Build date: 12 April, 2013
Galaxy S4 users who have already upgraded their handsets with Android 4.2.2 XXUAMDM Jelly Bean and are currently looking for a root method may follow our step-by-step guide. The tutorial uses CF-Auto-Root file released by recognised XDA developer, chainfire.
IBTimes UK reminds its readers that it will not be held responsible for any mishap. Before following the root guide, users are advised to verify that their devices meet the set of requirements.
1) Install USB Drivers for Samsung Galaxy S4 to transfer files between the Android device to the computer.
2) Enable USB Debugging Mode on the phone to connect it with the computer and use Android SDK with it. [Press Menu>> Settings>> Applications. From there navigate and click on Development option and ensure the USB Debugging Mode is turned on.]
3) As the tutorial might wipe out all data of the phone, create a backup. If the device is having custom recovery such as ClockworkMod/TWRP already installed then users are recommended to backup data using the recovery.
4) The Galaxy S4 should have above 80 per cent battery charge.
5) The device should be factory unlocked and not locked to a particular carrier.
6) Rooting the phone will void manufacturer's warranty. However, users can reclaim the warranty back by unrooting the device later.
7) The root file used in the guide works only on Samsung Galaxy S4 I9505. Applying this on any incorrect variant might brick the device. Therefore, verify the model number of the Galaxy S4 by navigating to Settings>> About phone.
