This tutorial is for those of you with Loki’d unlocked bootloader on the AT&T SGH-i337 or Verizon SCH-i545, DO NOT FOLLOW THIS GUIDE IF YOU HAVE ANDROID 4.3 OR HIGHER ON AT&T OR VERIZON. If you already have CWM or TWRP recovery installed, that means you can follow this guide. If you have Safestrap recovery, that means your phone is on the locked bootloader so DO NOT FOLLOW THIS GUIDE!
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.
I know many of you have been asking me you want to update your phone to the latest stock firmware. Well, you can do that but on certain models like AT&T Galaxy S4, once you update your firmware to latest MF3, you can re-root it but you will lose the ability to flash CWM/TWRP recovery.
Also, using ODIN and stock firmware usually requires using a Windows computer and can be a long process sitting by your computer.
There’s some great news for AT&T or Verizon Galaxy S4 users, bootloader is not unlocked BUT we have LOKI method by XDA user DJrbliss that allows developers to bypass bootloader check to enable custom recoveries and custom ROMs.
