Samsung Galaxy Tab S10 Lite (SM-X406B) Firmware Overview
What is the latest SM-X406B firmware?
X406BXXS4BZB7, released March 11, 2026 for region INS with Android 16. It is a security update on bootloader binary 4. The archive holds 2 official builds for this region.
Is the Samsung Galaxy Tab S10 Lite still getting updates?
The last build arrived in March 2026. Updates have slowed down — models late in their support period move to quarterly or half-yearly security patches before they stop.
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 4:
- Binary 4 — since Feb 2026
- Binary 3 — since Jan 2026
A phone already on binary 4 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 4 build. How to read a build number.
