and to fix this go back into the modding program and set everything to sand or something you can get then go back to your xbox and check if it freezes or not if not you can try modding again but dont try and get stuff from 1.8.2

this happens to me i tryed to put some one else map so i didnt have to do anything and it just kept freezing my xbox

btw i havent had any updates for xbox or minercaft
so that may be the problem idk
