The SM-E556B builds in the archive run Android 14 to 16. The earliest build we have for each version:

Can I downgrade the SM-E556B firmware?
Only to builds with the same bootloader binary (the Bit column) or higher. In the archive the binary of this model rose from 4 to 5:
- Binary 5 — since Feb 2026
- Binary 4 — since Dec 2024
A phone already on binary 5 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 5 build. How to read a build number.
