Samsung Galaxy Tab S10 Lite (SM-X406N) Firmware Overview
What is the latest SM-X406N firmware?
X406NKOU8DZJ6, released October 25, 2026 with Android 17. It is a feature update on bootloader binary 8. The archive holds 11 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 S10 Lite still getting updates?
Yes. The newest build is from October 2026.
Which Android versions did it get?
The SM-X406N builds in the archive run Android 15 to 17. The earliest build we have for each version:
- Android 17: X406NKOU8DZJ6 (Oct 2026), 1 build in total
- Android 16: X406NKOU1BYJ3 (Oct 2025), 8 builds in total
- Android 15: X406NKOU1AYG8 (Jul 2025), 1 build in total
Can I downgrade the SM-X406N firmware?
Only to builds with the same bootloader binary (the Bit column) or higher. In the archive the binary of this model rose from 1 to 8:
- Binary 8 — since Sep 2026
- Binary 7 — since Aug 2026
- Binary 6 — since Jul 2026
- Binary 5 — since Jun 2026
- Binary 4 — since Feb 2026
- Binary 3 — since Jan 2026
- Binary 2 — since Oct 2025
- Binary 1 — since Jul 2025
A phone already on binary 8 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 8 build. How to read a build number.
