Samsung Galaxy W2018 (SM-W2018) Firmware Overview
What is the latest SM-W2018 firmware?
W2018ZCS3CUC1, released April 21, 2021 with Android 9. It is a security update on bootloader binary 3. The archive holds 20 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 W2018 still getting updates?
Most likely not: there has been no new firmware since April 2021, so Android 9 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-W2018 builds in the archive run Android 7.1.1 to 9. The earliest build we have for each version:
- Android 9: W2018ZCU2CSH3 (Aug 2019), 11 builds in total
- Android 8.1: W2018ZCU1BRL2 (Dec 2018), 4 builds in total
- Android 7.1.1: W2018ZCU1ARD1 (Apr 2018), 3 builds in total
Can I downgrade the SM-W2018 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 3:
- Binary 3 — since Nov 2019
- Binary 2 — since Mar 2019
- Binary 1 — since Dec 2017
A phone already on binary 3 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 3 build. How to read a build number.
