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). Each one is the full stock ROM (flash file) for Odin, not an OTA patch.
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.
