Samsung Galaxy Tab S9 FE 5G (SM-X518U) Firmware Overview
What is the latest SM-X518U firmware?
X518USQSHEZI3, released September 28, 2026 with Android 16. It is a security update on bootloader binary 17. The archive holds 89 official builds across 13 regions (CSC).
Is the Samsung Galaxy Tab S9 FE 5G still getting updates?
Yes. The newest build is from September 2026, and 13 of 13 regions already have a build from that month; the rest usually follow within a few weeks.
Can I downgrade the SM-X518U 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 17:
- Binary 17 — since Sep 2026
- Binary 16 — since Aug 2026
- Binary 15 — since Jul 2026
- Binary 14 — since Jun 2026
- Binary 13 — since Apr 2026
- Binary 12 — since Feb 2026
- Binary 11 — since Jan 2026
- Binary 10 — since Nov 2025
A phone already on binary 17 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 17 build. How to read a build number.
