Samsung Galaxy S8 (SM-G9500) Firmware Overview
What is the latest SM-G9500 firmware?
G9500ZHS6DUD1, released April 27, 2021 with Android 9. It is a security update on bootloader binary 6. The archive holds 20 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 S8 still getting updates?
Most likely not: there has been no new firmware since April 2021, so Android 9 is the last version this model got. The final builds below are still the best choice for a clean reinstall.
Can I downgrade the SM-G9500 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 6:
- Binary 6 — since Jul 2020
- Binary 5 — since Jan 2020
- Binary 3 — since Jul 2018
- Binary 2 — since Nov 2017
- Binary 1 — since May 2017
A phone already on binary 6 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 6 build. How to read a build number.
