I had a problem where my Samsung Galaxy S4 (SGH-I337M) was stuck in a boot loop because of the Lollipop 5.0.1 update. I tried everything from going into recovery mode and factory resetting it to doing the smack method on it. Then I found this way by flashing the Android Kitkat 4.4.2 ROM back into my phone via Odin. Here are the steps to downgrade to KitKat 4.4.2:

NOTE: I am not responsible for anything that happens to your phone. please proceed if you know what you are doing.

Before you start:
  • Turn on USB debugging by going to Settings>More>Developer Options. (If you don't have developer options, go to Settings>More>About device and press the build number 5-10 times and developer mode will be enabled)
  • Make sure battery is charged at least 50%
  • Backup everything if you can or make sure you have a backup already done.
  • Have your phone plugged into the computer
After you done those things, you ready to begin. Here is what to do:

1. Download Odin v3.09. You can download it by clicking the link. http://odindownload.com/

2. Download the firmware for your phone. Go to sammobile.com (You will have to create a free account first) and look up your model. (For Example: you will search SGH-I337M if you have a Canadian Galaxy S4). The Model info should be behind the battery. If you don’t know or can’t find it, comment below and I will find it for you. Make sure you have the right carrier as well if it says so.

NOTE: Downloading the firmware may take a while if you have a slow internet connection. If you have a slow internet connection, make sure your computer doesn't sleep overnight while its downloading. 

3. Extract both files to your computer.

4. Open Odin v3.09

5. On your Galaxy S4, Turn off your device. When its shut off, press the Power>Hone, and VOLUME DOWN key at the same time. You will see this pop up:[​IMG]

7. Click START. You will have to wait as the process takes 5-10 minutes. The phone will reboot once or twice. then the welcome screen should pop up. and you are DONE. You have successful downloaded Android KitKat 4.4.2.
