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).
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.
