How To Root Galaxy S4 GT-I9505 On Android 4.2.2

0
Galaxy S4 rooted! No, this one actually works! Earlier, news hit the internet that the Samsung Galaxy S4 had been rooted, and I was almost tempted to break the news too when I saw the forum thread at XDA-Developers. However, news as it was, it was always going to be a risk asking our readers to hop onto the root bandwagon, owing to the fact that the developer had no device to test the method on. That’s when recognized Android developer and XDA forum member ‘Chainfire’ stepped in to save the day and confirm root access!

The rooting method for the Galaxy series has always been the same, till the release of the S4. Apparently, this time around, repacking Samsung’s firmware package with su to flash it via ODIN is causing the device to reboot every time the su binary is executed. This is because of the new Samsung Knox security feature that makes phones eligible for workplaces that use the ’Bring Your Own Device’ (BYOD) policy for their employees.

The working method, the one we’ll be discussing here, is none other than the famous CF-Auto-Root process by Chainfire, that still seems to be working for the GT-I9505 (Qualcomm LTE) version of the S4, but not the Exynos 5 variant. Be sure that your GT-I9505 is running the XXUAMD2 firmware. It’s the firmware this method was tested on, but as Chainfire points out, it might not be the one that is shipped with the final release.

Disclaimer: This root mechanism works only on Samsung Galaxy S4 LTE GT-I9505, with the firmware XXUAMD2. All other variants and firmware versions are unsupported. Please follow these instructions at your own risk. Whilst being safe and coming from a renowned developer, we do not take any responsibility for any damage happening to your device as a result of following this procedure.

Requirements:
GT-I9505 Samsung Galaxy S4 with firmware XXUAMD2
Chainfire Auto-Root package
Odin3 Flash Utility
At least 50% battery remaining on your device
USB Drivers configured for your Galaxy S4

Step 1: To begin, download the root package and unzip to a convenient location.

Step 2: Put your Samsung Galaxy S4 in Download mode using the button combination. To do so, turn the phone off, then hold down the Volume Down, Home and Power buttons together to boot it back up. As soon as the phone boots, release the power button and follow any on-screen instructions that might appear.

Step 3: Launch Odin3 on your computer, and connect your device in download mode to the PC using USB cable. Odin3 will detect the connection and indicate a COM port on top.

Step 4: Under PDA, select the .tar.md5 file that you extracted from Chainfire Auto-Root package. Make sure that Re-Partition is unchecked, and don’t touch any other settings. Hit the Start button to begin flashing the new PDA.

Step 5: Once flash is completed, the device will automatically reboot with a red Android logo, after which you’ll have root access.

Step 6: If the boot happens without the red Android, manually reboot into recovery to initiate the process, and you’re good to go.

That’s it – enjoy root access on your Samsung Galaxy S4 LTE GT-I9505!
