Samsung Galaxy Tab S3 (SM-T820) Firmware Overview
What is the latest SM-T820 firmware?
T820XXU3CTK1, released December 9, 2020 with Android 9. It is a feature update on bootloader binary 3. The archive holds 20 official builds across 20 regions (CSC). Each one is the full stock ROM (flash file) for Odin, not an OTA patch.
Is the Samsung Galaxy Tab S3 still getting updates?
Most likely not: there has been no new firmware since December 2020, so Android 9 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-T820 builds in the archive run Android 7 to 9. The earliest build we have for each version:
- Android 9: T820XXU3CTD5 (May 2020), 16 builds in total
- Android 8: T820XXU3CTD5 (Jun 2020), 2 builds in total
- Android 7: T820XXU3CTD5 (Jun 2020), 2 builds in total
Can I downgrade the SM-T820 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 3:
- Binary 3 — since Apr 2020
- Binary 2 — since Jul 2018
- Binary 1 — since Feb 2017
A phone already on binary 3 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 3 build. How to read a build number.
