Samsung Galaxy Tab Active5 5G (SM-X306B) Firmware Overview
What is the latest SM-X306B firmware?
X306BXXSEDZI1, released September 10, 2026 with Android 16. It is a security update on bootloader binary 14. The archive holds 151 official builds across 34 regions (CSC).
Is the Samsung Galaxy Tab Active5 5G still getting updates?
Yes. The newest build is from September 2026, and 21 of 34 regions already have a build from that month; the rest usually follow within a few weeks.
Can I downgrade the SM-X306B firmware?
Only to builds with the same bootloader binary (the Bit column) or higher. In the archive the binary of this model rose from 9 to 14:
- Binary 14 — since Sep 2026
- Binary 13 — since Aug 2026
- Binary 12 — since Jul 2026
- Binary 11 — since Jun 2026
- Binary 10 — since Feb 2026
- Binary 9 — since Jan 2026
A phone already on binary 14 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 14 build. How to read a build number.
