[Request] Microcode downgrade on Gigabyte H97M D3H For Non-K Turbo Lock

Hi all, can anybody help me mod the H97M D3H bios with Microcode downgrade to rev 7 so that i can lock the max turbo for i7 4770s.
i have try using UBU tools from ver 1.69 to 1.80 all said success but when i flash it to the motherboerd via QFlash the mobo doesnt boot it just black screen, then i have to restore the bios with the dualbios pin method. maybe it had something to do with " 1. This BIOS prohibits updating to earlier version BIOS"
i have modded the bios before with “Rebar mod” and it work fine,
RebarF7.zip (5.1 MB)
i attached the bios im using right now that is F7 with the rebar mod
i know this is an old motherboard, but please help


above is the bios file after i change the 306C3 microcode, it has change to 7, but black screen when i flash to mobo
