Samsung Galaxy Tab S10 FE+ 5G (SM-X626B) Firmware Overview
What is the latest SM-X626B firmware?
X626BXXSBCZI2, released September 10, 2026 for region MWD with Android 16. It is a security update on bootloader binary 11. The archive holds 3 official builds for this region. 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 September 2026.
Can I downgrade the SM-X626B firmware?
Only to builds with the same bootloader binary (the Bit column) or higher. In the archive the binary of this model rose from 7 to 11:
- Binary 11 — since Sep 2026
- Binary 9 — since Jul 2026
- Binary 7 — since May 2026
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.
