Samsung Galaxy Tab S8+ 5G (SM-X806C) Firmware Overview
What is the latest SM-X806C firmware?
X806CZCUBEZJ3, released October 16, 2026 with Android 16. It is a feature update on bootloader binary 11. The archive holds 20 official builds across 1 region (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.
Which Android versions did it get?
The SM-X806C builds in the archive run Android 13 to 16. The earliest build we have for each version:
- Android 16: X806CZCU9EYJ4 (Oct 2025), 6 builds in total
- Android 15: X806CZCU9DYDC (Apr 2025), 3 builds in total
- Android 14: X806CZCU5CWK9 (Dec 2023), 8 builds in total
- Android 13: X806CZCU3BWC1 (Mar 2023), 3 builds in total
Can I downgrade the SM-X806C firmware?
Only to builds with the same bootloader binary (the Bit column) or higher. In the archive the binary of this model rose from 3 to 11:
- Binary 11 — since Aug 2026
- Binary 10 — since Feb 2026
- Binary 9 — since Nov 2024
- Binary 8 — since Jul 2024
- Binary 7 — since May 2024
- Binary 6 — since May 2024
- Binary 5 — since Aug 2023
- Binary 4 — since Apr 2023
- Binary 3 — since Mar 2023
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.
