Samsung Galaxy S26+ (SM-S9470) Firmware Overview
What is the latest SM-S9470 firmware?
S9470ZHU5BZJA, released October 16, 2026 with Android 17. It is a feature update on bootloader binary 5. The archive holds 23 official builds across 3 regions (CSC). Each one is the full stock ROM (flash file) for Odin, not an OTA patch.
Is the Samsung Galaxy S26+ still getting updates?
Yes. The newest build is from October 2026, and 3 of 3 regions already have a build from that month; the rest usually follow within a few weeks.
Which Android versions did it get?
The SM-S9470 builds in the archive run Android 16 to 17. The earliest build we have for each version:
- Android 17: S9470ZHU4BZI6 (Sep 2026), 6 builds in total
- Android 16: S9470ZHS2AZCL (Mar 2026), 17 builds in total
Can I downgrade the SM-S9470 firmware?
Only to builds with the same bootloader binary (the Bit column) or higher. In the archive the binary of this model rose from 2 to 5:
- Binary 5 — since Oct 2026
- Binary 4 — since Jul 2026
- Binary 3 — since Jun 2026
- Binary 2 — since Mar 2026
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.
