Samsung Galaxy J7 (SM-J727R4) Firmware Overview
What is the latest SM-J727R4 firmware?
J727R4TYU3BUD1, released July 29, 2021 with Android 8.1. It is a feature update on bootloader binary 3. The archive holds 20 official builds across 1 region (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 July 2021, 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-J727R4 builds in the archive run Android 7 to 8.1. The earliest build we have for each version:
- Android 8.1: J727R4TYU1BRH5 (Aug 2018), 9 builds in total
- Android 7: J727R4TYU1AQD4 (Apr 2017), 8 builds in total
Can I downgrade the SM-J727R4 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 3:
- Binary 3 — since Apr 2021
- Binary 2 — since Apr 2019
- Binary 1 — since Apr 2017
A phone already on binary 3 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 3 build. How to read a build number.
