Samsung W26 (SM-W9026) Firmware Overview
What is the latest SM-W9026 firmware?
W9026ZCS9BZI1, released September 22, 2026 with Android 16. It is a security update on bootloader binary 9. The archive holds 13 official builds across 1 region (CSC).
Is the Samsung W26 still getting updates?
Yes. The newest build is from September 2026.
Can I downgrade the SM-W9026 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 9:
- Binary 9 — since Aug 2026
- Binary 8 — since Jul 2026
- Binary 7 — since May 2026
- Binary 6 — since Mar 2026
- Binary 5 — since Feb 2026
- Binary 4 — since Jan 2026
- Binary 3 — since Nov 2025
- Binary 2 — since Oct 2025
A phone already on binary 9 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 9 build. How to read a build number.
