[How To] Get the Android 4.4 KitKat on AT&T Galaxy S4 SGH-I337

Page content:

We just know that the enthusiastic among you simply can’t wait for Samsung to release the Android 4.4 update — which will take lengthy 2-3 months from now — for your AT&T Galaxy S4, and that you would take every chance to install the KitKat OS update right away, if available.

Well, it is indeed available. And you can indeed take that chance. Right now!

Thanks to Google releasing the Android 4.4’s code, you already have the Gummy AOSP ROM (with the help of CyanogenMod team’s work) available for your AT&T Galaxy S4, model no. SGH-I337. Please don’t try this on any other phone with different model no.

Note: Gummy Android 4.4 ROM is not an official KitKat update for your Galaxy S4, btw. Only Nexus 5 is the phone running official builds of KitKat, and just today, Nexus 7 (2012 and 2013 edition) and Nexus 10 phones also started receiving it.

Bugs?

Well, no bugs. Everything seems to be working right away. Which is just great, considering most of the other device with Android 4.4 ROM have more than several bugs!

But, not all cool features have been incorporated right now, but that shouldn’t be far and you can expect all features to be mixed into ROM in next few updates.

Features (quoted):

* New base built from AOSP
* Status Bar Mods
* Theme Manager
* Hardware Key Mod
* Lock Screen Mod
* Many Wallpapers
* Performance Control
* Application Permission Controls
* Carrier Label Options
* Background Style
* Lock clock widget

Let’s see how to install the custom Android 4.4 KitKat update on your AT&T Galaxy S4.

WARNING!

Warranty may be void of your device if you follow the procedures given on this page.

You only are responsible for your device. We won’t be liable if any damage occurs to your device and/or its components.

CHECK DEVICE MODEL NO.

To make sure your device is eligible with this, you must first confirm its model no. in ‘About device’ option under Settings. Another way to confirm model no. is by looking for it on the packaging box of your device. It must be SGH-I337!

Do not use the procedures discussed here on any other Galaxy S4 (including the S4 devices at Verizon, T-Mobile, Sprint and international ones) or any other device of Samsung or any other company. You have been warned!

BEFORE YOU BEGIN..

You must do this pre-installation stuff before attempting to install the ROM on your Samsung Galaxy S4 SGH-I337 in order to avoid any complications later, and have a smooth and successful process.

BACK UP YOUR DEVICE

Back up important data and stuff before you start playing around here as there are chances you might lose your apps and app-data (app settings, game progress, etc.), and in rare case, files on the internal memory, too.

For help on Backup and Restore, check out our exclusive page on that linked right below.

ANDROID BACK UP AND RESTORE GUIDE: APPS AND TIPS

CHARGE YOUR DEVICE

If your android device powers off due to lack of battery while the process is underway, it could damage the device.

So, make sure your device is adequately charged — at least 50% battery of the device.

EXAMPLE VIDEO

If you haven’t used a custom recovery, either CWM or TWRP, before, to install a .zip file of a ROM on anything else, then we suggest you first watch a video of that, given right below, to get familiar with the process.

Just fyi, the video below shows installing a .zip file (of recovery) on Galaxy S3, but it doesn’t matter as the process remains exactly same. So, once you are finished with video, jump to downloads and step-by-step guide below.

Reminder: Before you proceed, make sure you’ve transferred the files you downloaded above to a separate folder on your Galaxy S4 phone.

STEP-BY-STEP GUIDE

Make sure you have backed up your phone adequately (including important data stored on internal memory). Also create a nandroid backup using your recovery for additional safety.

You’ll need either CWM or TWRP recovery for installing the CyanogenMod Android 4.4 KitKat ROM on your Galaxy S4 SGH-I337. And since CWM and TWRP recoveries function differently we’ve put together separate guides for both of them. So if you’re a CWM user, follow the CWM users guide and if you’re a TWRP user follow the guide for TWRP users.

NOTE:

Older versions of both CWM and TWRP recoveries are not working with Android 4.4 based ROMs, throwing installation errors and WiFi bugs, therefore you need to use the latest version of either recovery. We believe TWRP v2.6.3.x and above, and CWM v6.0.4.x and above are working fine with Android 4.4 ROMs.

Below is the link to latest CWM recovery for your AT&T Galaxy S4, that’s working fine with Android 4.4.

 GET LATEST CWM RECOVERY FOR AT&T GALAXY S4 (Android 4.4 compatible!)

GUIDE FOR CLOCKWORKMOD RECOVERY (CWM) USERS
  1. Boot into recovery mode. For this:
    • Power off your device and wait for 5-10 seconds until the device is fully switched off.
    • Press and hold  Volume Up + Home + Power buttons together and release them as soon as you see the Galaxy S4 logo.
      └ In Recovery mode, use Volume buttons to navigate Up and Down between options and use Power button to select an option.
  2. Create a Nandroid Backup from recovery. It’s optional but very important to do, so that in case something goes wrong you can restore to current status easily. For making a Nandroid Backup, go to Backup And Restore » Backup.
  3. Perform a Factory Reset (This will delete all apps and their settings and game progress). For this:
    • Select Wipe data/Factory reset, then select Yes on the next screen to confirm factory reset (screenshot)
  4. Install the ROM file first (Gummy-1.1-11-12-13-UNOFFICIAL-jflteatt.zip). For this:
    • Select Install zip » Choose zip from sdcard (or external sdcard, you know where your files are) » browse to the location where you saved the file and select the Gummy-1.1-11-12-13-UNOFFICIAL-jflteatt.zip » select Yes on next screen to confirm installation of the file.
      How to Flash File in CWM Recovery
  5. Now similarly flash the pa_gapps-full-4.4-20131111-signed.zip, as you did in step 4.
    └ Make sure to first flash the ROM file and then the Gapps file.
  6. Now, reboot your device. For this, go back to the main menu of recovery and select reboot system now.

Note: In case your device gets bootloop (stuck at logo while rebooting), just do a factory reset and you will be fine.

That’s all. Your phone will now reboot and it will take some time as it’ll be phone’s first boot after installing Android 4.4, be extremely excited for this!

      Reboot into recovery mode and do a factory reset. Check Step 3 in the guides above

      1. Ben says: Reply

        Did that, still in boot loop…

  2. Jk says: Reply

  3. Tim Desrochers says: Reply

    Worked perfectly. Thanks for your work.

    Excellent tutorial!

    Does this work with Baseband MF3?

  5. ScottLaRoc says: Reply

    Hi there Shivam,

    Can you tell me if this works on baseband I337UCUAMF3?

    Thanks!

    1. Shivam says: Reply

      Are there any known issues with the MF3 baseband that you’re worried about? If no, then just go ahead and install this ROM. It’ll work fine.

      1. ScottLaRoc says: Reply

        Yes, from what I heard when trying to install a custom rom on this baseband it could brick the device.

  6. Nathan Bain says: Reply

    Will this work with safestrap?

    1. Kapil says: Reply

      It should. Safetrap’s recovery version should be compatible. v2.6.3.0 and above for TWRP. v6.0.4.3 and above for CWM (ClockworkMod).

  7. JBW says: Reply

    Works great! It also fixed the bug in the stock 4.3 version with Wifi support of 802.11ac.

    1. JBW says: Reply

      Bug: HDR does not capture photo. It leaves a gray image.

  8. ScottLaRoc says: Reply

    After some research, if you have baseband version that ends in MF3, this will not work as the bootloader is locked. This will only work previous basebands, such as MDL. You can root the device but that’s about it. If you try to do this you may brick your device.
