i found the only programs needed are the finn editor and modio.
modio opens,resigns,rehashes and saves your file on to your flash drive.
...a very very simple process.
assuming you hav downloaded the save file :
1.save a backbreaker file onto your flashdrive from your xbox(created team preferably).
2. place your flash drive into your pc
3.open modio
4.click the large M in the upper left hand corner of the application
5.once you have clicked the M a drop down menu appears.scroll down to "explore my device"
6.next click file,then open/close drive. this will open your flash drive.
7.double click the content folder until you cascade through to the backbreaker folder.
8.once you see the file bbcust in the right panel right click it and select extract. this will allow you to move your save from your xbox to a folder on your pc. keep this file clos by because you will need it again.
9.once you move the bbcust file to a folder on your pc double click the word 'partition in the left panel. this will colapse your folders.
9.you should now see the content folder in the left panel.
10. right click it and delete the file from your flash drive.
11.close the device explorer wiindow.
12.click the large M in the upper left corner again. this time you will select "open resigner"
13. click load file in the upper middle of the screen. then select the bbcust file that you just move to your pc from your xbox.
14.with that window still open click the large M again in the upper left corner and select "open resigner" . you should now have 2 resigner windows open.
15. in the 2nd resigner window click theload file button in the upper middle of the screen and load the backbreaker file that you downloaded.
16.notice the profile id/device id of your original file and the file yougot from the net are different. copy your profile/device id to the resigner window with the downloaded backbreaker. you have to replace profile id/device id with your own so that your xbox can read it.
17.close the window with"the file you got from your xbox in it" and keep the downloade backbreaker file open.
18.click the button on the bottom in the resigner window on the bottom left that says resign/rehash(click it at least 2-3 times to be sure the process works), then in the top right corner of the resigner window you will see a save to device botton...click it.
19. next click the double tclick the number you see that begins eith E000...
20.you are now finished and ready to copy the file back to your xbox.
