2021 Kia forte GT (BD) how to read TCU ID. And how to download SIMK-305 Patch > Q&A

Hello, I've tried to read my TCU ID. I've done both options. Reading ECU & Read ECU ID. My TCU is SIMK-305. In ECU ID, it takes 30-40 seconds before it fails. When I tried reading ECU and clicking SIMK-305, it says "connected to ECU," and I let it run for 10m, but to no avail. After hitting Ok, it just stays on the same screen.

I noticed there is a patch available called "[New Patch for OBD] Kia K3 GT TCU Patch DBD0T16SS0". I input my EK1 info and my VIN. After hitting the download button, it says "you do not have enough credits to download".

What am I supposed to do? My EK1 pro has the current update. Picture below.
