Samsung Galaxy F55 5G (SM-E556B) Firmware Overview
What is the latest SM-E556B firmware?
E556BXXS5DZH1, released August 17, 2026 with Android 16. It is a security update on bootloader binary 5. The archive holds 17 official builds across 1 region (CSC). Each one is the full stock ROM (flash file) for Odin, not an OTA patch.
Is the Samsung Galaxy F55 5G still getting updates?
Yes. The newest build is from August 2026.
Which Android versions did it get?
The SM-E556B builds in the archive run Android 14 to 16. The earliest build we have for each version:
- Android 16: E556BXXU4CYJ4 (Oct 2025), 6 builds in total
- Android 15: E556BXXU4BYE7 (May 2025), 2 builds in total
- Android 14: E556BXXU1AXD7 (Apr 2024), 9 builds in total
Can I downgrade the SM-E556B firmware?
Only to builds with the same bootloader binary (the Bit column) or higher. In the archive the binary of this model rose from 1 to 5:
- Binary 5 — since Feb 2026
- Binary 4 — since Nov 2024
- Binary 3 — since Jul 2024
- Binary 2 — since May 2024
- Binary 1 — since Apr 2024
A phone already on binary 5 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 5 build. How to read a build number.
