Samsung Galaxy A36 5G (SM-A366B) Firmware Overview
What is the latest SM-A366B firmware?
A366BXXUCDZIF, released September 29, 2026 with Android 17. It is a feature update on bootloader binary 12. The archive holds 141 official builds across 46 regions (CSC).
Is the Samsung Galaxy A36 5G still getting updates?
Yes. The newest build is from September 2026, and 21 of 46 regions already have a build from that month; the rest usually follow within a few weeks.
Which Android versions did it get?
The SM-A366B builds in the archive run Android 16 to 17. The earliest build we have for each version:
- Android 17: A366BXXUCDZIF (Sep 2026), 21 builds in total
- Android 16: A366BXXS7BZA1 (Jan 2026), 120 builds in total
Can I downgrade the SM-A366B firmware?
Only to builds with the same bootloader binary (the Bit column) or higher. In the archive the binary of this model rose from 7 to 12:
- Binary 12 — since Aug 2026
- Binary 11 — since Jul 2026
- Binary 10 — since May 2026
- Binary 8 — since Feb 2026
- Binary 7 — since Jan 2026
A phone already on binary 12 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 12 build. How to read a build number.
