Samsung Galaxy J7 (SM-J727U) Firmware Overview
What is the latest SM-J727U firmware?
J727UUES9BTK1, released December 17, 2020 with Android 8.1. It is a security update on bootloader binary 9. The archive holds 20 official builds across 2 regions (CSC). Each one is the full stock ROM (flash file) for Odin, not an OTA patch.
Is the Samsung Galaxy J7 still getting updates?
Most likely not: there has been no new firmware since December 2020, so Android 8.1 is the last version this model got. The final builds below are still the best choice for a clean reinstall.
Which Android versions did it get?
The SM-J727U builds in the archive run Android 7 to 8.1. The earliest build we have for each version:
- Android 8.1: J727UUEU3BRJ2 (Oct 2018), 13 builds in total
- Android 7: J727UUES2AQL1 (Dec 2017), 7 builds in total
Can I downgrade the SM-J727U firmware?
Only to builds with the same bootloader binary (the Bit column) or higher. In the archive the binary of this model rose from 1 to 9:
- Binary 9 — since Nov 2020
- Binary 8 — since Jun 2020
- Binary 7 — since Nov 2019
- Binary 6 — since Jun 2019
- Binary 5 — since Mar 2019
- Binary 4 — since Dec 2018
- Binary 3 — since Feb 2018
- Binary 2 — since Dec 2017
- Binary 1 — since Jun 2017
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.
