Samsung Galaxy Tab S10 FE 5G (SM-X526B) Firmware Overview
What is the latest SM-X526B firmware?
X526BXXS9CZG3, released July 15, 2026 for region SIN with Android 16. It is a security update on bootloader binary 9. The archive holds 4 official builds for this region.
Is the Samsung Galaxy Tab S10 FE 5G still getting updates?
Yes. The newest build is from July 2026.
Can I downgrade the SM-X526B firmware?
Only to builds with the same bootloader binary (the Bit column) or higher. In the archive the binary of this model rose from 6 to 9:
- Binary 9 — since Jul 2026
- Binary 7 — since Feb 2026
- Binary 6 — since Jan 2026
A phone already on binary 9 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 9 build. How to read a build number.
