Samsung Galaxy Tab S10+ (SM-X820) Firmware Overview
What is the latest SM-X820 firmware?
X820XXSBDZI2, released September 10, 2026 with Android 16. It is a security update on bootloader binary 11. The archive holds 46 official builds across 20 regions (CSC).
Is the Samsung Galaxy Tab S10+ still getting updates?
Yes. The newest build is from September 2026, and 20 of 20 regions already have a build from that month; the rest usually follow within a few weeks.
Can I downgrade the SM-X820 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.
