Samsung SM-G8870 Firmware Overview
What is the latest SM-G8870 firmware?
G8870ZHU7CZB1, released April 22, 2026 with Android 10. It is a feature update on bootloader binary 7. The archive holds 20 official builds across 2 regions (CSC).
Is the Samsung SM-G8870 still getting updates?
Yes. The newest build is from April 2026, and 1 of 2 regions already have a build from that month; the rest usually follow within a few weeks.
Can I downgrade the SM-G8870 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 7:
- Binary 7 — since Sep 2021
- Binary 6 — since Apr 2021
- Binary 5 — since Jan 2021
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.
