Samsung Galaxy Tab S8+ 5G (SM-X806B) Firmware Overview
What is the latest SM-X806B firmware?
X806BXXUBEZJ3, released October 15, 2026 with Android 16. It is a feature update on bootloader binary 11. The archive holds 87 official builds across 43 regions (CSC). Each one is the full stock ROM (flash file) for Odin, not an OTA patch.
Is the Samsung Galaxy Tab S8+ 5G still getting updates?
Yes. The newest build is from October 2026, and 24 of 43 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.
