Unresolved minecraft inventory wont show up

I see several inventories filled with Iron Blocks. What is supposed to be in there?

 

Okay, walk me through what you do when you go to mod your inventory. Should be something like this:
1. Go into Minecraft and fill inventory with sandstone.
2. Save and exit.
3. Go to system setting>storage and move save to USB (if you're not playing it off there).
4. Open up 360rev and go into the USB Explorer.
5. Extract save to wherever.
6. Drag and drop save into 360rev.
7. Click Mod File and put in whatever you want. Save, Rehash, and Resign.
8. Open USB Explorer again and inject saved file into original location.
9. Plug USB into Xbox and copy file onto HDD or play straight off USB.
11. Open Minecraft and see new items.
Do you differ from this at all?

 

And the sandstone just isn't there?

 

Are you sure you're saving and exiting and overwriting the old save on the USB?

 

Then I have no idea what's going wrong. Try modding that old inventory and opening it. Do the items you modded in appear?

 

Are you SURE you save after modding by going into file>save and then seeing the popup box in the lower-right corner saying file saved, rehashed and resigned?

 

If this isn't resolved, would you be willing to download teamviewer 7 so I can actually see what your doing in real time?
