How-To: Install CWM Recovery On An AT&T Samsung Galaxy S4 SGH-I337 And Root It

Last updated: October 2, 2018.

Install CWM Recovery On An AT&T Samsung Galaxy S4

The AT&T version of the Samsung Galaxy S4, the Galaxy S4 SGH-I337, has gotten an update to Android 4.4.2 KitKat.  If you’ve have this update in your device, you will have lost any previous custom recoveries you installed and also no longer have root access.

The CF-Auto root method can root the AT&T Samsung Galaxy S4, but CF-Auto root will not support custom recovery anymore.  To install recovery, you are going to need to use the Odin or Loki method but these can be complicated.  We’ve found an easier way.

In this guide, we’re going to show you our way to install custom recovery and root a Samsung Galaxy S4 SGH-I337 that runs Android 4.4.2 KitKat.

Prepare your phone:

  1. Make sure that your phone is a Samsung Galaxy S4 SGH-I337. Check by going to Setting>About
  2. Make sure that your phone runs Android 4.4.2 KitKat
  3. Backup all your important messages, contacts and call logs.
  4. Make a backup of the phone’s EFS data.
  5. Unlock your phone’s bootloader.
  6. Download USB drivers for Samsung

Note: The methods needed to flash custom recoveries, roms and to root your phone can result in bricking your device.  Rooting your device will also void the warranty and it will no longer be eligible for free device services from manufacturers or warranty providers.  Be responsible and keep these in mind before you decide to proceed on your own responsibility.  In case a mishap occurs, we or the device manufacturers should never be held responsible.
