Samsung Galaxy Tab A11 LTE (SM-X133) Firmware Overview
What is the latest SM-X133 firmware?
X133DXS5BZI3, released September 18, 2026 with Android 16. It is a security update on bootloader binary 5. The archive holds 22 official builds across 15 regions (CSC). Each one is the full stock ROM (flash file) for Odin, not an OTA patch.
Is the Samsung Galaxy Tab A11 LTE still getting updates?
Yes. The newest build is from September 2026, and 15 of 15 regions already have a build from that month; the rest usually follow within a few weeks.
Can I downgrade the SM-X133 firmware?
Only to builds with the same bootloader binary (the Bit column) or higher. In the archive the binary of this model rose from 4 to 5:
- Binary 5 — since Sep 2026
- Binary 4 — since Aug 2026
A phone already on binary 5 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 5 build. How to read a build number.
