Samsung Galaxy Tab A (SM-T550) Firmware Overview
What is the latest SM-T550 firmware?
T550XXS1CTI7, released October 12, 2020 with Android 6.0.1. It is a security update on bootloader binary 1. 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 A still getting updates?
Most likely not: there has been no new firmware since October 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.
Which Android versions did it get?
The SM-T550 builds in the archive run Android 5.0.2 to 7.1.1. The earliest build we have for each version:
- Android 7.1.1: T550XXU1CRG1 (Feb 2019), 8 builds in total
- Android 6.0.1: T550XXS1CTI7 (Oct 2020), 1 build in total
- Android 5.0.2: T550XXU1CRG1 (Feb 2019), 11 builds in total
Can I downgrade the SM-T550 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 Mar 2015
