Please help with transferring a Minecraft save

[Darko]

Let me start by saying I pretty much have no idea what I'm doing. Anyways, my friend and I have been building a medieval city in Minecraft for a while now but he has gotten somewhat bored with the game. Since he's the host, I can't play unless he's on. I asked him to send me the save and he sent me the .rar file. I did some research on here and thought I had gotten it right. I downloaded 7zip and used that to extract the file. Then I downloaded Horizon and used that program to inject the file onto my usb. Then I transferred the save to my hard drive on the xbox and loaded up Minecraft. The save showed up in my list of games but when I tried to load it up it wouldn't work. The title screen just continues to scroll indefinitely. So now I'm pretty much at a loss as to what to do. Any help would be greatly appreciated, thanks!

Put the file into horizon
then you need to change the profile and device ID to same as yours ( you can get this buy dragging one of your saves off your USB into horizon )
click resign and rehash then save to device.
