Odin3 v1.86 is the last v1 build in our archive. It dates to August 2011, the Galaxy S II year.
It’s the build to grab when an old guide shows only PIT, PDA, PHONE and CSC slots and asks for v1.86.

What’s different in Odin3 v1.86
The compile date reads August 10, 2011. The slots are PIT, PDA, PHONE and CSC. There’s no separate Bootloader slot yet.
It’s the only v1 build here that comes with an Odin3.ini file. The defaults keep Auto Reboot and F. Reset Time on, and Re-Partition and Flash Lock off. The whole ZIP is only about 204 KB.
Before you open Odin3 v1.86
Unzip it and keep Odin3.ini with the exe. This is the only v1 build that ships with one, and it sets the defaults.
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 v1.86
Use it only for 2010 and 2011 Galaxy devices when a guide asks for it. It won’t help with any modern phone.
There’s no AP or BL here. Your PDA file goes in PDA, the modem goes in PHONE, and CSC goes in CSC.
A newer PC can open this old Odin, but it won’t make it work with a new phone. For anything recent, get the latest Odin.
