Samsung SM-M205N Firmware Overview
What is the latest SM-M205N firmware?
M205NKSU7BVG3, released August 4, 2022 with Android 10. It is a feature update on bootloader binary 7. The archive holds 18 official builds across 1 region (CSC). Each one is the full stock ROM (flash file) for Odin, not an OTA patch.
Is the Samsung SM-M205N still getting updates?
Most likely not: there has been no new firmware since August 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-M205N builds in the archive run Android 9 to 10. The earliest build we have for each version:
- Android 10: M205NKSU3BTC8 (Mar 2020), 14 builds in total
- Android 9: M205NKSU2ASH1 (Aug 2019), 4 builds in total
Can I downgrade the SM-M205N firmware?
Only to builds with the same bootloader binary (the Bit column) or higher. In the archive the binary of this model rose from 2 to 7:
- Binary 7 — since Oct 2021
- Binary 6 — since Mar 2021
- Binary 5 — since Dec 2020
- Binary 4 — since Aug 2020
- Binary 3 — since Nov 2019
- Binary 2 — since Aug 2019
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.
