Samsung SM-S337TL Firmware Overview
What is the latest SM-S337TL firmware?
S337TLUDS7BSK1, released November 1, 2019 with Android 7. It is a security update on bootloader binary 7. The archive holds 4 official builds across 1 region (CSC). Each one is the full stock ROM (flash file) for Odin, not an OTA patch.
Is the Samsung SM-S337TL still getting updates?
Most likely not: there has been no new firmware since November 2019, so Android 7 is the last version this model got. The final builds below are still the best choice for a clean reinstall.
Can I downgrade the SM-S337TL firmware?
Only to builds with the same bootloader binary (the Bit column) or higher. In the archive the binary of this model rose from 4 to 7:
- Binary 7 — since Nov 2019
- Binary 6 — since Jul 2019
- Binary 5 — since May 2019
- Binary 4 — since Jul 2018
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.

How to Flash SM-S337TL Firmware
