Samsung SM-M205FN Firmware Overview
What is the latest SM-M205FN firmware?
M205FNEES9CVJ1, released October 18, 2022 for region PHN with Android 10. It is a security update on bootloader binary 9. The archive holds 2 official builds for this region.
Is the Samsung SM-M205FN still getting updates?
Most likely not: there has been no new firmware since October 2022, 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-M205FN firmware?
Only to builds with the same bootloader binary (the Bit column) or higher. In the archive the binary of this model rose from 8 to 9:
- Binary 9 — since Oct 2022
- Binary 8 — since Mar 2022
A phone already on binary 9 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 9 build. How to read a build number.
