Samsung Galaxy S7 (SM-G9308) Firmware Overview
What is the latest SM-G9308 firmware?
G9300ZCS5CTA1, released January 23, 2020 with Android 8. It is a security update on bootloader binary 5. The archive holds 15 official builds across 1 region (CSC). Each one is the full stock ROM (flash file) for Odin, not an OTA patch.
Is the Samsung Galaxy S7 still getting updates?
Most likely not: there has been no new firmware since January 2020, so Android 8 is the last version this model got. The final builds below are still the best choice for a clean reinstall.
Which Android versions did it get?
The SM-G9308 builds in the archive run Android 7 to 8. The earliest build we have for each version:
- Android 8: G9300ZCU2CRF5 (Jun 2018), 10 builds in total
- Android 7: G9300ZCU2BQC4 (Mar 2017), 4 builds in total
Can I downgrade the SM-G9308 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 Jan 2020
- Binary 4 — since Feb 2019
- Binary 3 — since Jul 2018
- Binary 2 — since Mar 2017
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.
