Samsung Galaxy M35 5G (SM-M356B) Firmware Overview
What is the latest SM-M356B firmware?
M356BXXS9DZH5, released August 19, 2026 with Android 16. It is a security update on bootloader binary 9. The archive holds 47 official builds across 9 regions (CSC).
Is the Samsung Galaxy M35 5G still getting updates?
Yes. The newest build is from August 2026, and 9 of 9 regions already have a build from that month; the rest usually follow within a few weeks.
Can I downgrade the SM-M356B firmware?
Only to builds with the same bootloader binary (the Bit column) or higher. In the archive the binary of this model rose from 5 to 9:
- Binary 9 — since Aug 2026
- Binary 8 — since Apr 2026
- Binary 7 — since Feb 2026
- Binary 6 — since Jan 2026
- Binary 5 — since Sep 2025
A phone already on binary 9 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 9 build. How to read a build number.
