Samsung Gear 2 NEO (SM-R381) Firmware Overview
What is the latest SM-R381 firmware?
R381XXU0BPK1, released November 15, 2016 with Android 2.2.1.2. It is a feature update on bootloader binary 0. The archive holds 20 official builds across 20 regions (CSC). Each one is the full stock ROM (flash file) for Odin, not an OTA patch.
Is the Samsung Gear 2 NEO still getting updates?
Most likely not: there has been no new firmware since November 2016, so Android 5.1.1 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-R381 builds in the archive run Android 2.2.1.2 to 5.1.1. The earliest build we have for each version:
- Android 5.1.1: R381XXU0BPH2 (Aug 2016), 1 build in total
- Android 2.2.1.2: R381XXU0BOA2 (Apr 2015), 19 builds in total
Can I downgrade the SM-R381 firmware?
Only to builds with the same bootloader binary (the Bit column) or higher. All decodable builds in the archive share binary 0:
- Binary 0 — since Mar 2014
