Samsung SM-G977T Firmware Overview
What is the latest SM-G977T firmware?
G977TUVUCHXJ1, released October 4, 2024 with Android 12. It is a feature update on bootloader binary 12. The archive holds 20 official builds across 1 region (CSC).
Is the Samsung SM-G977T 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.
Which Android versions did it get?
The SM-G977T builds in the archive run Android 11 to 12. The earliest build we have for each version:
- Android 12: G977TUVU8GULD (Feb 2022), 12 builds in total
- Android 11: G977TUVU6FUE2 (Jun 2021), 8 builds in total
Can I downgrade the SM-G977T 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 12:
- Binary 12 — since Jul 2023
- Binary 11 — since May 2023
- Binary 10 — since Dec 2022
- Binary 9 — since Sep 2022
- Binary 8 — since Sep 2021
- Binary 7 — since Jul 2021
- Binary 6 — since May 2021
A phone already on binary 12 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 12 build. How to read a build number.
