For those of you who want to root your AT&T SGH-i337 Galaxy S4, Verizon SCH-i545 Galaxy S4, or Galaxy S4 Active on Android 4.4.2, there’s finally a new root method that will root your S4. This root method also works on all Galaxy S4 models and does NOT trip Knox!
Towelroot also works on many other Android devices including Galaxy S3, Note 2, and most Samsung Galaxy devices. Towelroot is very safe to try so give it a try even if you don’t have Galaxy S4.
So, here’s how to do it, you do not need a Windows, Mac, or Linux computer!
After rooting, you can use SafeStrap Recovery to install custom ROMs!
Step 1. Make sure you have Android 4.4.2 in Settings->About phone.
Step 2. Open up a browser on your Galaxy S4 and go to TowelRoot.com. Press on the Lamda sign and it will download an APK file.
Step 3. Click on the APK file you just downloaded.
Step 4. Hit “Settings”.
Step 5. Hit “Unknown Sources”.
Step 6. Press “OK”.
Step 7. Press “Install” to install the towelroot app.
Step 8. Ignore the Google warning and press “Install anyway”.
Step 9. Press “OK” to open the Towelroot app.
Step 10. Press “make it ra1n”. Wait about 30 seconds and if your phone doesn’t reboot, try pressing “make it ra1n” again. If you see a force-close window, try force closing it by hitting “OK”. Your Galaxy S4 should have rebooted.
Step 11. Once rebooted, download the Superuser APK file and open it with MyFiles app. (Do not download from Play Store as the version is not the latest version!)
Step 12. Press “Settings”.
Step 13. Press “Unknown sources”.
Step 14. Pres “OK”.
Step 15. Press on “Install”.
Step 16. Hit “Open” to open the SuperSU app.
Step 17. Press on “Continue”.
Step 18. Press “Normal”.
Step 19. You will also get a message to disable/remove KNOX, make sure you hit “OK” as that will remove all KNOX apps which will interfere with your root if you don’t do it. (KNOX is an unnecessary, useless security app you DO NOT NEED, only interferes with root.)
Step 20. Now your Galaxy S4 should be fully rooted, go ahead and download any rooted app like Titanium Backup app and you should see SuperUser pop-up window like seen below.
Congratulations! You’ve successfully rooted your Galaxy S4 on Android 4.4.2!

What is a Custom ROM?
A custom ROM is a custom, modified operating system that you can install on your Android device. Basically it's like installing Windows OS on a Macbook. By installing a custom ROM, you can bypass stock factory settings like locked hotspot tether, install new Android versions early, or even convert your phone into another OS.
With a custom ROM, you can really maximize the capabilities of your smartphone by adding custom features that have been developed by open source developers.
How to Install Custom ROMs
First, you will need to root your device, if it is not rooted yet, follow our root tutorial and root your phone.
Once rooted, you should have TWRP installed on your phone. Installation of a custom ROM is easy if you learn the basic of it. If you don't know how to install custom ROMs using TWRP recovery, see our tutorial on How to Install Custom ROM using TWRP!
