Samsung Galaxy M20 (SM-M205M) Firmware Overview
What is the latest SM-M205M firmware?
M205MUBU8CWC2, released March 12, 2023 with Android 10. It is a feature update on bootloader binary 8. The archive holds 20 official builds across 5 regions (CSC). Each one is the full stock ROM (flash file) for Odin, not an OTA patch.
Is the Samsung Galaxy M20 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-M205M firmware?
Only to builds with the same bootloader binary (the Bit column) or higher. All decodable builds in the archive share binary 8:
- Binary 8 — since Sep 2021
