Samsung Galaxy Tab A (SM-T355Y) Firmware Overview
What is the latest SM-T355Y firmware?
T355YDOS1CTJ2, released December 10, 2020 with Android 7.1.1. It is a security update on bootloader binary 1. The archive holds 20 official builds across 6 regions (CSC). Each one is the full stock ROM (flash file) for Odin, not an OTA patch.
Is the Samsung Galaxy Tab A still getting updates?
Most likely not: there has been no new firmware since December 2020, so Android 7.1.1 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-T355Y firmware?
Only to builds with the same bootloader binary (the Bit column) or higher. All decodable builds in the archive share binary 1:
- Binary 1 — since Apr 2015
