Odin3 v3.12.7 is the last Odin build without .lz4 support. You’ll still see it linked in a lot of tutorials from 2016 and 2017.
Here’s the catch though. Current Samsung firmware uses .lz4 files, and this version can’t read them.

What’s different in Odin3 v3.12.7
I checked the version fields in the EXE inside this ZIP. The numeric file version is 2016.8.10.1, and the file version text says 2017.4.25.1. Both product version fields read 3.12.7.0. Odin 3.12.7 file record · Microsoft version field reference
The slots are BL, AP, CP, CSC and UMS, and the Options tab still has Phone EFS Clear and Phone Bootloader Update, which Samsung dropped in v3.13.1.
The EXE in this ZIP records Windows subsystem version 6.0. In the v3.12.3 EXE, that field reads 5.1. PE header record
Before you open Odin3 v3.12.7
Pull the files out of the ZIP before you open anything. Odin3.ini stores the default options, so it has to stay in the same folder as the exe.
Compare the SHA-256 to check that you downloaded the copy listed here. A match does not establish that the program is safe. Keep Windows security checks enabled and review any SmartScreen warning before opening it.
The minimum subsystem version is a file-header value. I cannot confirm Windows 10 or 11 compatibility from that field alone. Check Samsung’s USB driver separately.
When to use Odin3 v3.12.7
Use it for older .tar.md5 firmware when a guide for your device specifically calls for v3.12.7. It’s the newest Odin that still has the UMS slot and the Phone EFS Clear and Phone Bootloader Update boxes.
Here’s how to tell if your firmware is too new. Peek inside the AP file, and if the images end in .lz4, switch to v3.13.1 or a later build.
Keep those two Phone options unticked unless your guide says otherwise. The rest of the steps are in my Odin tutorial.
