Samsung Galaxy A35 5G (SM-A356B) Firmware Overview
What is the latest SM-A356B firmware?
A356BXXSCDZH1, released August 18, 2026 with Android 16. It is a security update on bootloader binary 12. The archive holds 88 official builds across 16 regions (CSC).
Is the Samsung Galaxy A35 5G still getting updates?
Yes. The newest build is from August 2026, and 16 of 16 regions already have a build from that month; the rest usually follow within a few weeks.
Can I downgrade the SM-A356B firmware?
Only to builds with the same bootloader binary (the Bit column) or higher. In the archive the binary of this model rose from 7 to 12:
- Binary 12 — since Aug 2026
- Binary 11 — since Jul 2026
- Binary 10 — since Apr 2026
- Binary 9 — since Feb 2026
- Binary 8 — since Jan 2026
- Binary 7 — since Nov 2025
A phone already on binary 12 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 12 build. How to read a build number.
