Now the XDA developer community have come up with a new method to root your Samsung Galaxy S4 running the VRUAME7 update.
[NOTE] We do not recommend rooting your device unless you are well aware of the risks that come with it. Please note that your device can malfunction or you could loose data if you do not understand what you are doing, so proceed at your own risk.
[NOTE] If you happed to brick your phone, or come across any other issues you can download the original stock ROM from here and flash it onto your device using the ODIN program.
[NOTE] This method to rooting your device belongs to its developers who you can credit by following the source link at the end of this page.
[NOTE] This is a ROOT ONLY method. There is currently no way to unlock the bootloader. This means you wont be able to install a custom kernel or get Google Wallet to work
[NOTE] You also need a microSD memory card that is formatted by your PC as exFAT, not FAT32.
- Download and Install Samsung Official USB Drivers.
- Download and Install Android Terminal Emulator on your device.
- Download the extract the Root Exploit package on your computer.
Prepare your microSD card
- Insert a microSD into your device [REQUIRED]
- Make sure it is formatted as exFAT (not FAT32) [VERY IMPORTANT]
- If you have a 64GB microSD card you can use your phone to format it as exFAT by default directly from the Storage settings.
- If you have anything less than 64GB microSD card you may have to use the computer to format it manually as exFAT
[NOTE] If your microSD card is not formatted as exFAT you will see "permission denied" errors when running the exploit.
- Once formatted, move all files and folders from the Root Exploit package directly onto the root of your microSD card (nowhere else)
Rooting your device
- Open the Android Terminal Emulator app on your phone.
- Run the following 3 commands one after another (capital letters are important) cd /mnt/extSdCard
- After running the second command you should have seen your $ change to a # meaning you have root access.
- The third command is required to make this root access permanent.
- After all 3 commands are done, close the Terminal app and check if SuperSU has any update in the Play Store.
- Open SuperSU app and let the binary update itself to the latest (if any updates are available).
- Once complete, just open a root application and verify that is able to access root properly.
- Reboot your device one time and confirm you still have root acess.
- If all is well you should now be fully rooted on the stock VRUAME7 build of your phone
[NOTE] Make sure to avoid all future OTA's to prevent this root method from being patched.
