Samsung Galaxy Tab A (SM-T355) Firmware Overview
What is the latest SM-T355 firmware?
T355XXS1CTL3, released January 6, 2021 with Android 7.1.1. It is a security update on bootloader binary 1. The archive holds 20 official builds across 12 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 January 2021, 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-T355 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
