Samsung Galaxy On5 (SM-G550FY) Firmware Overview
What is the latest SM-G550FY firmware?
G550FYXXU1CRF1, released June 26, 2018 with Android 7.1.1. It is a feature update on bootloader binary 1. The archive holds 20 official builds across 2 regions (CSC). Each one is the full stock ROM (flash file) for Odin, not an OTA patch.
Is the Samsung Galaxy On5 still getting updates?
Most likely not: there has been no new firmware since June 2018, 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-G550FY builds in the archive run Android 6.0.1 to 7.1.1. The earliest build we have for each version:
- Android 7.1.1: G550FYXXU1CQL6 (Dec 2017), 5 builds in total
- Android 6.0.1: G550FYXXU1BPJ2 (Oct 2016), 14 builds in total
Can I downgrade the SM-G550FY 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 Sep 2015
