Samsung W25 (SM-W9025) Firmware Overview
What is the latest SM-W9025 firmware?
W9025ZCS4DZJ1, released October 17, 2026 with Android 16. It is a security update on bootloader binary 4. The archive holds 23 official builds across 1 region (CSC). Each one is the full stock ROM (flash file) for Odin, not an OTA patch.
Is the Samsung W25 still getting updates?
Yes. The newest build is from October 2026.
Which Android versions did it get?
The SM-W9025 builds in the archive run Android 14 to 16. The earliest build we have for each version:
- Android 16: W9025ZCU2CYI7 (Sep 2025), 16 builds in total
- Android 15: W9025ZCU2BYDB (Apr 2025), 5 builds in total
- Android 14: W9025ZCS2AYB1 (Feb 2025), 2 builds in total
Can I downgrade the SM-W9025 firmware?
Only to builds with the same bootloader binary (the Bit column) or higher. In the archive the binary of this model rose from 2 to 4:
- Binary 4 — since May 2026
- Binary 3 — since Feb 2026
- Binary 2 — since Feb 2025
A phone already on binary 4 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 4 build. How to read a build number.
