Samsung SM-M105M Firmware Overview
What is the latest SM-M105M firmware?
M105MUBUACWC2, released March 13, 2023 with Android 10. It is a feature update on bootloader binary 10. The archive holds 20 official builds across 6 regions (CSC).
Is the Samsung SM-M105M still getting updates?
Most likely not: there has been no new firmware since March 2023, so Android 10 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-M105M 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 10:
- Binary 10 — since Feb 2023
- Binary 8 — since Jun 2022
- Binary 7 — since Jun 2021
A phone already on binary 10 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 10 build. How to read a build number.
