Now, after we have cleared the features aspect, we should consider in resolve and present other details related to the operation you are about to perform. The first to start with is the root access which is being required; else you cannot apply the Jelly Bean update on your Galaxy S3. Be aware because with the root access the warranty gets void. This is why you must follow a dedicated tutorial for ensuring that the S3 has an unchained system (you can use one of our step by step guides). If you will need to restore the warranty, you will have to downgrade to the stock ROM, or to update with an official software.

Then, you have to install a custom recovery image (like CWM recovery) on your SGS3. This tool must be used for installing the update and for making a full wipe of the system. Without completing the wipe, the Dragon ROM will not run properly on your phone. Therefore, if we talk about a wipe, we surely must talk about a backup. So, you should save all of your personal info which is being stored on the device internal storage memory, or else you will lose the same. For that, you have backup and restore guides explained here on Android.gs and by using the mentioned tutorials, you can learn how to save the current ROM, the EFS folder, the internet settings, the contacts, the text messages and much more.
