Samsung Galaxy Tab S11 5G (SM-X736B) Firmware

Samsung Galaxy Tab S11 5G (SM-X736B) Firmware Overview

What is the latest SM-X736B firmware?

X736BXXU9CZJ7, released October 31, 2026 with Android 17. It is a feature update on bootloader binary 9. The archive holds 107 official builds across 43 regions (CSC). Each one is the full stock ROM (flash file) for Odin, not an OTA patch.

Is the Samsung Galaxy Tab S11 5G still getting updates?

Yes. The newest build is from October 2026, and 21 of 43 regions already have a build from that month; the rest usually follow within a few weeks.

Which Android versions did it get?

The SM-X736B builds in the archive run Android 16 to 17. The earliest build we have for each version:

• Android 17: X736BXXU9CZJ7 (Oct 2026), 21 builds in total
• Android 16: X736BXXS5AZB8 (Mar 2026), 86 builds in total

Can I downgrade the SM-X736B firmware?

Only to builds with the same bootloader binary (the Bit column) or higher. In the archive the binary of this model rose from 5 to 9:

• Binary 9 — since Sep 2026
• Binary 8 — since Aug 2026
• Binary 7 — since Jul 2026
• Binary 6 — since Jun 2026
• Binary 5 — since Feb 2026

A phone already on binary 9 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 9 build. How to read a build number.
