The Samsung Galaxy S4 can now be anytime installed with official XXUGNI2 Android 4.4.2 firmware. The new Android firmware has already begun rolling out OTA and many of you are running it already. That brings me to my first point: don’t start using the steps listed below unless you are running this firmware. You see, each new release comes with patches issued by the Google and Android developers for fixing the exploits found in past builds. That means the developers focusing on opening the OS up must find other exploits from the new build. That’s why they are always specific. You can check the build you are running now by turning the smartphone on and stopping over at the Settings > About Device and taking a look.
We know Android 5.0 Lollipop is rolling now for all the Google nexus range of smartphones and tablet. Additionally, the Motorola company has a couple of releases. We still haven’t seen any Samsung Galaxy releases. Since the S4 isn’t new in the Galaxy range, that means it’s still a while away from any of the latest candy love with material Design UI. Why do I mention that? Because it means there’s every reasons to update to the XXUGNI2 build and find root access. Sometimes owners think it’s more effort than it’s worth. However, it’s still months away from Lollipop. If you want to unlock the system internals away from the default factory restrictions so that way you can install custom ROMs or custom firmware.
A good idea will be to check the USB charging is working. Most modern-day smartphones come with USB charging as s stock feature. That means when it’s plugged into the computer of choice, it starts charging the battery all by itself. It charges slower than a traditional battery charger, but you’ll notice the battery going up and not downwards nonetheless. So, if we are plugging into a computer for most of the guide there’s no point worrying about the battery level so long as you know the USB charging is working. You want to reserve at least 50% battery power before starting if you know it’s not working. That way you’ll get through the guide in its entirety and it won’t shut down. Making sure the handset doesn’t turn off is vitally important since shutdowns often lead to bricking. We must see through the flashing process before we can reboot and load it with the new unchained operating system.
Furthermore, you ought to use a Windows PC since we are using the Odin application. Odin is specifically made for Windows PCs and does not work with mac or Linux. You can flash firmware by using different tools, but you can’t root using Chainfire’s tools.
Nothing during the steps expects to wipe the data from the phone. However, you never know what is going to happen with technology. It’s best practice to back up the data stored on the phone so that way you don’t lose it if something happens. Backup the phone contacts, call logs, SMS texts, videos, music files, audio files, pictures and EFS folder. The EFS folder is essential for rooting since if corrupt you’ll get in trouble.
For accomplishing this root process, first you must download the Cf-Auto-root tool on a computer or laptop. It doesn’t matter if it’s a small notebook, as long as it has the USB slot in the side so we can connect our phones. As you know, to successfully connect to the computer with the phone, first we must install the up-to-date USB drivers. Numerous people already have them working. You can always test yours by plugging in and heading over to “My Computer” and clicking on the phones drive. If you can get access to the data from the computer you know the drivers are already working fine. If not it’s time to head over to the official website and grab your file. Alternatively you can install Samsung Kies and install the drivers automatically from there. Just remember to disable Kies before starting the guide since it interferes with the Odin app.
Correspondingly, another program that interfere with Odin is the security on the computer and Android device. Therefore you ought to disable both of them until leaving here. Remember to turn them back on again before you start browsing the web or else you can find viruses.
If you get stuck in a continuous boot loop, first you must attempt wiping the cache. Select “wipe data factory reset” and “wipe cache partition” after entering recovery mode. If that doesn’t work you ought to try a factory reset. A factory reset wipes the data clean as if it’s brand new. That’s why you should always backup the data just as we suggest.
Lastly, you want to stopover at the Developer options menu where you must enable USB Debugging mode. The mode is essential for connecting to the computer. If something isn’t working during the steps it’s likely for this reason or the drivers. That’s where you want to look if you need help.
