Samsung Galaxy Tab S8 5G (SM-X706C) Firmware Overview
What is the latest SM-X706C firmware?
X706CZCUBEZJ3, released October 22, 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-X706C builds in the archive run Android 13 to 16. The earliest build we have for each version:
- Android 16: X706CZCU9EYJ4 (Oct 2025), 6 builds in total
- Android 15: X706CZCU9DYDC (Apr 2025), 3 builds in total
- Android 14: X706CZCU5CWK9 (Dec 2023), 8 builds in total
- Android 13: X706CZCU3BWC1 (Mar 2023), 3 builds in total
Can I downgrade the SM-X706C 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.
