AT&T Galaxy S4 active updated to Android 5.0 Lollipop and root still possible

Introduced in mid-2013, the Galaxy S4 active is the first Samsung’s IP67 certified Android smartphones. It’s released soon after the original flagship phone – Galaxy S4 and it’s designed for those who have active outdoor activities. Loaded with Android 4.2.2 (Jelly Bean) when released to the public, Samsung finally rolled out the Android 5.0 Lollipop update for AT&T variants (SGH-i537) of the phone with I537UCUCOC6 software version. For those who have been rooted, you still have a chance to regain root on Lollipop (OC6) for AT&T Galaxy S4 active with the help of the FlashFire app.

 

The Lollipop updates become available via OTA update, when looked at from its file size (974MB – 1.0GB), it’s a huge update and will bring significant changes to the phones. As we know, the Android 5.0 brings significant improvements over KitKat. You will experience the Google-powered material design in TouchWiz User Interface (UI) and also fluid motions. In addition, you can also expect a better battery life with improved battery saving features.

Regarding superuser privileges, you still have a chance to regain root on Lollipop updates (I537UCUCOC6) for AT&T Galaxy S4 active, only when you’re running KitKat at the moment and still have working root access. Thanks to muniz_ri from xda who found a method to manually update to rooted Lollipop firmware by using FlashFire app by Chainfire.
