Samsung Galaxy Tab S10 FE (SM-X520) Firmware Overview
What is the latest SM-X520 firmware?
X520XXSBCZI2, released September 10, 2026 with Android 16. It is a security update on bootloader binary 11. The archive holds 46 official builds across 21 regions (CSC).
Is the Samsung Galaxy Tab S10 FE still getting updates?
Yes. The newest build is from September 2026, and 21 of 21 regions already have a build from that month; the rest usually follow within a few weeks.
Can I downgrade the SM-X520 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 11:
- Binary 11 — since Sep 2026
- Binary 10 — since Aug 2026
- Binary 9 — since Jul 2026
- Binary 8 — since Jun 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.
