Samsung Galaxy CORE2 (SM-G3556D) Firmware Overview
What is the latest SM-G3556D firmware?
G3556DZNS1AQA1, released January 25, 2017 with Android 4.4.2. It is a security update on bootloader binary 1. The archive holds 6 official builds across 1 region (CSC). Each one is the full stock ROM (flash file) for Odin, not an OTA patch.
Is the Samsung Galaxy CORE2 still getting updates?
Most likely not: there has been no new firmware since January 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-G3556D firmware?
Only to builds with the same bootloader binary (the Bit column) or higher. All decodable builds in the archive share binary 1:
- Binary 1 — since May 2014
