Samsung Galaxy S10 (SM-G9730) Firmware Overview
What is the latest SM-G9730 firmware?
G9730ZCU8HZE1, released May 19, 2026 with Android 12. It is a feature update on bootloader binary 8. The archive holds 22 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 S10 still getting updates?
Yes. The newest build is from May 2026, and 2 of 2 regions already have a build from that month; the rest usually follow within a few weeks.
Which Android versions did it get?
The SM-G9730 builds in the archive run Android 11 to 12. The earliest build we have for each version:
- Android 12: G9730ZCU6GVA7 (Feb 2022), 20 builds in total
- Android 11: G9730ZCS6FVAZ (Jan 2022), 2 builds in total
Can I downgrade the SM-G9730 firmware?
Only to builds with the same bootloader binary (the Bit column) or higher. In the archive the binary of this model rose from 6 to 8:
- Binary 8 — since Dec 2022
- Binary 7 — since Oct 2022
- Binary 6 — since Jan 2022
A phone already on binary 8 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 8 build. How to read a build number.
