Bios Mods -The Best BIOS Update and Modification Source

Hello

i'am new in this Forum and i hope you are able to help me with my Motherboard.. Its annoying because i think iam not that silly

First things first: 
My Board: P8H61-MX USB3 (Bios 1003)

What i want to do:
I just want to unlock my UEFI to enable the native Hackintosh sleep.. Maybe when iam able to flash, i'll try ozmosis.. But just maybe...


Problem:
I was not able to flash my Board with every tutorial i found..

i tried with afudos v. 3.07.x got: "Secure flash function is not supported on this file"


next i tried with the afudos from "How To Flash Unflashable AMI Bios" https://www.bios-mods.com/forum/Thread-H...e-AMI-Bios
got: "BIOS has no flash information available"

Tried with modified .CAP file via EZ-Flash... got "Security Validation failed"

Tried with modified .ROM file via EZ-Flash... got "...filename extension must be .CAP"

..I don't want to give up

My Board does not have the Flashback feature..


Can anyone help me? 


PS: i tried to uploaded the modified .ROM(Extracted from CAP) file but its to large..


EDIT: 
Please Move.. wrong Category. Sorry..

Got It!!!

Solution: I flashed it with the FTK8 (Flash Tool Kit v0.12.0) https://github.com/LongSoft/FTK/releases
