ROMAYU

hi, im trying for days to load a modded save into my dark souls game on the xbox360 devkit.
the game is way too hard for me ...
what i did is i tried installing the software MODIO and found a save. but after rehashing resigning and stfs resigned for devkit PURS the games gives me the error . save version differs from game version try connecting to xbox live.... so hopefully i tried to title update my game hoping that then i will be able to use the modded save from MODIO.i took the latest update for NTSC U then followed tutorials with le fluffie and xextools. after obtaining mynew default.xex i ran again the game hack soft and patched for devkit and transferred the game back to the xbox with neighborhood. the game launched fine in xna menu but when i created a new game and started the game with new character everything was messed up .. for instance there was a knight boss in front of the cell where the game start and he wouldnt let me pass also i couldnt run use weapon and just seemed like a bug. so i guess the update process went wrong.. can someone please just help me to load the modded save or update the game correctly... please...
also i tried the game save editor recently released coz u know i dont need to use an other person save but the game loaded fine with all souls etc... until i noticed that the game didnt save and mt party always restarted from the first bonfire......
thanks
