Samsung Galaxy A20s (SM-A207M) Firmware Overview
What is the latest SM-A207M firmware?
A207MUBS4CWF1, released September 27, 2023 with Android 11. It is a security update on bootloader binary 4. The archive holds 20 official builds across 20 regions (CSC). Each one is the full stock ROM (flash file) for Odin, not an OTA patch.
Is the Samsung Galaxy A20s still getting updates?
Most likely not: there has been no new firmware since September 2023, so Android 11 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-A207M firmware?
Only to builds with the same bootloader binary (the Bit column) or higher. All decodable builds in the archive share binary 4:
- Binary 4 — since Jun 2023
