Samsung Galaxy Tab S10 Lite (SM-X406B) Firmware Overview
What is the latest SM-X406B firmware?
X406BXXS8CZI2, released September 12, 2026 for region BVO with Android 16. It is a security update on bootloader binary 8. The archive holds 5 official builds for this region.
Is the Samsung Galaxy Tab S10 Lite still getting updates?
Yes. The newest build is from September 2026.
Can I downgrade the SM-X406B 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 8:
- Binary 8 — since Sep 2026
- Binary 7 — since Aug 2026
- Binary 6 — since Jul 2026
- Binary 4 — since Feb 2026
- Binary 3 — since Jan 2026
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.
