Samsung Galaxy Tab S2 (SM-T818) Firmware Overview
What is the latest SM-T818 firmware?
T818XXS2BTI1, released November 2, 2020 with Android 7. It is a security update on bootloader binary 2. The archive holds 13 official builds across 1 region (CSC). Each one is the full stock ROM (flash file) for Odin, not an OTA patch.
Is the Samsung Galaxy Tab S2 still getting updates?
Most likely not: there has been no new firmware since November 2020, so Android 7 is the last version this model got. The final builds below are still the best choice for a clean reinstall.
Which Android versions did it get?
The SM-T818 builds in the archive run Android 6.0.1 to 7. The earliest build we have for each version:
- Android 7: T818XXU2BQCO (Mar 2017), 10 builds in total
- Android 6.0.1: T818XXU1APJ3 (Oct 2016), 3 builds in total
Can I downgrade the SM-T818 firmware?
Only to builds with the same bootloader binary (the Bit column) or higher. In the archive the binary of this model rose from 1 to 2:
- Binary 2 — since Mar 2017
- Binary 1 — since Oct 2016
A phone already on binary 2 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 2 build. How to read a build number.
