Odin3 v3.12.5 Download for Windows

What’s different in Odin3 v3.12.5

Only 11 bytes are different. Both files carry the same internal build number, 2016.4.25.1, and the same compile date, April 28, 2016. The visible change is the product version, which reads 3.12.5.0 here.

You get BL, AP, CP, CSC and UMS slots and the Nand Erase option. The EXE records Windows subsystem version 6.0, the same value as v3.12.4. PE header record

Before you open Odin3 v3.12.5

Unzip it to a normal folder first, like your Desktop. Odin3.ini needs to sit right next to 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 v3.12.5

In practice, v3.12.4 and v3.12.5 are interchangeable. If a guide asks for one of them, either will do the same job. For current firmware, use v3.13.1 or newer.

Not sure if your firmware is too new? Open the AP file. If you see .lz4 files inside, this build can’t flash them.

The steps are the same as any other Odin build, and my Odin tutorial walks you through them.
