Samsung Galaxy A9 Star (SM-G8858) Firmware Overview
What is the latest SM-G8858 firmware?
G8858ZMU7CVC2, released April 15, 2022 with Android 10. It is a feature update on bootloader binary 7. The archive holds 20 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 A9 Star still getting updates?
Most likely not: there has been no new firmware since April 2022, so Android 10 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-G8858 builds in the archive run Android 9 to 10. The earliest build we have for each version:
- Android 10: G8858ZMU4CTD8 (Apr 2020), 9 builds in total
- Android 9: G8858ZMU3BSEB (May 2019), 11 builds in total
Can I downgrade the SM-G8858 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 7:
- Binary 7 — since Mar 2022
- Binary 6 — since Apr 2021
- Binary 5 — since Dec 2020
- Binary 4 — since Nov 2019
- Binary 3 — since May 2019
- Binary 2 — since Sep 2018
- Binary 1 — since Jun 2018
A phone already on binary 7 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 7 build. How to read a build number.
