upgrade can deliver goodies such as tweaks to make the battery last longer. The update won’t deliver major bugs and it gets rid of bloatware. But in order to have all of this at your disposal, you must use the Samsung GT-I9300i instead of another handset.

The upgrade can’t be possible without the presence of ZCUANB6 on your phone. Released last month for Bangladesh and this past February for India, the new firmware doesn’t sport an activated KIES logo. If you want an alternative to our tutorial, OTA is a good idea. But this alternative has to be selected only if your smartphone comes with stock ROM.

If rooted, your handset’s going to experience the following: an erased system partition. But that’s not all: the root access will become revoked. As soon as your phone’s updated to the Android 4.3 JB, you will still be able to use its internal / external SD cards and important files.Galaxy-S3-Neo-GT-I9300I
