Better get learning pal if you want to carry on modding, this is a pretty basic thing which has to be done in virtually everything to do with Xbox Modding.

As for the solution to your problem, I suggest getting Horizon or Modio, both programs which allow you to put a Save into and edit, both can be found in the download section of TTG. Once you have these drag your Downloaded Save into either Program and then Drag your own save into the Program. You will notice that YOUR save will have Digits, the other save might too but ignore them. Copy and paste your ID's which are clearly stated in the Save interface which comes up and place them into the Downloaded save. Close your save and then Rehash and Resign the save which you have put your ID's on to and then you can drag them onto Xport or your USB Drive. Pretty simple but everyone has to learn at some point.

ill help u mate pm me

JeremyisBetter wrote hey i downloaded a gamesave and i want to use it but in the tutorial of how to use it it said "replace with your id's" and i dont know what that means or how to do it so please help.

To replace with YOUR ids you need to have a configured USB or a transfer cable into your hardrive and into your PC I would suggest Modio for replacing IDS just google "Modio Download" Once you get Modio and have your save of the game you want to mod on your usb/transfer cable follow these steps: 1. On modio click Open a save and find the save you DOWNLOADED .
2.Put the save to the side and click Explore a Device and click File Open device.
3. Navigate through the folders until you find savegame.svg right click and click open in resigner.
4.The save that you just opened Copy your profile ID and Device ID onto the other save after deleting the other IDS on the save you downloaded.
5.Press Rehash and resign on both and then right click the file on your USB/Transfer Cable
6.Click inject file and select the save you downloaded.
7.Plug the USB into your Xbox and load up the game when the game asks you to pick a save device select USB or move the save onto your hard drive and your done!
