Samsung Galaxy Tab S8 Ultra (SM-X900) Firmware Overview
What is the latest SM-X900 firmware?
X900ZCSBEZH3, released August 19, 2026 with Android 16. It is a security update on bootloader binary 11. The archive holds 38 official builds across 18 regions (CSC).
Is the Samsung Galaxy Tab S8 Ultra still getting updates?
Yes. The newest build is from August 2026, and 18 of 18 regions already have a build from that month; the rest usually follow within a few weeks.
Can I downgrade the SM-X900 firmware?
Only to builds with the same bootloader binary (the Bit column) or higher. In the archive the binary of this model rose from 10 to 11:
- Binary 11 — since May 2026
- Binary 10 — since Feb 2026
A phone already on binary 11 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 11 build. How to read a build number.
