Samsung’s been very of late updating its device with Reactivation lock-toting updates, and the latest device of the company to receive the same update is Sprint Galaxy S5. The update is based on Android 5.0.2 only, and goes by the build no. G900PVPU3BOF6, or OF6 in short, which is ironically the same 3 set of characters that brought the Android 5.1 update to T-Mobile Galaxy S6 and Galaxy S5 users.

Anyhoo, for what it’s worth, a TAR of the firmware is available, which you can flash using Odin PC software. So, if OTA fails you, you have a way out.
