Samsung Gear S (SM-R750) Firmware Overview
What is the latest SM-R750 firmware?
R750XXU1BPK1, released November 18, 2016 with Android 6.0.1. It is a feature update on bootloader binary 1. The archive holds 20 official builds across 17 regions (CSC). Each one is the full stock ROM (flash file) for Odin, not an OTA patch.
Is the Samsung Gear S still getting updates?
Most likely not: there has been no new firmware since November 2016, so Android 6.0.1 is the last version this model got. The final builds below are still the best choice for a clean reinstall.
Which Android versions did it get?
The SM-R750 builds in the archive run Android 2.2.1.3 to 6.0.1. The earliest build we have for each version:
- Android 6.0.1: R750XXU2BPA1 (Jun 2016), 4 builds in total
- Android 4.4.4: R750XXU2BPF1 (Jun 2016), 2 builds in total
- Android 2.2.1.4: R750XXU2BOK1 (Mar 2016), 2 builds in total
- Android 2.2.1.3: R750XXU2BOL2 (Mar 2016), 9 builds in total
Can I downgrade the SM-R750 firmware?
Only to builds with the same bootloader binary (the Bit column) or higher. In the archive the binary of this model rose from 1 to 2:
- Binary 2 — since Jul 2015
- Binary 1 — since Oct 2014
A phone already on binary 2 rejects builds with a lower binary in Odin ("SW REV CHECK FAIL"), so it can go back to an earlier Android version only if that version has a binary 2 build. How to read a build number.
