Odin3 v3.04 Download for Windows

What’s different in Odin3 v3.04

The compile date reads January 16, 2012, and the version resource says 3.00. This build adds Bootloader and UMS slots, so you get Bootloader, PDA, Phone, CSC and UMS, plus PIT.

It needs tmax.dll and zlib.dll in the same folder, and both are in the ZIP. It’s also the first build here whose Odin3.ini has a ButtonOption section that sets which slots are enabled.

Before you open Odin3 v3.04

Keep the exe, tmax.dll and zlib.dll in the same folder. Moving the exe out on its own breaks 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.

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.

When to use Odin3 v3.04

Use it only for early Galaxy devices when a guide asks for v3.04. If you just need a v3 build for an old phone, v3.07 is the one most guides use.

Firmware for phones this old often came in two or three parts, like PDA, Phone and CSC. Load each file into the slot with the same name.
