How to Install Stock ROM Android 4.2.2 UCUAMDB on AT&T Galaxy S4 SGH-I337:

We recommend that you carefully follow ALL the steps to successfully flash your phone with Odin. Now let’s begin!

Step 1: First, you have to extract “I337UCUAMDB_I337ATTAMDB_ATT.zip” to a preferred folder (for example, in your downloads folder). You can extract the zip file using WinRAR or 7zip.

Step 2: Next, extract the Odin Tool zip file to a preferred folder.

Step 3: Run Odin Tool that you just extracted in the previous step.

Step 4: Load the Stock Firmware Odin Package you extracted in Step 1 into Odin Tool. To do this you will have to click on “PDA” and choose the .tar or .tgz file.

Step 5: Now, hold down Volume Down, Center Home, and Power buttons together until your phone enters into “Download Mode,” then release all buttons.

Note: If your device is not recognized by Odin then try to remove the battery for a while and put it back in again, and repeat Step 5.

Step 6: Next, press Volume Up button to continue.

Step 7: Once the phone displays “Downloading… Do Not Turn Off Target,” connect it to your computer using a good USB cable (preferably stock) and hit Start in Odin Tool.

Step 8: Now, set the phone in a good position where it will not become disconnected or disturbed and wait until the process is complete.

Note: You will see a word “PASS” in Odin, when the installation successfully completes. Let the phone automatically reboot (this will take longer than usual as it is the first time).
