Samsung Galaxy A50s (SM-A507FN) Firmware Overview
What is the latest SM-A507FN firmware?
A507FNXXS7DWD1, released May 22, 2023 for region XXV with Android 11. It is a security update on bootloader binary 7. The archive holds 2 official builds for this region.
Is the Samsung Galaxy A50s still getting updates?
Most likely not: there has been no new firmware since May 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-A507FN firmware?
Only to builds with the same bootloader binary (the Bit column) or higher. In the archive the binary of this model rose from 6 to 7:
- Binary 7 — since Apr 2023
- Binary 6 — since Oct 2022
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.
