AT&T Galaxy S5 Active G870A Stock 4.4.2 G870AUCU1ANE4 Firmware

Here is the first Android 4.4.2 KitKat Stock Firmware for AT&T's Samsung Galaxy S5 Active  (SM-G870). The stock firmware will be useful just in-case when the time comes that you might want to return back your Samsung Galaxy S5 Active  SM-G870 to it's official firmware. The stock firmware can wipe root or any customization that you may wish to be completely remove from your phone.

Once your phone has been modified, it also proven essential to use the stock firmware if you cannot receive any OTA update anymore  Some advanced user have had used the stock firmware if they have messed-up from customization and resulted into bricks, so the stock firmware is also best for fixing unwanted soft-bricks, bootloops or just stuck on a welcome screen logo.

So like I said, use of the stock firmware is for AT&T's Galaxy S5 Active G870A advanced users only.  This cannot be used and is not recommended  by any of those who did not know how the stock firmware works.

- Stock ROM packages comes in two formats the ‘Full-Wipe’ (delete your stored data after flashing) and the ‘Non-Wipe’ (it doesn’t delete your phone’s stored data) but it is highly recommended to make a back up all important files stored from your phone’s internal memory – contacts, messages, etc.  before flashing no-matter if it is Full-WIpe or Non-Wipe,  just to be safe and ensure that your stored data are in  safe  if something went wrong during the flashing process.
- Use a PC or laptop that runs in Windows OS, with a good and perfectly working USB serial port.  Odin will not work on MAC OS.
- Use the supplied USB cable for your Galaxy S5.
- Enable USB debugging from your phone’s settings. Go to Settings > About device > Look for the build number, and tick that  build number for 7-times until a pop-up message says‘Congratulations you are now a developer’ .
