[Request] Asus BT1AD BIOS mod to support Intel i5 4590S

Hello,
I am working on upgrading an existing asus BT1AD Desktop from an i3-4130 to an i5-4590S, the current bios I’m using is this BIOS, the latest from ASUS and with the i5 the computer turns on but does not show any image. (CPU is hot, drawing power) I have seen this thread already but the owner seems unresponsive!l at least for the moment. He upgraded successfully to an i7-4790S.
Could anyone guide me on how to do the same with the i5? He kindly left his modded bios in the thread, but it’s a .bin file and asus EZ-Flash only reads .CAD and I can’t use it, I think he somehow injected it another way (I am not too familiar with this stuff)
If you can help me I can provide some sort of compensation!
Thank you!
