Samsung Galaxy Tab S8 Ultra 5G (SM-X906B) Firmware Overview
What is the latest SM-X906B firmware?
X906BXXSBEZH3, released August 19, 2026 with Android 16. It is a security update on bootloader binary 11. The archive holds 65 official builds across 37 regions (CSC).
Is the Samsung Galaxy Tab S8 Ultra 5G still getting updates?
Yes. The newest build is from August 2026, and 24 of 37 regions already have a build from that month; the rest usually follow within a few weeks.
Can I downgrade the SM-X906B firmware?
Only to builds with the same bootloader binary (the Bit column) or higher. In the archive the binary of this model rose from 9 to 11:
- Binary 11 — since Jun 2026
- Binary 10 — since Feb 2026
- Binary 9 — since Jan 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.
