Samsung Galaxy Tab S10 FE+ 5G (SM-X626N) Firmware Overview
What is the latest SM-X626N firmware?
X626NKOUBDZJA, released October 27, 2026 with Android 17. It is a feature update on bootloader binary 11. The archive holds 11 official builds across 1 region (CSC). Each one is the full stock ROM (flash file) for Odin, not an OTA patch.
Is the Samsung Galaxy Tab S10 FE+ 5G still getting updates?
Yes. The newest build is from October 2026.
Which Android versions did it get?
The SM-X626N builds in the archive run Android 16 to 17. The earliest build we have for each version:
- Android 17: X626NKOUBDZJA (Oct 2026), 1 build in total
- Android 16: X626NKOU4BYI7 (Sep 2025), 9 builds in total
Can I downgrade the SM-X626N 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 11:
- Binary 11 — since Sep 2026
- Binary 10 — since Aug 2026
- Binary 9 — since Jul 2026
- Binary 8 — since Jun 2026
- Binary 7 — since Feb 2026
- Binary 6 — since Jan 2026
- Binary 5 — since Dec 2025
- Binary 4 — since Sep 2025
A phone already on binary 11 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 11 build. How to read a build number.
