G925AUCU2AOF3 Over the air update on AT&T Galaxy S6 Edge, Not the 5.1.1 Update Yet

AT&T is also sending an update on Galaxy S6 Edge SM-G925A which will bump the firmware build version G925AUCU2AOF3. They have pushed the update along with the Galaxy S6 SM-G920A earlier but yet again this is not the Android 5.1.1 update but still in Android 5.0.2 base.  The latter brings various bug fixes, security protection improvements, and further enhancement to performance.

Here are the summarized technical details about the update addressed by Samsung and AT&T:
Effective July 9, 2015, AT&T will release a sofware update for the Samsung Galaxy S 6 edge (G925A). This update will be made available to customers via Firmware Over The Air (FOTA). A Wi-Fi connection is required for the update.
Software update includes
  • Find My Mobile and Reactivation Lock enhancements
  • Android OS security enhancements
  • Android version: 5.0.2
  • Baseband version: G925AUCU2AOF3
  • Kernel version: 3.10.61-4823236
  • Build number: LRX22G.G925AUCU2AOF3

They are sending the update out in waves from June 9th. The update files size is around 146MB,and it is now live via Over-The-Air OTA update. So if you don't get the notification, or you keep checking and it still says not available. You can now manually check the update by hitting your device Settings>About device>Software update>Check for update. Just make sure phone hasn’t been rooted nor modified so you can get the update without any hiccups. Noting that accepting  a OTA updates on a rooted device will breaks its root and if you are not lucky enough it may also results into undesirable soft-bricks.
