The Samsung Galaxy S4 was launched about 2 years ago. It seldom happens that an Android phone gets the latest OS upgrades after being so old but in the case of the Galaxy S4, it has happened. The phone started receiving the Android 5.0.1 Lollipop update just the closing week of February. Most of the S4 owners might have already grabbed the OTA or flashed the Lollipop firmware using Odin. In case you are still waiting for the new software update, you can install it manually by downloading the firmware from here and installing it using our tutorial.
Many people avoid receiving new updates for the fear of losing root access, especially when they are not sure if they would be able to root the device on the new version. Then there are people who would like to gain root if does not affect the warranty. In case you have just updated your Galaxy S4 GT-I9505 to the latest Android 5.0.1 and want to root it today we got a tutorial for the same. Tyxerakias from XDA has discovered a way to gain root on the Galaxy S4 running the Lollipop firmware without tripping the KNOX Warranty void counter. Since the method is a bit complicated, I’ll provide 2 methods: the first method is easier but it’ll trip KNOX and the second one is tougher but will keep KNOX counter at 0 x 0.
Method 1: Root Galaxy S4 and Install Recovery
Download the PhilZ recovery for your device: Download
Download the latest SuperSU package and copy it to your phone: Download
Download the Odin tool and unzip it: Odin_v3.09.zip
Download and install the Samsung USB drivers on your PC.
Enable USB Debugging on your Galaxy S4.
Now turn off your phone and boot it into the Download Mode by holding the Volume Down + Home + Power buttons together for 2-3 seconds. When you are prompted to press the Volume Up key, do it.
Now connect your Galaxy S4 to computer via USB cable.
Open Odin folder and launch the program as administrator.
Make sure the message box in Odin shows “Added!” text. If it doesn’t, reinstall the drivers, reboot the PC and the phone and connect it again.
Uncheck the Auto Reboot option on Odin (do not touch any other option).
Click the AP button on Odin and add the PhilZ recovery file with .tar extension.
Now click the Start button on Odin and wait till the installation is finished.
When you get PASS!/RESET! message on Odin, disconnect the USB cable.
Now long press the power button to turn off the device, or remove the back panel and pull out the battery for 20 seconds. Reinsert the battery and then hold theVolume Up + Home + Power keys simultaneously. When the screen turn up and you see the Samsung Logo, release the Power key. Keep the other two keys pressed until your phone boots into the recovery mode.
In PhilZ recovery menu, select Install zip option, navigate to the SuperSU update package (.zip file) and install it.
When you are done with installation, return to PhilZ main menu and select Reboot system now option.
Your Galaxy S4 will reboot now and when it boots up it will have root access.
