Samsung Galaxy A55 5G (SM-A5560) Firmware Overview
What is the latest SM-A5560 firmware?
A5560ZCSIDZJ1, released October 16, 2026 with Android 16. It is a security update on bootloader binary 18. The archive holds 23 official builds across 3 regions (CSC). Each one is the full stock ROM (flash file) for Odin, not an OTA patch.
Is the Samsung Galaxy A55 5G still getting updates?
Yes. The newest build is from October 2026, and 3 of 3 regions already have a build from that month; the rest usually follow within a few weeks.
Which Android versions did it get?
The SM-A5560 builds in the archive run Android 16 to 17. The earliest build we have for each version:
- Android 17: A5560ZHUIEZJ1 (Oct 2026), 2 builds in total
- Android 16: A5560ZCSECZD1 (Apr 2026), 21 builds in total
Can I downgrade the SM-A5560 firmware?
Only to builds with the same bootloader binary (the Bit column) or higher. In the archive the binary of this model rose from 14 to 18:
- Binary 18 — since Sep 2026
- Binary 17 — since Aug 2026
- Binary 16 — since Jul 2026
- Binary 15 — since Jun 2026
- Binary 14 — since Apr 2026
A phone already on binary 18 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 18 build. How to read a build number.
