Samsung Galaxy S10 5G (SM-G977U) Firmware Overview
What is the latest SM-G977U firmware?
G977UUCUAHXJ1, released October 5, 2024 with Android 12. It is a feature update on bootloader binary 10. 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 S10 5G still getting updates?
Most likely not: there has been no new firmware since October 2024, so Android 12 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-G977U 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 11:
- Binary 11 — since Jul 2023
- Binary 10 — since Dec 2022
- Binary 9 — since Dec 2022
- Binary 8 — since Mar 2022
- Binary 7 — since Apr 2022
A phone already on binary 11 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 11 build. How to read a build number.
