Samsung Galaxy M40 (SM-M405F) Firmware Overview
What is the latest SM-M405F firmware?
M405FDDU2CXE1, released June 11, 2024 with Android 11. It is a feature update on bootloader binary 2. The archive holds 20 official builds across 4 regions (CSC). Each one is the full stock ROM (flash file) for Odin, not an OTA patch.
Is the Samsung Galaxy M40 still getting updates?
Most likely not: there has been no new firmware since June 2024, 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-M405F firmware?
Only to builds with the same bootloader binary (the Bit column) or higher. All decodable builds in the archive share binary 2:
- Binary 2 — since Nov 2021
