Samsung Galaxy Tab S8+ 5G (SM-X806B) Firmware Overview
What is the latest SM-X806B firmware?
X806BXXSBEZH3, released August 18, 2026 with Android 16. It is a security update on bootloader binary 11. The archive holds 63 official builds across 40 regions (CSC).
Is the Samsung Galaxy Tab S8+ 5G still getting updates?
Yes. The newest build is from August 2026, and 21 of 40 regions already have a build from that month; the rest usually follow within a few weeks.
Can I downgrade the SM-X806B 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 May 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.
