Sprint Galaxy S6 OTA Update to Lollipop version 5.1.1 G920PVPU2BOF7 Officially Rolling

Sprint Galaxy S6 Android 5.1.1 Lollipop OTA update has just officially released. The Android 5.1.1 update will now bumps the build version to G920PVPU2BOF7 of which replace the before Android 5.0.2 G920PVPU1AOE2.  The latter brings the OEM unlocking feature which is similar to T-Mobile's Galaxy S6 update recently.  Along with the 5.1.1 update are for the device stability improvements, bug fixes and further enhancements to performance.

The OEM unlocking is basically the so-called "boot loader unlocking"  it the new Anti-theft features that holds the Factory Reset Protection in the device.  Sprint Galaxy S6 doesn't typically have a locked boot loader like AT&T, Verizon.  So the lock boot loader features somehow optional to the user. This protects the device from someone and prevent people from  installing a custom recovery, wiping your device. So this should not be an issue with Sprint if the boot loader is not locked.

The update is now live via Over-The-Air and weighs around 563 MB in file size.

Model number: SM-G920P
Android version: 5.1.1
Baseband version: G920PVPU2BOF7
Kernel version: 3.10.61

How to Update the Galaxy S6 to Lollipop 5.1.1 via Firmware Over-The-Air (OTA)

This is the usual method on how to check and to perform an update on Galaxy S6 and S6 Edge to the latest software version.  This method is what we called Firmware Update  Over-The-Air and so-called as FOTA or simply OTA update. In most often cases a notification message will directly sent to you by your network provider and by Samsung itself, telling you that there is a new update that has now available for download.  This approach requires you to prepare a strong WiFi connection,  and so it might happened sometimes that one did not receive any software update notification messages; 1) if and when the device is out of range during the software update roll out  period, 2) Automatic update has been turned off in the device Settings.
However, We can still manually check for the update instead.
Here’s how to do it manually:
  • From your Galaxy S6 Home screen tap on Apps.
  • Select the Settings gear icon.
  • Tap About device.
  • Tap Software update.
  • Tap Check for update.

It will then notify you that a new update is available for download. But it also says that “Your device software is up to date“, and there is no software update is yet available for grab. You can simply choose Download and Install now if you do so or else Install later if you want to get the update in later time.

But if ever you might have had receive this message while checking software update that says something like “The operating system on your device has been modified in an unauthorized way. Try downloading software updates using Smart Switch on your computer or visit a customer service center.”  This is a warning message that only appears for those devices that has been rooted and installed with modified and unofficial firmware.  So to be able to get the Software OTA update again, you must Unroot your Galaxy S6 first and removed any modification that has been installed on it.

It will then automatically tells you that a new update is available or your software is up to date when there is none yet.
