Samsung Galaxy Tab Active5 (SM-X300) Firmware Overview
What is the latest SM-X300 firmware?
X300XXSEDZI1, released September 11, 2026 with Android 16. It is a security update on bootloader binary 14. The archive holds 34 official builds across 7 regions (CSC).
Is the Samsung Galaxy Tab Active5 still getting updates?
Yes. The newest build is from September 2026, and 7 of 7 regions already have a build from that month; the rest usually follow within a few weeks.
Can I downgrade the SM-X300 firmware?
Only to builds with the same bootloader binary (the Bit column) or higher. In the archive the binary of this model rose from 10 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 May 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.
