Samsung Galaxy Tab Active2 (SM-T390) Firmware Overview
What is the latest SM-T390 firmware?
T390XXSACUI4, released November 2, 2021 for region XSA with Android 9. It is a security update on bootloader binary 10. The archive holds 2 official builds for this region.
Is the Samsung Galaxy Tab Active2 still getting updates?
Most likely not: there has been no new firmware since November 2021, so Android 9 is the last version this model got. The final builds below are still the best choice for a clean reinstall.
Can I downgrade the SM-T390 firmware?
Only to builds with the same bootloader binary (the Bit column) or higher. In the archive the binary of this model rose from 9 to 10:
- Binary 10 — since Sep 2021
- Binary 9 — since Jun 2021
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.
