Samsung Galaxy A56 5G (SM-A566E) Firmware Overview
What is the latest SM-A566E firmware?
A566EXXUEDZJ1, released October 3, 2026 with Android 17. It is a feature update on bootloader binary 14. The archive holds 150 official builds across 47 regions (CSC).
Is the Samsung Galaxy A56 5G still getting updates?
Yes. The newest build is from October 2026, and 15 of 47 regions already have a build from that month; the rest usually follow within a few weeks.
Which Android versions did it get?
The SM-A566E builds in the archive run Android 16 to 17. The earliest build we have for each version:
- Android 17: A566EXXUEDZJ1 (Oct 2026), 15 builds in total
- Android 16: A566EXXS8BZA1 (Jan 2026), 135 builds in total
Can I downgrade the SM-A566E firmware?
Only to builds with the same bootloader binary (the Bit column) or higher. In the archive the binary of this model rose from 8 to 14:
- Binary 14 — since Sep 2026
- Binary 13 — since Aug 2026
- Binary 12 — since Jul 2026
- Binary 11 — since Jun 2026
- Binary 10 — since May 2026
- Binary 9 — since Feb 2026
- Binary 8 — since Jan 2026
A phone already on binary 14 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 14 build. How to read a build number.
