Samsung Galaxy Tab S10 FE 5G (SM-X526B) Firmware Overview
What is the latest SM-X526B firmware?
X526BXXSACZH6, released August 21, 2026 for region DKR with Android 16. It is a security update on bootloader binary 10. The archive holds 2 official builds for this region.
Is the Samsung Galaxy Tab S10 FE 5G still getting updates?
Yes. The newest build is from August 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 8 to 10:
- Binary 10 — since Aug 2026
- Binary 8 — since Jun 2026
A phone already on binary 10 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 10 build. How to read a build number.
