What is the latest SM-W9025 firmware?
W9025ZCS4DZI1, released September 19, 2026 with Android 16. It is a security update on bootloader binary 4. The archive holds 21 official builds across 1 region (CSC).
Is the Samsung W25 still getting updates?
Yes. The newest build is from September 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), 15 builds in total
- Android 15: W9025ZCU2BYDB (Apr 2025), 4 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.
