Samsung SM-J337U Firmware Overview
What is the latest SM-J337U firmware?
J337UUES9BUK1, released April 19, 2022 with Android 9. It is a security update on bootloader binary 9. The archive holds 20 official builds across 2 regions (CSC).
Is the Samsung SM-J337U still getting updates?
Most likely not: there has been no new firmware since April 2022, so Android 9 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-J337U builds in the archive run Android 8 to 9. The earliest build we have for each version:
- Android 9: J337UUEU3BSI2 (Sep 2019), 18 builds in total
- Android 8: J337UUES3ASH3 (Sep 2019), 2 builds in total
Can I downgrade the SM-J337U firmware?
Only to builds with the same bootloader binary (the Bit column) or higher. In the archive the binary of this model rose from 3 to 9:
- Binary 9 — since Nov 2021
- Binary 8 — since May 2021
- Binary 7 — since Oct 2020
- Binary 6 — since May 2020
- Binary 5 — since Feb 2020
- Binary 4 — since Nov 2019
- Binary 3 — since Aug 2019
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.
