Samsung Galaxy M35 5G (SM-M356B) Firmware Overview
What is the latest SM-M356B firmware?
M356BXXU9EZJ2, released October 15, 2026 with Android 17. It is a feature update on bootloader binary 9. The archive holds 56 official builds across 9 regions (CSC). Each one is the full stock ROM (flash file) for Odin, not an OTA patch.
Is the Samsung Galaxy M35 5G still getting updates?
Yes. The newest build is from October 2026, and 9 of 9 regions already have a build from that month; the rest usually follow within a few weeks.
Which Android versions did it get?
The SM-M356B builds in the archive run Android 16 to 17. The earliest build we have for each version:
- Android 17: M356BXXU9EZJ2 (Oct 2026), 9 builds in total
- Android 16: M356BXXU5CYI8 (Oct 2025), 47 builds in total
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.
