You'll need the SHSHs for the firmware you wanna downgrade to.

hahaha, you have a very powerfull machine but a lonely iphone being put away for now.
This is a true story :
One of the guy i helped he had a new bootrom. Apple was signing 3.1.3 at that time. I told him only old bootrom can accept custom firmware. You want to know what he actually did. He has a good friend and is a lady and she has the old bootrom. She doesn't care about jailbreaking. He asked her if he could swap her motherboard with his and she said Yes. He finally swaped out the board and put the old bootrom board into his phone and put his new bootrom into hers. Now he has the old bootrom and he was so happy that he immediately send a message on messenger to me. In returns he took her out for dinner and blah, blah, blah..
