Samsung Galaxy Tab S9 FE 5G (SM-X518U) Firmware Overview
What is the latest SM-X518U firmware?
X518UVLSFEZG3, released July 27, 2026 for region FMC with Android 16. It is a security update on bootloader binary 15. The archive holds 6 official builds for this region.
Is the Samsung Galaxy Tab S9 FE 5G still getting updates?
Yes. The newest build is from July 2026.
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 15:
- 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 15 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 15 build. How to read a build number.
