Is the Samsung Galaxy Tab S9 FE 5G still getting updates?
Yes. The newest build is from September 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 11 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
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.
