We recommend not following this guide if you have just recently found a software update coming to your device. Many of the new Android versions bring in new bootloaders and Chainfire needs to update the file to include a new recovery.img file that will unlock the bootloader again before the rooting will work. If you try rooting and the file is not updated, the Samsung Galaxy S4 Mini can fail to boot.
You will find the file in this guide automatically reflects those changes when they are made by Chainfire.
Are you experiencing a device that will not flash or is failing to boot? You should submit that information to Chainfire at the official CF-Auto-Root thread at XDA Developers.
- The rooting exploit found in this guide is based on Android 4.4.2 KOT49H.I9190UBUCNG1 firmware. You do not need to be running that build number to use the guide; however, you should be running Android 4.4.2 KitKat.
- You must be using the Samsung Galaxy S4 Mini with the model number GT-I9190 to use this guide. You can find out your S4 Mini’s model number by tapping on the Menu > Settings > About Device > Model Number.
BEFORE WE BEGIN
- Download the Samsung USB Drivers for mobile phones from the dot Tech USB Driver downloads page and install the drivers on your computer before you start this guide.
- Unlock the hidden Developer Options menu by tapping on the Menu > Settings > About Device > Tap the build number continuously until it says you are using the device as a developer — it’s usually about 7 or 8 times.
- Enable the USB Debugging Mode option from the Developer Options menu by tapping on the Menu > Settings > Developer Options > USB Debugging Mode.
- You are voiding the Samsung Galaxy S4 Mini warranty by following this guide.
- Make sure you backup the Samsung Galaxy S4 Mini if this is your first time rooting the device using Chainfire’s CF-Auto-Root tool. The package will be unlocking your bootloader before it applies the root and it will wipe your data if you haven’t had the bootloader unlocked before.
