Samsung Galaxy A55 5G (SM-A556E) Firmware Overview
What is the latest SM-A556E firmware?
A556EXXSIDZI3, released September 15, 2026 with Android 16. It is a security update on bootloader binary 18. The archive holds 182 official builds across 77 regions (CSC).
Is the Samsung Galaxy A55 5G still getting updates?
Yes. The newest build is from September 2026, and 21 of 77 regions already have a build from that month; the rest usually follow within a few weeks.
Can I downgrade the SM-A556E firmware?
Only to builds with the same bootloader binary (the Bit column) or higher. In the archive the binary of this model rose from 12 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
- Binary 13 — since Feb 2026
- Binary 12 — since Jan 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.
