Samsung Galaxy M05 (SM-M055F) Firmware Overview
What is the latest SM-M055F firmware?
M055FXXS9CZH5, released September 5, 2026 with Android 16. It is a security update on bootloader binary 9. The archive holds 16 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 M05 still getting updates?
Yes. The newest build is from September 2026, and 1 of 2 regions already have a build from that month; the rest usually follow within a few weeks.
Which Android versions did it get?
The SM-M055F builds in the archive run Android 14 to 16. The earliest build we have for each version:
- Android 16: M055FXXU5CYJ4 (Nov 2025), 5 builds in total
- Android 15: M055FXXS4BYG7 (Jul 2025), 3 builds in total
- Android 14: M055FXXU1AXH5 (Aug 2024), 8 builds in total
Can I downgrade the SM-M055F 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 9:
- Binary 9 — since Aug 2026
- Binary 8 — since May 2026
- Binary 7 — since Feb 2026
- Binary 6 — since Jan 2026
- Binary 5 — since Jul 2025
- Binary 4 — since May 2025
- Binary 3 — since Dec 2024
- Binary 2 — since Oct 2024
- Binary 1 — since Aug 2024
A phone already on binary 9 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 9 build. How to read a build number.
