Samsung Galaxy A05 (SM-A055F) Firmware Overview
What is the latest SM-A055F firmware?
A055FXXUJDZJ1, released October 15, 2026 with Android 15. It is a feature update on bootloader binary 19. The archive holds 59 official builds across 37 regions (CSC). Each one is the full stock ROM (flash file) for Odin, not an OTA patch.
Is the Samsung Galaxy A05 still getting updates?
Yes. The newest build is from October 2026, and 24 of 37 regions already have a build from that month; the rest usually follow within a few weeks.
Can I downgrade the SM-A055F firmware?
Only to builds with the same bootloader binary (the Bit column) or higher. In the archive the binary of this model rose from 17 to 19:
- Binary 19 — since Oct 2026
- Binary 18 — since Sep 2026
- Binary 17 — since Jun 2026
A phone already on binary 19 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 19 build. How to read a build number.
