Samsung Galaxy Core 2 DUOS (SM-G355M) Firmware Overview
What is the latest SM-G355M firmware?
G355MUBS0AQC2, released July 12, 2017 with Android 4.4.2. It is a security update on bootloader binary 0. The archive holds 20 official builds across 18 regions (CSC). Each one is the full stock ROM (flash file) for Odin, not an OTA patch.
Is the Samsung Galaxy Core 2 DUOS still getting updates?
Most likely not: there has been no new firmware since July 2017, so Android 4.4.2 is the last version this model got. The final builds below are still the best choice for a clean reinstall.
Can I downgrade the SM-G355M 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 Jun 2014
