Odin3 v3.09 is the build that renamed the slots. Before it, you loaded files into Bootloader, PDA and Phone. From v3.09 on, those became BL, AP and CP.
That’s why so many old guides say PDA while newer ones say AP. It’s the same slot.

What’s different in Odin3 v3.09
The internal build number is 2013.5.24.1, so it was built in May 2013, about four weeks after the Galaxy S4 went on sale. The slots are BL, AP, CP, CSC and UMS.
It keeps the Nand Erase All and T Flash options from v3.07. The exe grew to about 2.3 MB, which is why the ZIP jumps to around 1 MB. There are no tabs yet. Those came with v3.10.
Before you open Odin3 v3.09
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.
Install the Samsung USB driver first, then plug in the phone. Odin can’t see it without the driver.
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 v3.09
Use it if you’re following a 2013 or 2014 guide that asks for this exact build. A guide that says PDA works with it too. Just put the PDA file in AP.
On this build the slots read BL, AP, CP and CSC. The old Bootloader file goes in BL and the Phone file goes in CP.
The rest of the process is the same as today. My Odin tutorial uses the new slot names.
